Moved BlockchainDB into its own src/ subfolder

Ostensibly janitorial work, but should be more relevant later down the
line.  Things that depend on core cryptonote things (i.e.
    cryptonote_core) don't necessarily depend on BlockchainDB and thus
have no need to have BlockchainDB baked in with them.
