* Multi-quorum InstantSend, complete refactoring + cleanup for IS and partial protobump * more changes: - allow InstantSend tx to have 10 inputs max - store many unique tx hashes in mapVotedOutpoints - more checks in AcceptToMemoryPoolWorker (moved from ProcessMessage + CTxLockRequest(tx).IsValid() ) * More changes: - let multiple lock candidates compete for votes - fail to vote on the same outpoint twice early * More changes: - notify CInstantSend on UpdatedBlockTip -> remove cs_main from CheckAndRemove() - notify CInstantSend on SyncTransaction -> count expiration block starting from the block corresponding tx was confirmed instead of the block lock candidate/vote was created - fixed few locks * add comments about nConfirmedHeight * Fix "Block vs Lock" edge case * Fix "Block vs Lock" edge case, p2 * Fix issues: - fix logic for locking inputs and notifying - see UpdateLockedTransaction, TryToFinalizeLockCandidate - add missing hash inserting in ProcessTxLockVote - add nMaxBlocks param to ResolveConflicts to limit max depth allowed to disconnect blocks recursively - fix false positive mempool conflict - add missing mutex locks - fix fRequireUnspent logic in CTxLockRequest::IsValid
