Divide seat_set_trust_status into query and update.

Browse Source 
This complicates the API in one sense (more separate functions), but
in another sense, simplifies it (each function does something
simpler). When I start putting one Seat in front of another during SSH
proxying, the latter will be more important - in particular, it means
you can find out _whether_ a seat can support changing trust status
without having to actually attempt a destructive modification.
