Remove repeated coinbase tx in each exported block's data.
Add resume from last exported height to blockchain_export, making it the
default behavior when the file already exists.
Start reorganizing the utilities.
Various cleanup.
Update output, including referring to both height and block numbers as
zero-based instead of one-based. This better matches the block data,
rather than just some parts of the existing codebase.
Use smaller default batch sizes for importer when verifying, so progress
is saved more frequently.
Use small default batch size (1000) for importer on Windows, due to
current issue with big transaction sizes on LMDB.

-----------
[4-byte magic | variable-length header | block data]

4-byte file_info length

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
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
