Suggested spec if someone wants to implement this:
1) factor out the discard code from release_pv_segment so it can be shared
and used on existing segments too;
2) Add vgtrim (+man page) which takes VG-style arguments, uses
process_each_pv_in_vg which uses process_each_segment_in_pv which checks if
segment is free and if so calls the code from (1) to issue a discard on it.
