* frame.c (delete_frame): New function derived from

Fdelete_frame to handle Qnoelisp value for FORCE argument.
Delete last frame iff FORCE equals Qnoelisp.  (Bug#1450)
(Fdelete_frame): Call delete_frame.  Remove line from doc-string
saying that FORCE non-nil doesn't run `delete-frame-functions'.
* frame.h: Extern delete_frame.
* window.c (window_loop):
* terminal.c (delete_terminal):
* xterm.c (x_connection_closed):
* xfns.c (Fx_hide_tip):
* w32fns.c (Fx_hide_tip): Call delete_frame instead of
Fdelete_frame.
