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

[Eric Blake]

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.
* bootstrap: Resync to gnulib.

Hmm, in reading this gnulib changelog, I'm not sure I want to
push right away: the line about md5 being tweaked to use openssl
makes me wonder if this update is dragging in a new library
dependency; I'll have to do a bit more investigation.  But
here's the patch, if anyone else also wants to investigate.

* .gnulib 831b84c...fdfe96f (18):
  > bootstrap: warn about BSD toolchain snafu
  > open-tests: port to glibc with _FORTIFY_SOURCE and -O1
  > include_next: minimize code duplication
  > getcwd: fix compile error in configure check
  > regex: suppress core dumps from detection code
  > md5, sha1, sha256, sha512: support mandating use of openssl
  > test-xvasprintf: disable some -Wformat-security diagnostics
  > regex: avoid glibc deadlock during configure
  > md5, sha1, sha256, sha512: use openssl routines if available
  > base64: fix recent compilation regression on some compilers
  > autoupdate
  > autoupdate
  > ignore-value: revert previous code change
  > selinux-h: improve stub types and add more stub functions
  > ignore-value: prefer GCC version back through 2.0
  > pty: Activate the signature wrapper of forkpty.
  > maint: fix gendocs.sh permissions
  > autoupdate
