Add support for the v3 file format.
This file format improves savepoints.
Savepoints in the v3 format have constant, and small, overhead. Creating
and restoring them is also much faster. The v3 file format also supports
savepoints on large databases (v2 has a limit around 32TB). This release
creates v2 databases by default. Use Builder::create_with_file_format_v3()
and Database::upgrade(), respectively, to enable and migrate to v3.
The upcoming 3.0 release will only support the v3 file format.
