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.

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

0a5e8eb862 Move ChainLock signing into TrySignChainTip and call it periodically
Later commits will introduce checks for "safe TXs" which might abort the
signing on first try, but succeed a few seconds later, so we periodically
