Subject: Rewrite active/inactive client handling in client_setactive();
 client_leave() served no real purpose, likewise no reason to handle
 LeaveNotify events since an EnterNotify will process the next active client
 (and we don't have anything important to process anyway), so
 xev_handle_leavenotify() goes as well.  Allows a simplification of
 client_mtf() and client_cycle_leave() for clarity.  While here, unify a few
 client_current() checks.

No intended behaviour change.
