ffi: Improve error reporting.
- Add a new type ffi::Context that provides an error slot.
- Functions that can return complex errors can stash the error
there, while still be convenient to use.
- For now, there is only sq_last_strerror that returns a string
representation of the error. In the future we should also return
a numeric code, and may want to expose the stack of failures.
