[10/13] constify deprecate_cmd

  This constifies deprecate_cmd and the "replacement" field in struct
cmd_list_element.

2014-07-22  Tom Tromey  <tromey@redhat.com>

	* cli/cli-decode.c (deprecate_cmd): Make "replacement" const.
	* cli/cli-decode.h (struct cmd_list_element) <replacement>: Now
	const.
	* command.h (deprecate_cmd): Update.
	* maint.c (maintenance_do_deprecate): Add casts.
