Loop currently has a 5000ms sleep at the end so as to not overconsume
locks.

* Remove duplicate functions from rebase

* Fix assertion failure in mining/staking

Need to explicitely set pindexPrev and nHeight within the locked scope.

* Fixup coinspend unit test header includes

* Fix wrapped serial functional test

The error message had changed

* Remove security level in `DoZpivSpend()` call

* Disable precompute for functional tests

The locking can interfere with block generation

* Fixup the interface_rest functional test

* Better logging for CheckCoinSpend

Also re-introduce the regtest specific conditional

* Prevent lock spamming when no stakable inputs are present

* Cleanup arbitrary sleep times in CreateCoinStake

* Fixup bad logprintf

* fixup makefile.am

* Don't error out when a range has already been computed

When a range of blocks has already been computed, use that existing data
 instead of erroring out. This is used in the zPoS pipeline where, after
  precomputation, the passed `pindexCheckpoint` is likely to be at a
  block height below the accumulator's tip/end.

* Fix irrelevant receipt status message

Since security level has been removed, this status message needed to be
changed.

Also removed some stale unused code that was left over from when
security level was used.

* Reduce log spam

New debug category "staking" added with some previous `LogPrintf`
messages recategorized to reduce log spam.

Also noted both "staking" and "precompute" in the init help message and
added them to the "pivx" umbrella category.

* Don't return an invalid state when shutting down the wallet

When the shutdown process is started, it is possible that the call to
`ValidateAccumulatorCheckpoint()` in `ConnectBlock()` will fail. Instead
 of returning an invalid state, which causes the block to pass through
 `InvalidChainFound()`, just return a stateless error if a shutdown has
 been requested.

locked the message for all mints is that the seed is wrong. This commit
fixes it by replacing the message and stating that the locked wallet
prevents precomputation and spending.

* [Net] Add new checkpoints for mainnet/testnet

This adds two new checkpoints for mainnet:
 * Block 1679090 - first block with a wrapped serial
 * Block 1686229 - last block that zPIV was active

Also for testnet:
 * Block 1016800 - Arbitrary recent block

* [Qt] Prevent double deletion of progress dialog

When `showProgress()` is passed a `100` int value, the dialog is deleted
. If the function is passed a `100` int value a second time in the same
scope, like what happens at the end of `RecalculateZPIVSpent()` and
`RecalculateZPIVSupply()`, it results in a segfault.

This change standardizes the process by first initializing the progress
dialog with a `0` value, updating to a maximum of a `99` value inside
the loop, and finally closing with a `100` value after the loop has
completed.

7980f23c0c [RPC] fix fee calculation in 'getblockindexstats' and 'getfeeinfo' (random-zebra)
689ac23f62 [RPC] add 'getblockindexstats' function (random-zebra)

Pull request description:

  This introduces a new RPC method `getblockindexstats` to get aggregated BlockIndex data for a range of blocks:
  - transaction count
  - transaction count (including coinbase/coinstake txes)
  - zPIV per-denom mint count
  - zPIV per-denom spend count
  - total transaction bytes
  - total fees in block range
  - average fee per kB

  Since it expands the functionality of `getfeeinfo`, this method has been redirected to call `getblockindexstats` (over the **last** N blocks).

  To avoid code duplication with `getserials` and `getmintsinblocks`, the initial validation of the input params has been refactored in the function `validaterange()`.
  This also contains a fix to prevent the wallet from crashing when calling these functions over out-of-range blocks.

Travis was regularly failing because the full test suite with coverage
takestoo much time.
Bitcoin has some optimisations in there which allows them to give less
time to the test part of the process. We don't so until we do, we have
to reserve more time. We will probably have to restart manually more
travis jobs but that's the only way to have them run to the end.

Pull request description:

  Fixes https://github.com/PIVX-Project/PIVX/issues/960

  Rationale: the test result should be set only through `assert`s in the test and not rely on what's printed on the console. Furthermore, as shown in the issue, stderr could contain simple warnings that don't affect the test's outcome.
  If stderr is not empty though, print its content.

  Also re-sort tests by duration.

983d97a86c6450c85a0411eed5b533e3109c1aea [Refactor] Combine parameter checking of budget commands (Cave Spectre)

Pull request description:

  ### **Release notes**
  - [Refactor] Move common budget parameter checking code into a function

  ### **Details**
  The code in both `preparebudget` and `submitbudget` used the same parameter checking.  This pulls that parameter checking and loading into a common routine used by both; for ease of improvements and adjustments to the parameter checking... so the risk of not adjusting them consistently in both routines is removed.

  ### **Note**
  The early discussion below is based on a combined PR that addressed this, plus #950 and a PR to be named later.  The decision was made to split and focus; so the discussions can be independent of each other and refactor as needed.

* Merge #952: [Staking] Prevent potential negative out values during stake splitting

139d333dd9c294e13115bfd8e1b1a8d7ad1e9d2e Minting: Prevent potential negative out values (Cave Spectre)

Pull request description:

  On the rare occasion that a small UTXO wins a stake; and that user has (by lack of understanding, or by error) configured a very small StakeSplitThreshold; they can end up in a situation where their extremely lucky stake win fails at consensus because of the way the stake split is calculated.

  The logic split the block reward between the two outputs; along with the input.  However if that input is significantly small, and the block reward is significantly weighted to the masternode; then the potential for a negative (and thus very very large) output would be created in the second side of the split.  This is due to the fact that the full masternode reward is taken out of the "previous" output (`vout[i - 1]`).

  This is a rare, if not relatively impossible, scenario with PIVX at it's current state, but the potential grows much larger when coin parameters are re-arranged; e.g. small stakes with a heavy weight onto the masternode reward.  i.e. a stake split of 5, with a block reward of 10, and 90% to the masternode.   15 ends up split into vout[1] and vout[2], both receiving 7.5; yet FillBlockPayee will subtract 9 from vout[2]; resulting in a negative wrapped to a large positive.

  This logic simply puts the reward that will be deducted from into the second vout.  So with the above numbers; vout[1] is split to 2.5, vout[2] is initially 12.5 and then after the unknown (at that time) masternode fee of 9, is reduced to 3.5; no longer going negative.

  Of course this is an extreme example; but the potential still exists.

  Alternatively, restrictions could be placed on setstakesplitthreshold to prevent the user from setting a threshold dangerously low; or a minstake could be setup to prevent a stake small enough to be a problem from being considered.  However, this seems like the best solution to the problem; by handling it without adding a lot of logic to collect the chain parameters and set limits that make sense to whatever chosen configuration is used.

* Merge #971: [Wallet][zPIV] zc public spend parse crash in wallet startup.

12c44cafdeb49ec0b5fbe5815cb4fa431bc2a934 [Wallet][zPIV] zc public spend parse crash in wallet startup fixed. (furszy)

Pull request description:

  ### Crash Details
  Essentially the crash happens when the wallet.dat file contains a zc public spend transaction (input) and the user have removed the chain data.

  Specifically inside the `decomposeTransaction` in the `TransactionRecord` class the wallet tries to parse the `publicCoinSpend` looking for every output that is linked to the transaction, as there is no information about the output in disk, the wallet throws a runtime error on the startup blocking the initialization (only two ways to surpass this issue for current users:

  1) Download the snapshot.
  2) Start the wallet with another wallet.dat file and let it sync until the required output data is downloaded).

  --------
  ### Fix
  Use only the coin spend serial and not try to parse + validate the whole object, there is no need to do it there, if the transaction is in the internal wallet txes map then it means that it passed all of the validations.

  This adds a first basic functional test for the spork RPC.
  The spork key for RegTestNet is updated, and the relative private key is provided in the comment so anyone is able to test (prior to this, there was no public key set for RegNet so it inherited the TestNet value).

f7ac53b2d5de29951240718680443b62acfa6db2 [RPC] Correct issues with budget commands (Cave Spectre)

Pull request description:

  ### **Release notes**
  - [RPC] Fix potential wallet crashes in budget commands
  - [RPC] Remove unnecessary conditionals in parameter checking of budget commands

  ### **Details**
  **wallet segfault**
  `preparebudget`, invoked before the wallet has fully started, caused a segfault and crashed.  This was due to the lack of checking for `pwalletMain` before referencing cs_wallet.  This is solved with a throw error to tell the user to try again after the wallet has started.

  Furthermore; both `preparebudget` and `submitbudget` has a check for `pindexPrev` to conditionalize the assignment of nBlockMin (which references `pindexPrev->nHeight`); however later checks, `pindexPrev->nHeight` is referenced even if the pindexPrev check failed; which would have caused a crash if pindexPrev was NULL.  This would occur if `chainActive->Tip()` returns null.  Given the logic of `getnextsuperblock`, the check added to preparebudget and submitbudget will generate a throw error if there is no active chain tip.

  **Remove unnecessary conditionals and code**
  `pindexPrev` is loaded from `chainActive.Tip()` pindexPrev->nHeight is checked multiple times in the parameter checking.  For ease of reading, pindexPrev->nHeight is now saved in a variable as it is used multiple times in the execution of the RPC commands in question.  Likewise, two function calls are used to determine the constant length of a budget cycle `Params().GetBudgetCycleBlocks()`; and is used several times.  Storing this information in a constant is more efficient then several calls for the information.

  nBlockMin is determined (the next superblock).  However later nNext was defined to be the exact same thing.  It's not necessary to build them both.

  By nature of validating that the chosen budget cycle block is greater than the current block, and validating the number of cycles is greater than zero; the need to check the end of the budget cycle is unnecessary.

  Having a separate throw message for choosing the wrong block (not a budget block), and specifying a block that has passed is unnecessary.  These have been combined so that the user, putting in the wrong block, is informed, in both cases, what the next budget block is.

  ### **Note**
  This PR was originally part of #964, but split out to distinguish between these changes and the other's refactoring.

9294bbfd4629b2bacd62c9c4b55d92d248c0becc Modify GetNextWorkRequired to set Target Limit correctly on first PoS block (CaveSpectre11)

Pull request description:

  GetNextWorkRequired() was not setting the work required properly on the first Proof of Stake block.  The code section to cap the work at the bnTargetLimit wasn't called on that first block, but rather on the second Proof of Stake block.

  The end result is that the first PoS block uses the difficulty from the PoW, rather than capping it at the target limit; with the second PoS block capping it at the target limit:

  `uint256 bnTargetLimit = (~uint256(0) >> 24);`

  Creating a difficulty problem should the final PoW difficulty be greater than bnTargetLimit.

  ---
  This code has been tested on an altcoin; and I can provide debug output demonstrating the shift of the TargetLimit to 00000FFFF the block after the first PoS block should it be desired.
