* 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)
* Few networking fixes:
- skip "masternode"/inbound connections for sync related processes
- do not sync gov data to other nodes until fully synced ourselves
- do not accept incoming connections until fully synced
* inbound connections could be harmful only if our node is a masternode
* same for CGovernanceManager::Sync
* 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
* Store time we saw mnb last time, bump sync timeout
if we received seen mnb but we are too close to MASTERNODE_NEW_START_REQUIRED_SECONDS
* Reset blockchain sync status if new blocks were accepted during sync
* Add some debug log output
* wait for at least one new block to be accepted
* bump CGovernanceManager-Version
* locks in PS
* lock in governance
* locks in IS
* lock in ProcessGetData
* locks in CMasternodeSync
* centralize mnodeman.Check call
* locks order in mnpayments
* use current block chainTip when possible (less locks)
* add missing lock in CountInputsWithAmount
* fix deadlock RequestLowDataPaymentBlocks/IsTransactionValid
* LOCK2 in CheckMnbAndUpdateMasternodeList, CheckAndUpdate, SendVerifyRequest
* 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
```

Followup for the recent winner_block PR (#1028) and name confusion discovered during code review.
"Mostly" because also:
- CMasternodeBlockPayees::GetPayee -> CMasternodeBlockPayees::GetBestPayee which describes what this function is actually doing a bit better imo;
- fixing constructor CMasternodePaymentVote empty constructor
* store vote hashes in CMasternodePayee and use them in CMasternodePayments::Sync
* Request low data payment blocks in batches directly from some node instead of/after preliminary Sync.
* remove nVotes
da406e3 Masternode sync improvements
- add simple helpers for few more sync states (use them where appropriate instead of old code + rpc output)
- use new helpers to avoid meaningless message processing
- actually fail if sync shouldn't continue due to lack of info, make sure Reset is used to quit failed state
068c178 Added DBG macro in util.h to facilitate debugging
- This macro allows debugging statements (typically printf's or cout's) to
be activated or deactivated with a single comment. Uncomment the line:
//#define ENABLE_DASH_DEBUG
in util.h to enable debugging statements.
- When commented any code wrapped with the DBG() macro will simply be removed
by the preprocessor. When not commented all such wrapped statements will
be present.
- For maximum effectiveness it is best that util.h be the first effective include
in all source files. It is also possible to enable the macro for a single file
by temporarily adding #define ENABLE_DASH_DEBUG to the top of the file.
- Code committed to non-development branches should always have the define
commented.
d125d9b V0.12.1.x -- merging trigger/generic object/superblock changes for testnet phase II
- This commit contains the core governance system changes for 0.12.1. Any unrelated
changes have either been removed or moved to separate commits.
120724c File mode fixes
- Changed mode 0755->0644 on several source files.
c7f9e11 Updated todo reminders
- Added reminder to revert temporary reduction of number of votes
required to trigger superblock to 1 for testing
92adc98 Made CSuperblockManager::IsValidSuperblockHeight an inline function
- This is for efficiency since this function is called often and is
only 1 line of code.
c050ed7 Added comment explaining rationale for no LOCK(cs) in CSuperblock::IsValid
dc933fe Removed unused CSuperblockManager::IsBlockValid function
decec88 Moved calls to SuperblockManager::IsValidSuperblockHeight into IsSuperblockTriggered.
- Since calls to the later function are always protected by the former there's
no reason to keep these separate and this simplifies the code in
masternode-payments.cpp.
8672885 Reestablished expected value check for non-superblocks in IsBlockValueValid
b01cbe0 Changes to IsBlockValueValid to fix rpc test failure
a937c76 Changed include order to allow per file activation of the DBG macro
d116aa5 Fixed IsValidSuperblockHeight logic
- Note this has an effect on testing because we can now only create
1 superblock per day. Devs may need to temporarily change testnet params
for easier testing.
2d0c2de Convert superblock payments to CAmount
- We assume that payment values in JSON are in units of DASH
for consistency with other RPC functions, such as
createrawtransaction.
376b833 Revert temporary testing value for nAbsVoteReq
- Also ensure that number of votes required is never smaller than 1
8c89f4b Cleaned up CSuperblock error handling
- Exceptions are now thrown consistently rather than using a mix of
exceptions and return code checking. Exceptions are now caught only
in AddNewTrigger when the CSuperblock constructor is called. Unnecessary object
status members have been removed.
d7c8a6b Removed utilstrencodings header
- This appears to help with travis tests, for unknown reasons.
c4dfc7a Fixed some minor code review issues
63c3580 Reverted locking change in miner.
- This should have been done in the original PR but was overlooked.
4ab72de Fixed variable name to match common practice and bracket formatting
886a678 Improvements to vote conversion code
- Replaced redundantly defined function with inclusion of governance-vote.h
- Replaced magic numbers with their corresponding constant symbols
0a37966 Reordered governance message handling

+ decouple from util.h and version.h
+ more functions for CDarksendBroadcastTx: constructors, signing, serialization
+ move from rand() to insecure_rand() in general but to GetRand() for session id
+ fix defaults
