just have it return the slot number or -E... - the caller checks
the sign anyway

new waiting-for-slot logics:
* make request for slot wait for bufmap to be set up if it
comes before it's installed *OR* while it's running down
* make closing control device wait for all slots to be freed
* waiting itself rewritten to (open-coded) analogues of wait_event_...
primitives - we would need wait_event_locked() and, pardon an obscenely
long name, wait_event_interruptible_exclusive_timeout_locked().
* we never wait for more than slot_timeout_secs in total and,
if during the wait the daemon goes away, we only allow
ORANGEFS_BUFMAP_WAIT_TIMEOUT_SECS for it to come back.
* (cosmetical) bitmap is used instead of an array of zeroes and ones
* old (and only reached if we are about to corrupt memory) waiting
for daemon restart in service_operation() removed.

it's always equal to __orangefs_bufmap and the latter can't change
until we are done

This only changes the names of things, so there is no functional change.

All callers were outside of the file these functions were declared in,
so nothing was ever inlined anyway.
Further this happens before I/O and any speedup by not having to do a
call will be dwarfed by the time it takes to talk to the server.
