* keymap.c (DENSE_TABLE_SIZE): Doc fix.

* keymap.c (DENSE_TABLE_SIZE): Doc fix.
	(keymap_table): Function removed; this function exists only to
	support an incorrect understanding of the format of keymaps.
	(access_keymap, store_in_keymap, Fcopy_keymap,
	Faccessible_keymaps): Correctly handle vectors at any point in the
	keymap; don't assume it must be at the front.
	(describe_map): Instead of calling describe_vector on the vector
	in the cadr of the keymap (if present) and then calling
	describe_alist to do the rest, just call describe_map_2.
	(describe_alist): Renamed to describe_map_2; call describe_vector
	when we encounter a vector in the list.

	* keymap.c (access_keymap, store_in_keymap): Clarify error message
	for non-ASCII characters.

	* keymap.c (access_keymap): Return the binding of Qt as the
	binding for all unbound characters.
