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.

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.

84ecccefce InstandSend overhaul (#1592)
* 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

bd3978fd4b Fix IS vote expiration/cleanup: (#1316)
- vote should be removed when corresponding orphan vote expires
- fix CInstantSend::SyncTransaction: mapTxLockVotes is indexed by vote hash, not by tx hash (use votes from candidates and from orhpan vote map to avoid looping through the whole vote map)

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

a0c93ebaa5 cleanup/fix includes: (#1214)
- 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

470239bbc5 Fix IS: (#1161)
- 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

7f89bba83e Refactor InstantSend to use block count instead of local time to set expiration limit - nInstantSendKeepLock. Also make it (and number of blocks to reprocess in case of a conflict) a part of Consensus params and set it to lower numbers for testnet/regtest to be able to break things easier there.

8187228be1 Fixed budget syncing issues / forking issues / syncing issues
- Budgets now store the seen objects locally so they're not overwritten when saving/loading to check validity of budget.dat
- Added safer sync "failure" mode, that will retry an hour later if the sync fails for some reason. This will stop the client from thinking it has budget data and rejecting blocks when they're valid.

- Ask for up to 2 cycles of history

c701839a43 Proposal Security Overhaul
Submissions to the network now require a fee to be paid to the network (mining fee) using a special transaction with a OP_RETURN && ProposalHash in one of the outputs. This allows the network to filter spam quickly, while also allowing anyone to submit a proposal to the network.

To implement these changes we've introduced a few new commands:

mnbudget prepare PROPOSAL-NAME URL PAYMENT_COUNT BLOCK_START DASH_ADDRESS DASH_AMOUNT YES|NO|ABSTAIN [USE_IX(TRUE|FALSE)]
- To create the special transaction

mnbudget submit PROPOSAL-NAME URL PAYMENT_COUNT BLOCK_START DASH_ADDRESS DASH_AMOUNT YES|NO|ABSTAIN FEE_TX
- After the transaction is accepted by the network and has 3 confirmations, you can submit the transaction to the network here

mnbudget show
- Get the proposal hash from here

mnbudget vote PROPOSAL-HASH YES|NO|ABSTAIN
- You can now simply vote by hash using this command
