- Use `define-coding-system-alias' instead of `copy-coding-system'.

- Register `coding-priority', `input-method' and `features' keys
  into language-info-alist.

	* mule/japanese.el: Add coding: local variable, to avoid
	bootstrapping problem if you need to recompile all the Lisp
	files using interpreted code.
