* keymap.c (initial_define_lispy_key): New function, for defining

	non-ascii keys.

	* keymap.c (access_keymap): Treat bindings for Qt as default
	bindings, when new argument T_OK is non-zero.
	(get_keyelt, Fdefine_key, Flookup_key): Call access_keymap with
	T_OK false.

For example:

I haven't extended these to allow the initializing code to bind
function keys and mouse events; since they are called by many files,
I'd have to fix lots of callers, and nobody right now would be using
the new functionality, so it seems like a waste of time. But there's
no technical reason not to. -JimB */
