archive: support interruption

Browse Source 
When lvm2 calls archive() or backup() it can be useful to allow handling
break signal so the command can be interrupted at some consistent point.

Signal is accepted during processing these calls - and can be evaluated
later during even lengthy processing loops.

So now user can interrupt lengthy lvremove().
