Remove the need to have run-at-time.el.

Remove the need to have run-at-time.el.

XEmacs now has `timer-funcs.el' which correctly implements
`run-at-time' and many other GNU timer functions using itimers.  This
patch also cleans up the rest of Gnus for timer/itimer compatibility.
XEmacs users will no longer need the fsf-compat package to build or to
run Gnus.

	* run-at-time.el: Removed.  It is no longer needed as
	timer-funcs.el in the xemacs-base package has a working version of
	`run-at-time'.

	* gnus-xmas.el: Require timer-funcs instead of run-at-time.

	* password.el: Require timer-funcs instead of run-at-time in
	XEmacs.
	Remove `password-run-at-time' macro.
	(password-cache-add): Use `run-at-time' instead of
	`password-run-at-time'.

	* nnheaderxm.el: Require timer-funcs instead of run-at-time.
	Remove `nnheader-cancel-function-timers' alias,
	`cancel-function-timers' exists in XEmacs in timer-funcs.

	* mail-source.el: Require timer-funcs instead of itimer in XEmacs
	for `run-with-idle-timer'.

	* gnus-demon.el: Require timer-funcs instead of itimer in XEmacs
	for `run-at-time'.

	* mm-url.el: Require timer-funcs at compile time when in XEmacs
	for `with-timeout'.

	* dgnushack.el: Autoload the correct `setenv' for SXEmacs which is
	the same as for XEmacs 21.4.
	No need to ignore `run-with-idle-timer', this function exists in
	XEmacs now in timer-funcs.el in the xemacs-base package.
	(dgnushack-compile): No need to delete
	run-at-time.el from the list of files to compile because it
	doesn't exist anymore.

	* gpg.el: Add timer/itimer compatibility.
