4956ba7a7f Eliminate g_connman use in instantx module. (#1626)
Pass reference to CConnman instance to methods of CInstantSend
and other instantsend-related classes instead of using g_connman
global variable there.

* bump CMasternodeMan::SERIALIZATION_VERSION_STRING

* unify rank calculations even further

* fix (partially revert previous one)

84ecccefce InstandSend overhaul (#1592)
* InstandSend overhaul
- relay conflicting votes to detect attack earlier and PoSe-ban attacking masternode(s)

df6d458b85 Backport Bitcoin PR#9260: Mrs Peacock in The Library with The Candlestick (killed main.{h,cpp}) (#1566)
* Remove orphan state wipe from UnloadBlockIndex.

As orphan state is now "network state", like in
d6ea737be1,

UnloadBlockIndex is only used during init if we end up reindexing
to clear our block state so that we can start over. However, at
that time no connections have been brought up as CConnman hasn't
been started yet, so all of the network processing state logic is
empty when its called.

* Move network-msg-processing code out of main to its own file

* Rename the remaining main.{h,cpp} to validation.{h,cpp}

a9d771e497 Backport Bitcoin PR#8085: p2p: Begin encapsulation (#1537)
* net: move CBanDB and CAddrDB out of net.h/cpp

This will eventually solve a circular dependency

* net: Create CConnman to encapsulate p2p connections

* net: Move socket binding into CConnman

* net: move OpenNetworkConnection into CConnman

* net: move ban and addrman functions into CConnman

* net: Add oneshot functions to CConnman

* net: move added node functions to CConnman

* net: Add most functions needed for vNodes to CConnman

* net: handle nodesignals in CConnman

* net: Pass CConnection to wallet rather than using the global

* net: Add rpc error for missing/disabled p2p functionality

* net: Pass CConnman around as needed

* gui: add NodeID to the peer table

* net: create generic functor accessors and move vNodes to CConnman

* net: move whitelist functions into CConnman

* net: move nLastNodeId to CConnman

* net: move nLocalHostNonce to CConnman

This behavior seems to have been quite racy and broken.

Move nLocalHostNonce into CNode, and check received nonces against all
non-fully-connected nodes. If there's a match, assume we've connected
to ourself.

* net: move messageHandlerCondition to CConnman

* net: move send/recv statistics to CConnman

* net: move SendBufferSize/ReceiveFloodSize to CConnman

* net: move nLocalServices/nRelevantServices to CConnman

These are in-turn passed to CNode at connection time. This allows us to offer
different services to different peers (or test the effects of doing so).

* net: move semOutbound and semMasternodeOutbound to CConnman

* net: SocketSendData returns written size

* net: move max/max-outbound to CConnman

* net: Pass best block known height into CConnman

CConnman then passes the current best height into CNode at creation time.

This way CConnman/CNode have no dependency on main for height, and the signals
only move in one direction.

This also helps to prevent identity leakage a tiny bit. Before this change, an
attacker could theoretically make 2 connections on different interfaces. They
would connect fully on one, and only establish the initial connection on the
other. Once they receive a new block, they would relay it to your first
connection, and immediately commence the version handshake on the second. Since
the new block height is reflected immediately, they could attempt to learn
whether the two connections were correlated.

This is, of course, incredibly unlikely to work due to the small timings
involved and receipt from other senders. But it doesn't hurt to lock-in
nBestHeight at the time of connection, rather than letting the remote choose
the time.

* net: pass CClientUIInterface into CConnman

* net: Drop StartNode/StopNode and use CConnman directly

* net: Introduce CConnection::Options to avoid passing so many params

* net: add nSendBufferMaxSize/nReceiveFloodSize to CConnection::Options

* net: move vNodesDisconnected into CConnman

* Made the ForEachNode* functions in src/net.cpp more pragmatic and self documenting

* Convert ForEachNode* functions to take a templated function argument rather than a std::function to eliminate std::function overhead

* net: move MAX_FEELER_CONNECTIONS into connman

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

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
