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

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.
