Better error handling while processing special txes (#3504)
* Return invalid state for GetTxPayload failures instead of asserting

* Throw an error when internal `find` fails instead of asserting

* Unify mnlist checks for lists created from blocks and lists created via updates of older lists with diffs

* Wrap evo block processing in try..catch to make sure all earlier introduced throws are caught

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

07620746a5 Implement GetMined(AndActive)CommitmentsUntilBlock and use it in ScanQuorums
This fixes a bug in ScanQuorums which made it return quorums which were not
mined at the time of pindexStart. This was due to quorumHashes being based
on older blocks (the phase=0 block) which are ancestors of pindexStart even
if the commitment was actually mined in a later block.

GetMinedAndActiveCommitmentsUntilBlock is also going to be used for quorum
commitment merkle roots in CCbTx.

This also removes GetFirstMinedQuorumHash as it's not needed anymore.

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.

03fa115503 Speed up CQuorumManager::ScanQuorums (#2677)
* Store quorumHash of first mined commitment in evoDb

This allows to skip scanning for quorums below this block.

* 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()))"

It's already checked at the top of the loop

* When necessary, remove DB_FIRST_MINED_COMMITMENT from evoDb in UndoBlock

18950f923e Optimize DKG debug message processing for performance and lower bandwidth (#2672)
* 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.

As described in https://github.com/dashpay/dips/pull/31 (see discussion).

* Properly ban nodes for invalid commitments

Implement and enforce DIP6 commitments (#2477)
* Add LLMQ parameters to consensus params

* Add DIP6 quorum commitment special TX

* Implement CQuorumBlockProcessor which validates and handles commitments

* Add quorum commitments to new blocks

* Propagate QFCOMMITMENT messages to all nodes

* Allow special transactions in blocks which have no inputs/outputs

But only for TRANSACTION_QUORUM_COMMITMENT for now.

* Add quorum commitments to self-crafted blocks in DIP3 tests

* Add simple fork logic for current testnet

This should avoid a fork on the current testnet. It only applies to the
current chain which activated DIP3 at height 264000 and block
00000048e6e71d4bd90e7c456dcb94683ae832fcad13e1760d8283f7e89f332f.

When we revert the chain to retest the DIP3 deployment, this fork logic
can be removed again.

* Use quorumVvecHash instead of quorumHash to make null commitments unique

Implementation of https://github.com/dashpay/dips/pull/31

* Re-add quorum commitments after pruning mempool selected blocks

* Refactor CQuorumBlockProcessor::ProcessBlock to have less nested if/else statements

Also add BEGIN/END markers for temporary code.

* Add comments/documentation to LLMQParams

* Move code which determines if a commitment is required into IsCommitmentRequired

This should make the code easier to read and also removes some duplication.

The also changes the error types that are possible from 3 to 2 now. Instead
of having "bad-qc-already-mined" and "bad-qc-not-mining-phase", there is
only "bad-qc-not-allowed" now.

* Use new parameter from consensus parames for the temporary fork
