* 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)
* Clear votes which were created before spork15 activation
* Reject incoming votes which were created pre-DIP3
* Only use voting keys for VOTE_SIGNAL_FUNDING
The other vote signals are meant to be emitted by sentinel and must thus
be signed with the operator key.
* Simplify GetMinVoteTime
* Review suggestions/fixes
* Add missing mutex in CGovernanceObject::RemoveOldVotes
* Drop CInstantSend::IsEnoughOrphanVotesForTxAndOutPoint
* small cleanup in rpc tests
* move some pieces from .h to .cpp
* fix few log outputs
* fix some comments
* some trivial fixes + readability
* CacheMap::Insert should not update existing item, should return `false`
* Use `emplace` operator instead of `[]` to add new items in Cache*Map implementation
* Use prefix cm/cmm for CacheMap/CacheMultiMap maps respectively to distinguish them from each other and from std::map-s
* Avoid excessive processing of already known valid votes
Also prettify debug log output a bit
* Drop nCurrentSize from Cache*Map classes
Use `size()` and `empty()` of std classes instead, they have constant complexity since c++11
* Do not create an explicit iterator if it's never used later (in Cache*Map)
* Do not prune last item in CacheMultiMapInsert when trying to insert a duplicate one
0729102 Net: pass interruptMsgProc as const where possible (Jorge Timón)
fc7f2ff Net: Make CNetMsgMaker more const (Jorge Timón)
d45955f Net: CConnman: Make some methods const (Jorge Timón)
This monstrous change eliminates all remaining uses of
g_connman global variable in Dash-specific code.
Unlike previous changes eliminating g_connman use
that were isolated to particular modules, this one covers
multiple modules simultaneously because they are so interdependent
that change in one module was quickly spreading to others.
This is mostly invariant change that was done by
* changing all functions using g_connman to use connman argument,
* changing all functions calling these functions to use connman argument,
* repeating previous step until there's nothing to change.
After multiple iterations, this process converged to final result,
producing code that is mostly equivalent to original one, but passing
CConnman instance through arguments instead of global variable.
The only exception to equivalence of resulting code is that I had to
create overload of CMasternodeMan::CheckAndRemove() method without arguments
that does nothing just for use in CFlatDB<CMasternodeMan>::Dump() and
CFlatDB<CMasternodeMan>::Load() methods.
Normal CMasternodeMan::CheckAndRemove() overload now has argument of
CConnman& type and is used everywhere else.
The normal overload has this code in the beginning:
if(!masternodeSync.IsMasternodeListSynced()) return;
Masternode list is not synced yet when we load "mncache.dat" file,
and we save "mncache.dat" file on shutdown, so I presume that it's OK
to use overload that does nothing in both cases.

* Store masternodes in a map instead of a vector, drop unused functions in CMasternodeMan
* CTxIn vin -> COutPoint outpoint
* do not use CMasternodeMan::Find outside of the class
* update GetMasternodeInfo
* safe version of GetNextMasternodeInQueueForPayment
* fix ProcessMasternodeConnections
* bump CMasternodeMan::SERIALIZATION_VERSION_STRING
* fixed an issue with MasternodeRateCheck always returns true
* additioanal fixes and refactoring (rebase)
* slightly improved CRateBuffer synchronization for newly started nodes
* fix vulnerability with mapMasternodeOrphanObjects
The vulnerability is that a malicious node can send a lot of NetMsgType::MNGOVERNANCEOBJECT messages which refer to many arbitrary MN's. In this case, mapMasternodeOrphanObjects will grow unrestrictedly.
* MN collateral moved to governance-object.cpp; ban score applied to misbehaving nodes
* recursive locks removed
* check for the mn collateral code segregated to a separate function
* CheckCollateral implementation moved to cpp
* fix issues with mapSeenGovernanceObjects
Removed seen-governance-objects optimization except for deleted objects. Otherwise some nodes can permanently lost proposals if they received them too early.
Beside of that there is a vulnerability with seen-governance-objects mechanism if malicious node send us a lot of invalid governance objects.
* mapSeenGovernanceObjects renamed to mapErasedGovernanceObjects
* current fixes
* use int64_t for expiration timestamp
* process governance objects in CheckMasternodeOrphanObjects as usual
* code refactoring: SetRateChecksHelper class added
* fixed race condition issues with propagation of governance objects
* change GetCollateralConfirmations signature
* code refactoring
* reduced minimum number of collateral confirmations required for relaying proposals
* bug fixes and improvements
* Implement RequestOrphanObjects
* Ensure governance objects are only requested from peers once per call
* Add gobject log messages
* Implemented CleanOrphanObjects
* Move governance maintenance functions from NewBlock to a time-based function
* Remove unused delcaration for mapAskedForGovernanceObject
* Only accept wd's that are more recent or have a higher hash than the current best
* Fix whitespace typo
* Relay current watchdog when lower priority ones are received
* Fix nHashWatchdogCurrent reset conditions
* expire previous current wd when a new one is found in UpdateCurrentWatchdog
* fail to process votes for expired or deleted object
* Add "enough data" stop conditions for gov sync
* fix:
- make sure condition is checked only once per tick
- let condition be fully used on resync (reset nTimeNoObjectsLeft)
* On gov sync first sync objs, then ask for votes on per-obj basis from different peers.
This should help to sync obj list initially and split the load among many peers. Also adds ability to catch up votes later after the sync.
* ask for all objects, do this in cycles
* Fix Sync() code, better readability
* ask multiple nodes at once when possible, perf boost for large numper of objs
* Addressed comments: pass reference, more peer version check
- some were not used, some were included twice, some were in the wrong place, some were missing (but it compiled because some were in the wrong place)
- organized a bit better, grouped dash specific includes in original bitcoin files, should save some time solving conflicts when/if merging patches later
* Change rate check logic to avoid DoS attacks
* Convert rate check to use object timestamp instead of arrival time
* Update cached variables before checking for superblocks
* Ensure that last times are monotonically non-decreasing
* Bump governance manager serialization format
* Improved rate check error reporting
* Vote relaying changes
- Remove vote relaying from ProcessVote
- Remove vote relaying from orphan vote processing
- Relay vote in ProcessMessages (only)
* Do not relay governance objects during orphan processing
* Restore relaying of local votes
* Changed overloaded function name: ProcessVote->ProcessVoteAndRelay
* locks in PS

* LOCK(cs) is not needed here
* Decouple governance init actions from serialization
Should fix this:
```
Assertion failed: lock governance.cs not held in governance-classes.cpp:117; locks held:
cs_Shutdown init.cpp:200 (TRY)
cs ./governance.h:195
cs governance.cpp:835
Abort trap: 6
```
* Increase quorum for object deletion to 2/3 of MN network
* Implement expiration of watchdog objects
* Remove objects from the watchdog map itself
* Message fix for invalid objects
