Fix data races triggered by functional tests. (#4247)
Function CWallet::KeepKey requires locking as it has concurrent access to database and member nKeysLeftSinceAutoBackup.

Avoid data race when reading setInventoryTxToSend size by locking the read. If locking happens after the read, the size may change.

Lock cs_mnauth when reading verifiedProRegTxHash.

Make fRPCRunning atomic as it can be read/written from different threads simultaneously.

Make m_masternode_iqr_connection atomic as it can be read/written from different threads simultaneously.

Use a recursive mutex to synchronize concurrent access to quorumVvec.

Make m_masternode_connection atomic as it can be read/written from different threads simultaneously.

Make m_masternode_probe_connection atomic as it can be read/written from different threads simultaneously.

Use a recursive mutex in order to lock access to activeMasterNode.

Use a recursive mutex to synchronize concurrent access to skShare.

Guarded all mnauth fields of a CNode.

12972fe88e refactor: utilize GetLLMQParams, make it const, consistent naming
Removes all (besides one) usages of "Params().GetConsensus().llmqs.at" and instead uses the wrapper in quorum_utils.cpp

Rename all params to llmq_params for consistency and not conflict with non-llmq params

make some llmq_params const where possible

remove unneeded llmq_params variables where it's only used once

Pull request description:

  This PR adds an optional (off by default) `-avoidpartialspends` flag, which changes coin select to use output groups rather than outputs, where each output group corresponds to all outputs with the same destination.

  It is a privacy improvement, as each time you spend some output, any other output that is publicly associated with the destination (address) will also be spent at the same time, at the cost of fee increase for cases where coin select without group restriction would find a more optimal set of coins (see example below).

  For regular use without address reuse, this PR should have no effect on the user experience whatsoever; it only affects users who, for some reason, have multiple outputs with the same destination (i.e. address reuse).

  Nodes with this turned off will still try to avoid partial spending, if the fee of the resulting transaction is not greater than the fee of the original transaction.

  Example: a node has four outputs linked to two addresses `A` and `B`:

  * 1.0 btc to `A`
  * 0.5 btc to `A`
  * 1.0 btc to `B`
  * 0.5 btc to `B`

  The node sends 0.2 btc to `C`. Without `-avoidpartialspends`, the following coin selection will occur:
  * 0.5 btc to `A` or `B` is picked
  * 0.2 btc is output to `C`
  * 0.3 - fee is output to (unique change address)

  With `-avoidpartialspends`, the following will instead happen:
  * Both of (0.5, 1.0) btc to `A` or `B` is picked (one or the other pair)
  * 0.2 btc is output to `C`
  * 1.3 - fee is output to (unique change address)

  As noted, the pro here is that, assuming nobody sends to the address after you spend from it, you will only ever use one address once. The con is that the transaction becomes slightly larger in this case, because it is overpicking outputs to adhere to the no partial spending rule.

  This complements #10386, in particular it addresses @luke-jr and @gmaxwell's concerns in https://github.com/bitcoin/bitcoin/pull/10386#issuecomment-300667926 and https://github.com/bitcoin/bitcoin/pull/10386#issuecomment-302361381.

  Together with `-avoidreuse`, this fully addresses the concerns in #10065 I believe.

Pull request description:

  I'm re-opening #11857 as a new pull request because the last one stopped loading for people

  -------------------------------

  This refactors the tx index code to be in it's own class and get built concurrently with validation code. The main benefit is decoupling and moving the txindex into a separate DB. The primary motivation is to lay the groundwork for other indexers that might be desired (such as the [compact filters](https://github.com/bitcoin/bips/pull/636)). The basic idea is that the TxIndex spins up its own thread, which first syncs the txindex to the current block index, then once in sync the BlockConnected ValidationInterface hook writes new blocks.

  ### DB changes

  At the suggestion of some other developers, the txindex has been split out into a separate database. A data migration runs at startup on any nodes with a legacy txindex. Currently the migration blocks node initialization until complete.

  ### Open questions

  - Should the migration of txindex data from the old DB to the new DB block in init or should it happen in a background thread? The downside to backgrounding it is that `getrawtransaction` would return an error message saying the txindex is syncing while the migration is running.

  ### Impact

  In a sample size n=1 test where I synced nodes from scratch, the average time [Index writing](https://github.com/bitcoin/bitcoin/blob/master/src/validation.cpp#L1903) was 3.36ms in master and 1.72ms in this branch. The average time between `UpdateTip` log lines for sequential blocks between 400,000 and IBD end on mainnet was 0.297204s in master and 0.286134s in this branch. Most likely this is just variance in IBD times, but I can try with some more trials if people want.

chainlocks: Run CheckActiveState before processing new CLSIG (#4042)
This avoids race condition for "spork19 off, spork 19 on" situations when some nodes might call CheckActiveState already, created new clsig and sent it so that other nodes processed it too already but they will call CheckActiveState afterwards (because it's done every 5 sec) and reset best chainlock to null.

llmq|init|test: Add "mode" to -llmq-qvvec-sync parameter (#4030)
* llmq|init|test: Add "mode" to -llmq-qvvec-sync parameter

This changes the paramter from `-llmq-qvvec-sync=<quorum_name>` to `-llmq-qvvec-sync=<quorum_name:mode>`

With the following definitions:

- `quorum_name`: Internal name of the quorum type
- `mode=0` - Sync always from all quorums of the type defined by `quorum_name`
- `mode=1` - Sync only if member of any from all other quorum of the type defined by `quorum_name`

`-llmq-qvvec-sync=llmq_100_67:0` To always request qvvec's from all `LLMQ_100_67`.
`-llmq-qvvec-sync=llmq_100_67:1` Only request if type member.

This means, if platform enables this on all MNs with `mode=0` we will
have all nodes asking new quorum for their verification vector instead
of only `24*100` at max.

* llmq: Adjust GetQuorumRecoveryStartOffset to use all MNs

* Turn `QvvecSyncMode` into `enum class`

"test_mnauth_restriction", "test_invalid_messages" and "test_invalid_unexpected_qdata" with the resulting name "test_basics" because i don't feel like DKG recovery thing should be part of a test called "test_invalid_messages" and giving it an own test probably wouldn't make a lot sense because it would still depend on "test_invalid_messages". I also think there is no need for a separated "test_invalid_unexpected_qdata".

* test: Rename test_ratelimiting_banscore -> test_request_limit

* test: Apply python style

* test: Wrap all at 120 characters

Thats the default "draw annoying warnings" setting for PyCharm (and IMO a reasonable line length).

* test: Move some variables

I decided to don't cache here since its probably very unlikely this is called twice in a short period with what we have planed for it so far. We can add caching if the requirement for it changes at some point?

llmq: Restrict ShouldSimulateError to trigger for LLMQ_TEST only (#3871)
* llmq: Restrict `ShouldSimulateError` to trigger for LLMQ_TEST only

Current `develop` tests fail. This was basically introduced by dashpay#3844 but it didn't come up before dashpay#3853 because the `v17` fork wasn't activated in `feature_llmq_dkgerrors.py`.

After  dashpay#3853 `dip0008` activation takes [200 blocks](b95cf017c3 (diff-4a04bc0b355c780033960e8c261ee9b6d3c452897e1dcd88a15d272512266c76R539)) which was normally activated after [10 blocks](b95cf017c3 (diff-b92fa0fafafa27172736ebc88f9f9b658b1160caca512a318eefb7d93d22bf3cL18)) in `feature_llmq_dkgerrors.py`. Now with the 200 blocks `v17` gets activated during test which then leads to MN1, MN2 banning MN0 because it lies in DKG of `LLMQ_TEST` and `LLMQ_TEST_V17`.

There are other ways to solve it, like enabling `dip0008` earlier or enable `v17` later but IMO its anyway better to restrict `ShouldSimulateError` to only trigger for `LLMQ_TEST`.

* Revert "llmq: Restrict `ShouldSimulateError` to trigger for LLMQ_TEST only"

This reverts commit ec42d86126.

* llmq: Restrict `ShouldSimulateError` to trigger for LLMQ_TEST only (alternative)

Move ShouldSimulateError into CDKGSession

llmq: Fix spork check in CSigSharesManager::ForceReAnnouncement (#3650)
It seems like the idea here was to avoid announcing already available sigshares for a signhash to everyone if concentrated recovery is enabled. But by returning there if `IsAllMembersConnectedEnabled` equals to `false` we disable the re-announcements prior to the spork activation, where we want to still have them and re-enable if the spork is enabled where we don't want to have them.

When taking the proTxHash naively, we might end up with a few unlucky MNs

unlucky MNs would always have to wait for inbound connections. Hashing
the proTxHash with the quorum hash makes this more random.

We have version control systems for a reason, if we want code to not run it should be removed. I personally see no value in keeping these around. I presume at one point they were spamming debug.log so we commented them out, but we really should have just removed them.

I believe all of this is dash specific code but any conflicts this does create are so minor they are not of concern imo.

Remove recovered sigs from the LLMQ db when corresponding IS locks get confirmed (#3048)
* Remove unused overload of RemoveInstantSendLock

* Move deletion of recovered sigs into own method

* Remove recovered sigs for fully confirmed IS locks

* Also remove rs_t entries when removing recovered sigs from the outside

CleanupOldRecoveredSigs already does this as the last step, but when
RemoveRecoveredSig is called from the outside (e.g. from InstantSend),
these keys are not removed. This PR fixes this by storing the write time
into rs_r and later uses it to remove the rs_t entry.

Old entries will be incompatible with this (1 byte written in the past,
4 bytes written now). This checked by comparing the data size with
sizeof(uint32_t).

2f21e55514 Remove legacy InstantSend code (#3020)
* Remove ppszTypeName from protocol.cpp and reimplement GetCommand

This removes the need to carefully maintain ppszTypeName, which required
correct order and also did not allow to permanently remove old message
types.

To get the command name for an INV type, GetCommandInternal uses a switch
which needs to be maintained from now on.

The way this is implemented also resembles the way it is implemented in
Bitcoin today, but it's not identical. The original PR that introduced the
switch case in Bitcoin was part of the Segwit changes and thus never got
backported. I decided to implement it in a slightly different way that
avoids throwing exceptions when an unknown INV type is encountered.

IsKnownType will now also leverage GetCommandInternal() to figure out if
the INV type is known locally. This has the side effect of old/legacy
message types to return false from now on. We will depend on this side
effect in later commits when we remove legacy InstantSend code.

* Stop handling/relaying legacy IX messages

When we receive an IX message, we simply treat it as a regular TX and relay
it as such.

We'll however still request IX messages when they are announced to us. We
can't simply revert to requesting TX messages in this case as it might
result in the other peer not answering due to the TX not being in mapRelay
yet. We should at some point in the future completely drop handling of IX
messages instead.

* Remove IsNewInstantSendEnabled() and only use IsInstantSendEnabled()

* Remove legacy InstantSend from GUI

* Remove InstantSend from Bitcoin/Dash URIs

* Remove legacy InstantSend from RPC commands

* Remove legacy InstantSend from wallet

* Remove legacy instantsend.h include

* Remove legacy InstantSend from validation code

* Completely remove remaining legacy InstantSend code

* Remove now unused spork

* Fix InstantSend related test failures

* Remove now obsolete auto IS tests

* Make spork2 and spork3 disabled by default

This should have no influence on mainnet as these sporks are actually set
there. This will however affect regtest, which shouldn't have LLMQ based
InstantSend enabled by default.

* Remove instantsend tests from dip3-deterministicmns.py

These were only testing legacy InstantSend

* Fix .QCheckBox#checkUsePrivateSend styling a bit

* s/TXLEGACYLOCKREQUEST/LEGACYTXLOCKREQUEST/

* Revert "verified via InstantSend" back to "verified via LLMQ based InstantSend"

7a440d626b Optimize on-disk deterministic masternode storage to reduce size of evodb (#3017)
* Implement CompactFull() in CDBWrapper

This allows to compact the whole DB in one go.

* Implement more compact version of CDeterministicMNListDiff

This introduces CDeterministicMNStateDiff which requires to only store
fields on-disk which actually changed.

* Avoid writing mnUniquePropertyMap to disk when storing snapshots

This map can be rebuilt by simply using AddMN for each deserialized MN.

* Implement Serialize/Unserialize in CScript

This allows us to directly use READWRITE() on scripts and removes the need
for the ugly cast to CScriptBase. This commit also changes all Dash specific
uses of CScript to not use the cast.

* Keep track of registeration counts and introduce internalID for masternodes

The "internalId" is simply the number of MNs registered so far when the
new MN is added. It is deterministic and stays the same forever.

* Use internalId as keys in MN list diffs

This reduces the used size on-disk.

* Two simple speedups in MN list diff handling

1. Avoid full compare if dmn or state pointers match in BuildDiff
2. Use std::move when adding diff to listDiff in GetListForBlock

* Implement upgrade code for old CDeterministicMNListDiff format to new format

* Track tipIndex instead of tipHeight/tipBlockHash

* Store and pass around CBlockIndex* instead of block hash and height

This allows us to switch CDeterministicMNManager::GetListForBlock to work
with CBlockIndex.

* Refactor CDeterministicMNManager::GetListForBlock to require CBlockIndex*

Instead of requiring a block hash. This allows us to remove blockHash and
prevBlockHash from CDeterministicMNListDiff without the use of cs_main
locks in GetListForBlock.

* Remove prevBlockHash, blockHash and nHeight from CDeterministicMNListDiff

* Remove access to determinisitcMNManager in CMasternodeMetaMan::ToString()

The deterministic MN manager is not fully initialized yet at the time this
is called, which results in an empty list being returned everytime.

* Better logic to determine if an upgrade is needed

Reuse the "best block" logic to figure out if an upgrade is needed. Also
use it to ensure that older nodes are unable to start after the upgrade
was performed.

* Return null block hash if it was requested with getmnlistdiff

* bump CGovernanceManager::SERIALIZATION_VERSION_STRING

* Check SERIALIZATION_VERSION_STRING before deserializing anything else

* Invoke Clear() before deserializing just to be sure

This avoids updating the UI on every block, which turned out to be very
expensive.

Fix db leaks in LLMQ db (#2914)
* Store rs_t key time in big endian

Also implement ConvertInvalidTimeKeys to convert old entries. We can remove
this later when we know that most MNs have run this code on testnet.

The way we stored the time field in the past lead to CleanupOldRecoveredSigs
iterating the keys in a strange order, causing no deletion at all and the
LLMQ DB filling up.

* Write batch in CleanupOldRecoveredSigs when it gets too large

This avoids RAM filling up and OOM getting triggered.

* Keep track of when a vote was written to the DB and clean up after week

Instead of only deleting when the corresponding recovered sig is deleted.
It sometimes happens that a masternode votes on something but a recovered
sig is never created, which leaves us with a vote that will never be
deleted.

* Apply suggestions from code review

* Implement GetInstantSendLocksByParent and RemoveChainedInstantSendLocks

These allow to easily delete multiple chains (actually trees) of ISLOCKs

skip retrying of non-locked children TXs.

* Properly handle/remove conflicted TXs (between mempool and new blocks)

* Track non-locked TXs by inputs

* Implement and call ResolveBlockConflicts

* Also call ResolveBlockConflicts from ConnectBlock

But only when a block is known to have a conflict and at the same time is
ChainLocked, which causes the ISLOCK to be pruned.

* Ask for locked TXs after removing conflicting TXs

When we removed a conflicting TX from the mempool, the correct/locked TX
is not available locally as the first-seen rule would have filtered before.
We need to re-request this TX if any other node announced it before.

* Protect fresh incoming connections for a second from eviction

Give fresh connections some time to do the VERSION/VERACK handshake and
an optional MNAUTH when it's a masternode. When an MNAUTH happened, the
incoming connection is then forever protected against eviction.

If a timeout of 1 second occurs or the first message after VERACK is not
MNAUTH, the node is not protected anymore and becomes eligable for
eviction.

* Avoid connecting to masternodes if an incoming connection is from the same one

Now that incoming connections from MNs authenticate them self, we can avoid

Fix loop in CLLMQUtils::GetQuorumConnections to add at least 2 connections (#2796)
* Fix warning about size_t to int conversion

* Fix loop in CLLMQUtils::GetQuorumConnections to add at least 2 connections

When reaching very small quorum sizes, the current algorithm results in
only a single connection to be added. This would be fine usually, but is an
issue when this connection fails. We should always have at least one backup
connection.

This fixes simple PoSe test failures where the quorum size gets down to 4
with one of the 4 members being down. If other nodes are unlucky to connect
to this node, they fail as well even though 3 members in a quorum should
work fine.

c3602372cc Implement retroactive IS locking of transactions first seen in blocks instead of mempool (#2770)
* Don't rely on UTXO set in CheckCanLock

The UTXO set only works for TXs in the mempool and won't work when we try
to retroactively lock unlocked TXs from blocks.

This is safe as ProcessTx is only called when a TX was accepted into the
mempool or connected in a block, which means that all input checks were
good.

* Rename RetryLockMempoolTxs to RetryLockTxs and let it retry connected TXs

* Instead of manually calling ProcessTx, let SyncTransaction handle all cases

SyncTransaction is called from AcceptToMemoryPool and when transactions got
connected in a block. So this is the time we want to run TXs through
ProcessTx. This also enables retroactive signing of TXs that were unknown
before a new block appeared.

* Test retroactive signing and safe TXs in LLMQ ChainLocks tests

* Also test for retroactive signing of chained TXs

* Honor lockedParentTx when looking for TXs to retry signing

* Stop scanning for TXs to retry after a depth of 6

* Generate 6 block to avoid retroactive signing overloading Travis

* Avoid retroactive signing

* Don't rely on NewPoWValidBlock and use SyncTransaction to build blockTxs

NewPoWValidBlock is not guaranteed to be called when blocks come in fast.
When a block is accepted in AcceptBlock, NewPoWValidBlock is only called
when the new block is a successor of the currently active tip. This is not
the case when after the first block a second block is accepted immediately
as the first block is not connected yet.

This might be a bug actually in the handling of NewPoWValidBlock, so we
might need to check/fix this later, but currently I prefer to not touch
that part.

Instead, we now use SyncTransaction to gather TXs for blockTxs. This works
because SyncTransaction is called for all transactions in a freshly
connected block in one go. The call also happens before UpdatedBlockTip is
called, so it's fine with the existing logic.

* Use tx.IsCoinBase() instead of checking index 0

Also check for empty vin.

5299d39338 Multiple refactorings/fixes for LLMQ bases InstantSend and ChainLocks (#2779)
* Remove unused parameters from CInstantSendManager::ProcessTx

* Pass txHash in CheckCanLock by reference instead of pointer

* Dont' allow locking of TXs without inputs

* Remove unused local variable nInstantSendConfirmationsRequired

* Don't subtract 1 from nInstantSendConfirmationsRequired

This was necessary in the old system but is not necessary in the new system.
It also prevented proper retroactive signing of chained TXs in regtest as
it resulted in child TXs to return true immediately for CheckCanLock when
it should actually have waited for the parent TX to become locked first.

* Access chainActive.Height() while cs_main is locked

* Properly read and write lastChainLockBlock

"pindex" is NOT the chainlocked block after the while loop finishes. We
must use the pindex (renamed to pindexChainLock now) given on method entry.

Also, the GetLastChainLockBlock() result was not assigned to,
lastChainLockBlock which resulted in the while loop to run unnecessarily
long.

* Generalize filtering in NewPoWValidBlock and SyncTransaction

We're actually interested in all TXs that have inputs, so no need to
explicitly check for tx types.

* Use tx.IsCoinBase() instead of checking for index 0

* Handle cases where a TX is not received yet in wait_for_instantlock

* Wait on all nodes for the locks

Otherwise we end up with the sender having it locked but other nodes
not yet, failing the test.

3a1aeb000e Multiple fixes/refactorings for ChainLocks (#2765)
* Print which DKG type aborted

* Don't directly call EnforceBestChainLock and instead schedule the call

Calling EnforceBestChainLock might result in switching chains, which in
turn might end up calling signals, so we get into a recursive call chain.

Better to call EnforceBestChainLock from the scheduler.

* Regularly call EnforceBestChainLock and reset error flags on locked chain

* Don't invalidate blocks from CChainLocksHandler::TrySignChainTip

As the name of this method implies, it's trying to sign something and not
enforce/invalidate chains. Invalidating blocks is the job of
EnforceBestChainLock.

* Only call ActivateBestChain when tip != best CL tip

* Fix unprotected access of bestChainLockBlockIndex and bail out if its null

* Fix ChainLocks tests after changes in enforcement handling

* Only invoke NotifyChainLock signal from EnforceBestChainLock

This ensures that NotifyChainLock is not prematurely called before the
block is fully connected.

* Use a mutex to ensure that only one thread executes ActivateBestChain

It might happen that 2 threads enter ActivateBestChain at the same time
start processing block by block, while randomly switching between threads
so that sometimes one thread processed the block and then another one
processes it. A mutex protects ActivateBestChain now against this race.

* Rename local copy of bestChainLockBlockIndex to currentBestChainLockBlockIndex

* Don't call ActivateBestChain when best CL is part of the main chain

Send/Receive multiple messages as part of one P2P message in CSigSharesManager (#2729)
* Return bool in ProcessMessageXXX methods to indicate misbehaviour

* Send/Receive multiple messages as part of one P2P message in CSigSharesManager

Many messages, especially QSIGSHARESINV and QGETSIGSHARES, are very small
by nature (5-14 bytes for a 50 members LLMQ). The message headers are
24 bytes, meaning that we produce a lot of overhead for these small messages.
This sums up quite a bit when thousands of signing sessions are happening
in parallel.

This commit changes all related P2P messages to send a vector of messages
instead of a single message.

* Remove bogus lines

Included these by accident

* Unify handling of BanNode in ProcessMessageXXX methods

* Remove bogus check for fMasternodeMode

* Properly use == instead of misleading >= in SendMessages

f305cf77b6 Multiple fixes and optimizations for LLMQs and ChainLocks (#2724)
* Indicate success when signing was unnecessary

* Fix typo in name of LLMQ_400_60

* Move RemoveAskFor call for CLSIGs into ProcessNewChainLock

In case we got INV items for the same CLSIG that we recreated through
HandleNewRecoveredSig, (re-)requesting of the CLSIG from other peers
becomes unnecessary.

* Move Cleanup() call in CChainLocksHandler::UpdatedBlockTip up

We bail out early in a few situations from this method, so that Cleanup()
might not be called while its at the bottom.

* Bail out from CChainLocksHandler::UpdatedBlockTip if we already got the CLSIG

* Call RemoveAskFor when QFCOMMITMENT was received

Otherwise we might end up re-requesting it for a very long time when the
commitment INV was received shortly before it got mined.

* Call RemoveSigSharesForSession when a recovered sig is received

Otherwise we end up with session data in node states lingering around until
a fake "timeout" occurs (can be seen in the logs).

* Better handling of false-positive conflicts in CSigningManager

The old code was emitting a lot of messages in logs as it treated sigs
for exactly the same session as a conflict. This commit fixes this by
looking at the signHash before logging.

Also handle a corner-case where a recovered sig might be deleted between
the HasRecoveredSigForId and GetRecoveredSigById call.

* Don't run into session timeout when sig shares come in slow

Instead of just tracking when the first share was received, we now also
track when the last (non-duplicate) share was received. Sessios will now
timeout 5 minutes after the first share arrives, or 1 minute after the last
one arrived.

9f58690322 Avoid using ordered maps in LLMQ signing code (#2708)
* Implement and use SigShareMap instead of ordered map with helper methods

The old implementation was relying on the maps being ordered, which allowed
us to grab all sig shares for the same signHash by doing range queries on
the map. This has the disadvantage of being unnecessarily slow when the
maps get larger. Using an unordered map would be the naive solution, but
then it's not possible to query by range anymore.

The solution now is to have a specialized map "SigShareMap" which is
indexed by "SigShareKey". It's internally just an unordered map, indexed by
the sign hash and another unordered map for the value, indexed by the
quorum member index.

* Only use unordered maps/sets in CSigSharesManager

These are faster when maps/sets get larger.

* Use unorderes sets/maps in CSigningManager

This removes the burden on the message handler thread when many sig batches
arrive. The expensive part of deserialization is now performed in the sig
shares worker thread.

This also removes the need for the specialized deserialization of the sig
shares which tried to avoid the malleability check, as CBLSLazySignature does
not perform malleability checks at all.

* Store quorumHash of first mined commitment in evoDb

* Speed up CQuorumManager::ScanQuorums

This does 2 things:
1. Only call HasQuorum for blocks that are potentially a quorumBlockHash
   These are only blocks which are at index 0 of each DKG interval
2. Stop scanning for quorums when we get below the first block that
   contained a commitment. If no commitment was ever mined, we bail out
   immediately.

* Return result instead of {}

* Remove HasQuorum() call as GetQuorum already does this

* Remove unnecessary "if (!qc.IsNull()))"

* Allow sub-batch verification in CBLSInsecureBatchVerifier

* Implement batch verification of CDKGDebugStatus messages

* Use uint8_t for statusBitset in CDKGDebugMemberStatus and CDKGDebugSessionStatus

No need to waste one byte per member and per LLMQ type.

* Reserve 4k of buffer for CSerializedNetMsg buffer

Profiling has shown that a lot of time is spent in resizing the data
vector when large messages are involved.

* Remove nHeight from CDKGDebugStatus

This field changes every block and causes all masternodes to propagate
its status for every block, even if nothing DKG related has changed.

* Leave out session statuses when we're not a member of that session

Otherwise MNs which are not members of DKG sessions will spam the network

* Remove receivedFinalCommitment from CDKGDebugSessionStatus

This is not bound to a session and thus is prone to spam the network when
final commitments are propagated in the finalization phase.

* Add "minableCommitments" to "quorum dkgstatus"

* Hold cs_main while calling GetMinableCommitment

* Abort processing of pending debug messages when spork18 gets disabled

* Don't ask for debug messages when we've already seen them

"statuses" only contains the current messages but none of the old messages,
so nodes kept re-requesting old messages.
