Page readahead #203

SQLite benefits from kernel readahead whereas we don't. Let's implement readahead in userspace.

@penberg does implementing readahead in the userspace means storing more than one page in the buffer pool? Could you point me to any reference where I can read about it or code to try to understand how this should be implemented?
