Add support for SQLite backends

Configure again the build system to look for SQLite3. If the library is
found, the SQLite backend will be automatically compiled.

Enjoy *very* fast reads and writes.

MASTER PROTIP: Initialize the backend with ":memory" as the path to the
SQLite database for fully-hosted in-memory repositories. Rejoice.
