Module disk_db

Provides low-level access to RocksDB using some database-specific types.

This module makes sure that:

• all disk writes happen inside a RocksDB transaction ([rocksdb::WriteBatch]), and
• format-specific invariants are maintained.

Correctness

crate::constants::state_database_format_version_in_code() must be incremented each time the database format (column, serialization, etc) changes.
