Reuse already existing lisp symbols for ignore_event (bug#19547).

* lisp/subr.el (while-no-input-ignore-events): Use them instead.
* src/keyboard.c (kbd_buffer_store_buffered_event):
Use help-echo for HELP_EVENT, iconify-frame for ICONIFY_EVENT,
and make-frame-visible for DEICONIFY_EVENT.
(syms_of_keyboard): Remove unneeded symbols.
