  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. Signed-off-by: Vicent Marti <tanoku@gmail.com>
