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().

Update Blockchain::get_db() to return reference instead of pointer
Where this method is used, a BlockchainDB object is always expected, so
a pointer is unnecessary and less safe.

blockchain_export: Add compile-time support for BlockchainDB
This allows an LMDB database to be used as the blockchain to export.

Adjust SOURCE_DB in src/blockchain_converter/blockchain_export.h
depending on needs. Defaults to DB_MEMORY.

DB_MEMORY is a sensible default for users migrating to LMDB, as it
allows the exporter to use the in-memory blockchain while the other
binaries work with LMDB, without recompiling anything.

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

Add blockchain_import utility
This imports to the blockchain database from an exported blockchain
file.

It can be used to bootstrap a new database or to add blocks to an
existing one.

Supports:
  - both the in-memory and LMDB implementations
  - optional: batching, verification, testnet

See help for usage.

Add testnet support.

Add command-line options:
  --help
  --data-dir
  --testnet-data-dir
  --testnet
  --log-level
  --batch
  --batch-size
  --block-number

See help for usage. Run at log level 1 to see profiling stats.

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.

Add compile-time support for both db implementations: in-memory and LMDB
Usage:

default is lmdb for blockchain branch:
$ make release

same as:
$ DATABASE=lmdb make release

for original in-memory implementation:
$ DATABASE=memory make release

While the dtor implementation does not actually do anything, other
paths do delete it, and the dtor might do someting later.

very, VERY primitive blockchain converter
hard-coded config folder, hard-coded BlockchainDB subclass.

Needs finessing, but should be testable this way.
