libseat/seatd: Add dispatch_pending_and_execute

This handler returns the number of dispatched or executed events, or -1
if dispatch_pending failed.

This helper is used to clean up dispatch_background, which now ensures
that all events are executed before we read or poll the connection, and
have improved error handling in the corner case where the second
dispatch_pending failed.
