[Bug libc/2210] New: [PATCH] Move sys/io.h to sysdeps/{i386,x86_64}/

["rmh at aybabtu dot com" <sourceware-bugzilla at sourceware dot org>]

Former discussion in libc-alpha (see
http://sources.redhat.com/ml/libc-alpha/2002-09/msg00153.html) suggests that it
is not a problem if sys/io.h declares iopl() when the system doesn't have it. 
Besides, iopl() can be implemented in userland when kernel offers an interface
with similar functionality (for kFreeBSD, we implemented it as a wrapper to
/dev/io).

If we count i386-pc-kfreebsd-gnu and x86_64-pc-kfreebsd-gnu, that'll be at least
5 platforms using a copy of the same sys/io.h file (only with cosmetical
differences).  I think it makes sense to move to sysdeps/i386 and sysdeps/x86_64
so that the file can be shared between them.

Please consider the attached patch.
