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

[Eric Blake]

'make syntax-check' wants a newer gnulib for 2014 copyright.

Also, a couple of fixes for bootstrap issues reported on IRC:
- on some older glibc systems, ./configure could deadlock due to
a glibc malloc bug
- on FreeBSD systems, a broken autom4te coupled with gettext
0.18.3 prevents bootstrap; we can't work around it, but can at
least inform the user why they have a problem

And as always, portability fixes in other modules, some of which
are used by libvirt.

* .gnulib: Update to latest, in part for bootstrap improvements,
and for the new year.
* bootstrap: Resync to gnulib.
* gnulib/local/m4/ssize_t.m4.diff: Regenerate.

Pushing under the build-breaker rule now that 'make syntax-check'
is impacted.

* .gnulib 831b84c...c7802e2 (33):
