Check if LMDB needs resize every 1000 blocks
(this was 10 for testing purposes)

LMDB should now dynamically resize the mapsize
Some filesystems (*cough* NTFS *cough*) aren't good with sparse files,
so this makes LMDB dynamically resize its mapsize as needed.  Note: the
check interval is currently every 10 blocks (for testing) and will
probably need to change to 1000 or something.  Default mapsize set to
1GiB.

Blockchain conversion tools using batching will probably segfault, I'll
fix that in the next commit.

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().

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.
