	* kern/rescue.c (pupa_rescue_cmd_rmmod): Call pupa_dl_unload, if
	possible.

	* kern/dl.c (pupa_dl_ref): Refer dependending modules
	recursively.
	(pupa_dl_unref): Unrefer depending modules recursively.
	Don't call pupa_dl_unload implicitly, because PUPA can crash if
	a module is unloaded before one depending on that module is
	unloaded.
	(pupa_dl_unload): Unload depending modules explicitly,
	if possible.
