Replaced references to Namecoin with Dogecoin
Set chain ID when constructing a new block to be mined
Added assignment overload so that assigning one BlockVersion to another does a full copy.
Changed AuxPoW parent block hashing to use Scrypt rather than SHA256 hash.
Update chain parameters to match Dogecoin
Move CheckProofOfWork into dogecoin.cpp and rename it to CheckAuxPowProofOfWork.
Add operator overrides to CBlockVersion so that naive usage operates on the underlying version without chain ID or flags.
Modify RPC mining to more closely match existing submitblock() structure

Changes are as below:
Wrap CBlockHeader::nVersion into a new class (CBlockVersion). This allows to take care of interpreting the field into a base version, auxpow flag and the chain ID.
Update getauxblock.py for new 'generate' RPC call.
Add 'auxpow' to block JSON.
Accept auxpow as PoW verification.
Add unit tests for auxpow verification.
Add check for memory-layout of CBlockVersion.
Weaken auxpow chain ID checks for the testnet.
Allow Params() to overrule when to check the auxpow chain ID and for legacy blocks. Use this to disable the checks on testnet.
Introduce CPureBlockHeader.
Split the block header part that is used by auxpow and the "real" block header (that uses auxpow) to resolve the cyclic dependency between the two.
Differentiate between uint256 and arith_uint256.
This change was done upstream, modify the auxpow code.
Add missing lock in auxpow_tests.
Fix REST header check for auxpow headers.
Those can be longer, thus take that into account. Also perform the check actually on an auxpow header.
Correctly set the coinbase for getauxblock results.
Call IncrementExtraNonce in getauxblock so that the coinbase is actually initialised with the stuff it should be. (BIP30 block height and COINBASE_FLAGS.)
Implement getauxblock plus regression test.
Turn auxpow test into FIXTURE test.
This allows using of the Params() calls.
Move CMerkleTx code to auxpow.cpp.
Otherwise we get linker errors when building without wallet.
Fix rebase with BIP66.
Update the code to handle BIP66's nVersion=3.
Enforce that auxpow parent blocks have no auxpow block version.
This is for compatibility with namecoind. See also https://github.com/namecoin/namecoin/pull/199.
Move auxpow-related parameters to Consensus::Params.
AcceptBlock will no longer process an unrequested block, unless it has not
been previously processed and has more work than chainActive.Tip()
Github-Pull: #5875
Rebased-From: 9be0e6837b878f72bd087ce32b7a2f2ffb2fd544
Ever since #5957 there has been the problem that older RPC test cases
(as can be found plenty in open pulls) use setgenerate() on regtest,
assuming a different interpretation of the arguments. Directly
generating a number of blocks has been split off into a new method
`generate` - however using `setgenerate` with the previous arguments will
result in spawning an unreasonable number of threads, and well, simply
not work as expected without clear indication of the error.
Add an error to point the user at the right method.
This reverts commit e2edf95cd3f43331843676e49a82830128a95050 6b04508e37c5dd18cec1cd61cc4356bd208aa991 0df67f1f7ab4adfe9f0b3ba6276e737b37826464,
except the changes to the RPC tests.
A `generate` RPC call is introduced based on the old code.
Rebased by @laanwj:
- update for RPC methods added since 84d13ee: setmocktime,
invalidateblock, reconsiderblock. Only the first, setmocktime, required a change,
the other two are thread safe.
Speed up generating blocks in regression test mode, by moving
block-creating and nonce-finding directly into the setgenerate
RPC call (instead of starting up a mining thread and waiting for
it to find a block).
This makes the forknotify RPC test three times quicker, for
example (10 seconds runtime instead of 30 seconds, assuming
the initial blockchain cache is already built).
1bea2bb Rename ProcessBlock to ProcessNewBlock to indicate change of behaviour, and document it (Luke Dashjr)
d29a291 Rename RPC_TRANSACTION_* errors to RPC_VERIFY_* and use RPC_VERIFY_ERROR for submitblock (Luke Dashjr)
f877aaa Bugfix: submitblock: Use a temporary CValidationState to determine accurately the outcome of ProcessBlock, now that it no longer does the full block validity check (Luke Dashjr)
24e8896 Add CValidationInterface::BlockChecked notification (Luke Dashjr)
