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

[Eric Blake]

Among other things, gnulib now allows overriding of sed during
'make syntax-check'.

* .gnulib: Update to latest, for maint.mk improvements.

Pushing under the maintainer rule, before we freeze.  I still need
to revive Roman's work on using $(SED) and/or portable sed constructs
in our cfg.mk, but that can occur after freeze if necessary, while
the hard part of the gnulib submodule should be done before freeze.

* .gnulib d5fec6c...3f51bf4 (9):
  > maintainer-makefiles: use $(SED) for syntax check
  > update from texinfo
  > savedir: add sorting arg to savedir, streamsavedir; remove fdsavedir
  > autoupdate
  > update from texinfo
  > update from texinfo
  > file-type: add support for doors and other less-common file types
  > update from texinfo
  > autoupdate
