32bit UID support for glibc 2.1.3

Hi,
Linux 2.3.39 contains support for 32bit UIDs and GIDs. Chris Wing has
made the patch for the kernel and also one for glibc. I'm appending a
first set of patches.
Here're some comments from Chris about the patches:
> Note that 2.3.39 does not have 32-bit UIDs in the stat structure like my
> original patches did. I'm going to get this clarified, but I'm guessing

The patches do not handle stat and stat64 yet. If stat doesn't go in,
the patch can be simplified a bit. Especially the file
sysdeps/unix/sysv/linux/32bit_uid_compat.h can go away and we can
handle __libc_missing_32bit_uids as boolean value. I'll wait for a
confirmation from the kernel side what happens and will then finalize
the patch.

For now, I haven't patched msgctl et al. We might need symbol
versioning for this and I will make a separate patch.
Also missing is support for 32bit uid in struct siginfo (already in
kernel but not in my patch). Could anybody else please look at the
patches for siginfo?
Please have a look at the patch and tell me if anything is not ok.
Ulrich, please don't apply the patch for now - I'd like first to get
some comments from the kernel side about stat.
I'll make a patch for glibc 2.2 when this patch for 2.1.3 is finished.
Btw. Mips, Alpha and Sparc64 have already 32bit UIDs - no need to
change anything for these architectures.
Thanks to Chris for the great work,
Andreas
