David van Moolenbroek 5b1db95619 IPC server: subscribe to process events on demand 
As mentioned in previous patches, services may not subscribe to
process events from specific processes only, since this results in
race conditions.  However, the IPC server can safely turn on and off
its entire subscription based on whether any System V IPC semaphores
(and, in the future, message queues) are allocated at all.  Since
the System V IPC facilities are not so commonly used, this removes
the extra round trip from PM to the IPC server and back for caught
signals and process exits in the common case.
