Fix issues introduced with asynchronous signal handling (#3369)
* Introduce SynchronousUpdatedBlockTip signal

This version of UpdatedBlockTip mirrors the asynchronous behavior that we
had before the introduction of asynchronous signal handling.

* Fix tab spacing in validationinterface.cpp

* Invoke CDeterministicMNManager::UpdatedBlockTip from validation thread

It must be invoked synchronously as otherwise things become inconsistent.

* Call CActiveMasternodeManager::Init with block index

pindexNew in UpdatedBlockTip is not necessarily the current tip, so we
shouldn't rely on it in Init(). This is due to the async nature of the
UpdatedBlockTip invocation.

Various fixes for DSTX-es (#3295)
* Check MNs up to 24 blocks deep when verifying `dstx`

* Handle DSTX-es more like regular txes and not like "other" invs

* Try asking for a DSTX too when trying to find missing tx parents

* Check DSTX-es when chainlock arrives

`HasChainLock` was always `false` in `IsExpired` because tip is updated before the corresponding chainlock is received

* Apply `Handle DSTX-es more like regular txes` idea to `AlreadyHave()`

* Alternative handling of DSTX+recentRejects

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"

* Use cmd == nullptr instead of !cmd

* Remove last parameter from AvailableCoins call

Implement MNAUTH and allow unlimited inbound MN connections (#2790)
* Sort evo/* source files in Makefile.am

* Keep track of proRegTxHash in CConnman::masternodeQuorumNodes map

We will later need the proRegTxHash

* Fix serialization of std::tuple with const rvalue elements

Having serialization and deserialization in the same specialized template
results in compilation failures due to the "if(for_read)" branch.

* Implement MNAUTH message

This allows masternodes to authenticate themself.

* 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
connecting to the same MNs through intra-quorum connections.

* Apply review suggestions

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.
