3b606b0c63 Merge #951: More block validation for governance (#951)
b6b6d6c Added nSuperblockStartBlock, adjusted testnet/regtest params

15a3c64 More for governance block checks, p1 (non-compilable):
    - add GetPaymentsLimit() and GetPaymentsTotalAmount()
    - IsValidBlockHeight() should check nSuperblockStartBlock
    - CSuperblock::IsValid should check payment limit and miner payout
    - no cs_main
    - slightly refactored related things

e8f9e5d More for governance checks, p2 (compilable):
    - IsBlockValueValid(), IsBlockPayeeValid() and FillBlockPayee() rewritten, no cs_main for them
    - CreateNewBlock adjusted, need more work on CBlockTemplate (see TODO)
    - moved (and simplified) IsBlockPayeeValid() call from CheckBlock() to ConnectBlock()

51434cf Add ability to calculate only superblock part of subsidy in GetBlockSubsidy()

aa74200 Fix GetPaymentsLimit()

de7b2b6c51 Merge #944: V0.12.1.x governance pr - part 1 - base functionality
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

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.

e8d9aabb62 Move many hardcoded mainnet/testnet magic numbers to consensus part of chainparams,
get rid of most `if(Params().NetworkIDString() == CBaseChainParams::MAIN)` and alike to unify formulas.
Further improvements will require testnet restart (see TODO notes in changed code) so I'm keeping few things as they are till then.

eece63fa72 Switch blocks to a constant-space Merkle root/branch algorithm.
This switches the Merkle tree logic for blocks to one that runs in constant (small) space.
The old code is moved to tests, and a new test is added that for various combinations of
block sizes, transaction positions to compute a branch for, and mutations:
 * Verifies that the old code and new code agree for the Merkle root.
 * Verifies that the old code and new code agree for the Merkle branch.
 * Verifies that the computed Merkle branch is valid.
 * Verifies that mutations don't change the Merkle root.
 * Verifies that mutations are correctly detected.

e4e5334ef8 Restore MedianTimePast for locktime.
Revert "Revert "Add rules--presently disabled--for using GetMedianTimePast as endpoint for lock-time calculations""
This reverts commit 40cd32e835.

After careful analysis it was determined that the change was, in fact, safe and several people were suffering
momentary confusion about locktime semantics.

40cd32e835 Revert "Add rules--presently disabled--for using GetMedianTimePast as endpoint for lock-time calculations"
This reverts commit 9d55050773.

As noted by Luke-Jr, under some conditions this will accept transactions which are invalid by the network
 rules.  This happens when the current block time is head of the median time past and a transaction's
 locktime is in the middle.

This could be addressed by changing the rule to MAX(this_block_time, MTP+offset) but this solution and
 the particular offset used deserve some consideration.

9d55050773 Add rules--presently disabled--for using GetMedianTimePast as endpoint for lock-time calculations
The lock-time code currently uses CBlock::nTime as the cutoff point for time based locked transactions. This has the unfortunate outcome of creating a perverse incentive for miners to lie about the time of a block in order to collect more fees by including transactions that by wall clock determination have not yet matured. By using CBlockIndex::GetMedianTimePast from the prior block instead, the self-interested miner no longer gains from generating blocks with fraudulent timestamps. Users can compensate for this change by simply adding an hour (3600 seconds) to their time-based lock times.

If enforced, this would be a soft-fork change. This commit only adds the functionality on an unexecuted code path, without changing the behaviour of Bitcoin Core.
