This is an ideal version of what the release process should look like,
making it more consistent with the OS X process. Some of the changes
described here would need to be made in the descriptors, which is somewhat
beyond what I would feel comfortable doing, not really understanding the signature process in depth.

This prevents an edge case where a block downloaded and pruned
in-between successive calls to FindNextBlocksToDownload could
cause the block to be unnecessarily re-requested.

- fixes#3136
- the problem is related to Boost path and a static initialized internal
pointer
- using a std::string in CDBEnv::EnvShutdown() prevents the problem
- this removes the boost::filesystem::path path field from CDBEnv

Move from sourceforge to linux foundation.
Also get rid of some other stale mentions of sourceforge.

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.
Add Scrypt hash and AuxPoW header to index database so that index can be validated
(a check that both Litecoin and Namecoin disable for simplicity). The index format
is incompatible with 1.8, as a result, however, and guidelines on performing the
upgrade will need to be prepared.
Given scope of the change, it may be advisable for services to prepare bootstrap files and destroy existing index databases entirely before reindexing. To discuss.
There is no previous block when validating the genesis block as part of contextual checks,
so block height cannot be used. Consensus parameters are now taken from height 0 for
the genesis check, and from block height only if the it's not the genesis block.
Updated maximum coins to match Dogecoin.
Updated protocol version to disable connections to pre-AuxPoW clients.
Disable version 2 block requirement
Update coinbase maturity to match Dogecoin
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.
Partitioning is tested over 4h and 100 blocks are insufficient
to test this for Dogecoin. We need 640 blocks in 4h for the
"abnormally high" alert test, I've found a set of 800 blocks to
test over providing sufficient margin.
Replace RPC and deterministic signatures in unit tests with Dogecoin values. While
conventionally I'd use an alternative implementation for these, as RFC 6979
compliant signature generation isn't terribly common, and there's no reason
to suspect we've modified this code, I'm going to assert that it's good enough
to test that the code doesn't provide different values.
Correct BIP32 key headers for Dogecoin, also by repacking the data.
Disabled Bitcoin PoW tests, but left code in place to simplify later merges. These are
replaced by the Dogecoin PoW tests.
