[PATCH] Undeprecate GNU/Hurd

[Mark Kettenis <kettenis@chello.nl>]

I no longer have a system running the Hurd :-(.  So these changes are
untested.  They might not even compile.  However the changes are
fairly straightforward and obvious.  And I did double-check for
spelling mistakes.  Hopefully someone else can check this.  I'll see
if I can prod someone.

I've committed this anyway.

Mark

	* i386gnu-nat.c: Update copyright year.
	(gnu_store_registers): Don't use deprecated_registers and
	deprecated_registers_valid.  Use regcache_valid_p and
	regcache_raw_supply instead.
