[PATCH] lib-sql: sql-api - Implement async calls for drivers that can't

Changes the behaviour of asynchronous functions to be truly asynchronous
even if the underlying driver isn't capable of doing this. Implemented
by adding immediate timeouts to call the callbacks after returning from the
synchronous function and ending up back to ioloop.
