* 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 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
```

* Implemented several governance changes
- Limit strData size to avoid propagation of very large messages
- Remove unused CGovernanceObject::SetData method
- Remove CGovernanceObject::strName field to avoid data redundancy
* Fixed parameter count bug in gobject prepare
* Remove unnecessary call to IsCollateralValid and hence allow superblocks
to propagate
* Added CMasternodeMan::Get overload for masternode vin
* Use vin as masternode identifier instead of public key
* Fixed missing member in copy constructor, improved logging
* Added logging for MasternodeRateCheck failures
* Removed pubkeyMasternode field from CGovernanceObject
* Impose MN trigger creation rate limit only when MN info is synced
* Improve rpcgovernance error handling
- Prevent attempts to prepare trigger objects (and waste the collateral)
- Improve clarity of gobject submit error messages
* trivial governance cleanup:
- spaces
- names
- no "using namespace std;"
- few log and rpc messages adjusted
- remove unused
- use defined types
- move few members to private
* fixing after code review
* Improved exception handling
- Removed attempts to catch exceptions in intermediate helper function calls
- Made helper functions for JSON parsing private
* Governance voting fixes
- Converted voting defines to enums for better type safety
- Enabled gobject voteraw rpc command
- Removed unused parameter from gobject getvotes rpc command
* Fixed help message for gobject get
* Improved encapsulation of CGovernanceVote objects
- CGovernanceVote data members are now private
- Necessary to ensure that enum values are used for signals and outcomes since data members remain int's for compatibility with serialiation code

for invalid strings

* Modified GetBudgetSystemCollateralTX to take fee amount parameter
* Changes due to code review comments
- Naming changes
- Removed confusing comment
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

390c9c3 add dirty flag for future use
b76304e added other cached flags into output
487674f Governance object/vote syncing fixes
- disable fCached values
- use two maps for storing votes, by hash and parent-hash/type
- disable part of flatdb.dump (still overwriting)
- fixed govobj/votes relay and sync
15821fe various fixes
- Added const where possible
- Uncommented sync block
- Protocol min 70201
- Fixed bug which flags invalid votes incorrectly
- Formatting
aa8fdd7 fix curly braces
d8e39b1 Fix GetTypeHash bug
- Should not collide based on the outcome
732a8a3 fixed mismatched index for vote map
- Terrible bug which caused governance objects to have their hashes corrupted, causing objects to become invalid
- More proposal -> governance name changes
