[Libvir] gnulib: done (first two modules)

[Jim Meyering]

I've checked in all of the changes to let libvirt use
the first two modules from gnulib.

That exposed the fact that gnulib's gl_INIT macro depends
on autoconf-2.59c or newer for its definition of the m4_foreach_w
macro.  Here's a kludgey work-around patch, just committed, to
fix build failure for developers who are stuck using such old tools:
(also removed some trailing blanks)

	Accommodate developers using autoconf-2.59.
	* configure.in (m4_foreach_w): Define if not defined.

I'll propose the proper change (in gnulib) tomorrow.
