Update log statements
Use filesystem path conversion to string() instead of c_str().
Windows may otherwise output an address.

Steps toward multiple dbs available -- working
There will need to be some more refactoring for these changes to be
considered complete/correct, but for now it's working.

new daemon cli argument "--db-type", works for LMDB and BerkeleyDB.

A good deal of refactoring is also present in this commit, namely
Blockchain no longer instantiates BlockchainDB, but rather is passed a
pointer to an already-instantiated BlockchainDB on init().

BerkeleyDB Blockchain building, not working yet
Everything except actually *using* BlockchainBDB is wired up, but the db
itself is not yet working.  Some error about user mem not large enough.
I think I know what this error means, but I can't determine the cause.

Notes: BerkeleyDB does not allow 0-indexing in its recno type databases,
  so block numbers *in the database* will be 1-indexed.  Modifications
  to indexing have been made as needed.

BerkeleyDB BlockchainDB impl copy/paste/modify
LMDB implementation code copy/paste/modified into the Berkeley DB
implementation.  Need to test if it builds, then if it works, and so on,
but the code is all there.

Initial commit of BDB BlockchainDB implementation
Basically verbatim copy of LMDB implementation, but with the guts ripped
out and includes changed, etc.

Add support for database open with flags
Add support to:
  - BlockchainDB, BlockchainLMDB
  - blockchain_import utility to open LMDB database with one or more
    LMDB flags.

Sample use:
  $ blockchain_import --database lmdb#nosync
  $ blockchain_import --database lmdb#nosync,nometasync

BlockchainDB implementations have names now
In order to make things more general, BlockchainDB now has get_db_name()
which should return a string with the "name" of that type of db.
This "name" will be the subfolder name that holds that db type's files
within the monero folder.

Small bugfix: blockchain_converter was not correctly appending this in
the prior hard-coded-string implementation of the subfolder data
directory concept.

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.
