1e62969fa6 Preparations for upcoming backport of Bitcoin #8580
Instead of deriving from CTransaction, we now have a CTransactionRef member
in CTxLockCandidate. This is needed for the next backported PR #8580,
which will make CTransaction immutable.

Also use CTransactionRef in CDarkSendEntry, CDarksendBroadcastTx and

753b1e486b Eliminate remaining uses of g_connman in Dash-specific code. (#1635)
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.

* InstandSend overhaul
- relay conflicting votes to detect attack earlier and PoSe-ban attacking masternode(s)
- cancel conflicting completed locks
- do not overwrite mempool or reprocess blocks
- 15 sec timeout/window to lock tx

* check nValueIn for SPORK_5_INSTANTSEND_MAX_VALUE (instead of nValueOut)

* relay valid vote asap

* ignore votes for spent coins, consider them invalid

60409df822 InstantSend overhaul (#1288)
* 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

- 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

- TXLOCKREQUEST should be processed as normal tx plus some custom logic, should not "fake" inventory
- should not create "fake" local lock, should instead keep track of orphan votes and reprocess them when corresponding TXLOCKREQUEST arrives
- orphan vote time map should be indexed by full outpoint, not by txid of mn collateral

785adad57e Slightly refactor/fix IS (#1153)
* slightly refactor IS:
- the only place where logic is changed: `ProcessTxLockVote()` - it should first try to find mn and fail if none was found and only then try to call `GetMasternodeRank()` (which is heavy)
- fixed few `cs_main`
- slightly optimized number of `tx.GetHash()` calls
- lots of `const` (fixed few related functions in main.cpp)
- few smaller fixes: iterators, log output, comments, etc
- use thread safe methods of mnodeman
- safety check in GetAverageUnknownVoteTime
