CGo-free port of SQLite/SQLite3.

Is your feature request related to a problem? Please describe.
Maintain two kind of executable files with the only goal to support sqlite is not worth it. The reason to do this is that sqlite3 heavily relies on gcc. We need a alternative.

Describe the solution you'd like
Recently a CGo-free port came out and it's starting to do numbers out there. We should replace the current sqlite driver and only maintain one CGO disabled binary.
