- as client objects are now allocated along with network manager clients
and will be accounted for by the network manager, there's no longer a
need to call exit_check(). its functions are now replaced by the
nmhandle reset and put callbacks.
- there is no need to keep a 'clients' list in ns_clientmgr()
- (however, TODO, the client manager should now be reference counted)
- added some logging to show when clients are allocated, reset, or freed
- ns_client_next() has no remaining function except to log the reason
for a failure. its name has therefore been changed to ns_client_drop().
