* 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
