Dpow (#2)

* Add main dpow header file with support for regtest+testnet dpow simulation * KMD notaries are now stored in a dedicated file This makes it very easy for coins with DPoW to update a single file when new notaries are elected once per year. * Add core dpow consensus-changing code + getinfo data * This is BTC 0.12.1 internals, so rename our header file * Fix some compile issues * Fix more compiler errors+warnings * Fix some compile errors * Fix more compile issues * More fixes * More compile errors * Add kmd rpc header * Make this beast of burden finally compile Thank you baby Buddha. * This is messy but has synced up to 232195 blocks already and continues * Basic dpowconfs support * Get rid of warning * Add passing dpow tests ./qa/pull-tester/rpc-tests.py dpowconfs ./qa/pull-tester/rpc-tests.py dpow * This was for debugging and most likely needs to go back this way
