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

[Eric Blake]

Future patches need LGPLv2+ versions of some modules that had
recent license changes; but separating the gnulib update from
the actual use of the modules makes it easier to backport to
an older version while avoiding a submodule update (assuming,
of course, that the backport is to a system where glibc provides
adequate functionaliy without needing the gnulib module).

* .gnulib: Update to latest, for modules needed in later patches.

Pushing under the trivial gnulib rule.

* .gnulib b72ff2a...da8d59e (9):
  > regex: port to --with-included-regex --enable-gcc-warnings non-threaded
  > accept4, dup3, pipe2: port to Cygwin
  > mountlist: add support for deallocating returned list entries
  > stdalign, verify: port to FreeBSD 9.1, to C11, and to C++11
  > fnmatch: don't goto over declaration
  > pipe2: decouple from binary-io a bit
  > mgetgroups: relax license to LGPLv2+
  > xalloc-oversized: relax license to LGPLv2+
