Fix assertion on kboard->kbd_queue and other such crashes.

* src/keyboard.c (pop_kboard): Set current_kboard to the kboard of the
  selected frame when the stored kboard object has been deleted before
  pop_kboard.  
  (restore_kboard_configuration): Call pop_kboard only after setting up
  single_kboard mode.

 ** frames-on-display-list should also accept frames.
 
+** I smell something funny around pop_kboard's "deleted kboard" case.
+   Determine what are the circumstances of this case, and fix any
+   bug that comes to light.

 ** Consider the `tty-type' frame parameter and the `display-tty-type'
    function.  They serve the exact same purpose.  I think it may be
    a good idea to eliminate one of them, preferably `tty-type'.
