* Remove CActiveLegacyMasternodeManager
* Remove sentinelping RPC
* Remove unused P2P messages and inv types
There are still places where these are used in the code. The next commits
will clean these up.
* Remove MNB/MNP/MNVERIFY related code from masternode(man).h/cpp
* Remove all legacy code regarding block MN payee voting
* Remove MASTERNODE_SYNC_LIST and MASTERNODE_SYNC_MNW states
Also replace all uses of IsMasternodeListSynced and IsWinnersListSynced
with IsBlockchainSynced.
* Remove unsupported masternode RPCs
* Remove UpdateLastPaid methods
* Remove duplicate deterministicmns.h include
* Remove masternode.conf support
* Remove legacy MN lists support from masternode list GUI
* Remove unnecessary AskForMN call
* Remove compatibility code in CPrivateSendQueue::GetSignatureHash
* Don't add locally calculated MN payee in case GetBlockTxOuts failed
This is not valid in DIP3 mode
* Remove check for IsDeterministicMNsSporkActive in "masternode status"
* Move CMasternode::IsValidNetAddr to CActiveDeterministicMasternodeManager
* Remove use of CMasternode::CheckCollateral in governance code
* Remove uses of MASTERNODE_SENTINEL_PING_MAX_SECONDS/MASTERNODE_SENTINEL_PING_MAX_SECONDS
* Remove support for "-masternodeprivkey"
* Remove pre-DIP3 vote cleanup
* Remove compatibility code for quorumModifierHash/masternodeProTxHash
* Remove check for invalid nBlockHeight in CMasternodePayments::GetBlockTxOuts
...and let it crash instead. We expect this method to be called with the
correct height now (after DIP3 was fully deployed).
* Remove ECDSA based Sign/CheckSignature from CGovernanceObject
Only masternodes sign governance objects, so there is no need for ECDSA
support here anymore.
* Always add superblock and MN reward payments into new block
* Always check block payees (except if fLiteMode==true)
* Always allow superblock and MN payees in same block
* Remove/Fix a few references to masternode.conf and related stuff
Also delete guide-startmany.md and masternode_conf.md
* Implement NotifyMasternodeListChanged signal and call governance maintenance
* Remove non-DIP3 code path from CMasternodeMan::Find
* Remove remaining unused code from CMasternode/CMasternodeMan
* Always load governance.dat on startup
* Mine an empty block instead of incrementing nHeight from chain tip in miner tests
This test is crashing otherwise in GetBlockTxOuts as it tries to access a
previous block that is not existing.
* Skip MN payments verification on historical blocks (pre-DIP3 blocks)
Even though DIP3 was active on BIP9 level, the spork was not active yet at
that point meaning that payments were not enforced at that time.
* Remove unused state and CollateralStatus enums
* Unconditionally return false from IsBlockPayeeValid when IsTransactionValid returns false
IsTransactionValid already handles the case where IsDIP3Active() returns
false, making it return true.
* Add override keyword to CDSNotificationInterface::NotifyMasternodeListChanged
* Fix help for masternodelist status (POSE_BANNED and no OUTPOINT_SPENT)
