* Remove code for QDEBUGSTATUS propagation

This turned out to be too expensive and could easily take the network
down by bringing all nodes to 100% CPU usage. Better to fully remove this
functionality.

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
retry to sign the tip.

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.

Implement CDummyDKG and CDummyCommitment until we have the real DKG merged (#2492)
* Add SPORK_17_QUORUM_DKG_ENABLED spork

* Implement CDummyDKG and CDummyCommitment until we have the real DKG merged

This is only used on testnet/devnet/regtest and will NEVER be used on
mainnet. It is NOT SECURE AT ALL!

See comment in quorums_dummydkg.h for more details.

* Test simple PoSe in DIP3 tests

* Generate 2 instead of 4 blocks per iteration in PoSe tests

4 was based on old chainparams where I used larger phases.

* Only sleep when necessary in PoSe tests

* Fix typo in comment

* Give PoSe tests more time and sync after fast-forward

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
