Update blockchain utilities with portable bootstrap file format
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.

Fix incompatibility with blockchain exporter when source is LMDB
Instantiate BlockchainDB in blockchain exporter to reflect recent
updates.

This applies when blockchain_export.h defines SOURCE_DB as DB_LMDB.

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.
