* hurd.h, hurd/hurd/fd.h, hurd/hurd/port.h, hurd/hurd/signal.h,

	hurd/hurd/threadvar.h, hurd/hurd/userlink.h: Instead of
	_EXTERN_INLINE, use a macro specific to each file,
	_HURD_FD_H_EXTERN_INLINE and the like.
	* hurd/Makefile (inline-headers): New variable.
	(routines): Remove hurdinline.  Add $(inlines).
	(inlines): New variable.
	($(inlines:%=$(objpfx)%.c)): New static pattern rule to generate them.
	(generated): Append those here.
