[libvirt] [PATCH v2] maint: update to latest gnulib

[Eric Blake]

The usual portability fixes; and this includes a fix that adds
a new syntax check for double semicolons (commit 28de556 fixed
some, but gnulib found a better check).

* .gnulib: Update to latest.
* src/xenconfig/xen_common.c (xenFormatConfigCommon): Fix offender.

v1 was here: https://www.redhat.com/archives/libvir-list/2014-September/msg00230.html

Pushing under the gnulib maintenance rule; v1 was acked, and
all that differs is that gnulib now does the syntax check.
