[Libvir] [PATCH] Update from gnulib.



I ran ./bootstrap against a just-updated gnulib directory, so these
changes now sync into libvirt all of the changes from gnulib since
the last time:

	Update from gnulib.

FYI, nearly all of these changes are also in the latest coreutils
beta/test release, so if there are problems, I should hear about
it soon.

If you'd like to see justification for a particular change,
you'll probably find it in a combination of these:

  gnulib's ChangeLog file
  a unit test change or addition,
  a message on the bug-gnulib mailing list.
