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

[Eric Blake]

While we aren't impacted by most of upstream's changes this
month, at least the regex improvement looks useful.

* gnulib: Synchronize to upstream.
---

Pushing under trivial rule before we go into freeze.

* .gnulib 72fb907...ce457d6 (16):
  > gitlog-to-changelog: include a dummy git-log-fix file
  > autoupdate
  > update from texinfo
  > gitlog-to-changelog: also include the file, git-log-fix
  > autoupdate
  > regex: port to OS X 10.8.5 en_US.UTF-8 locale
  > maint: fix ChangeLog to match commit record
  > stdint, read-file: fix missing SIZE_MAX on Android (tiny change)
  > parse-datetime: fix crash or infloop in TZ="" parsing
  > * NEWS: Recent changes are not that important.
  > savedir: new symbol for fast-read version
  > unistd: port readlink to Mac OS X 10.3.9
  > * NEWS: Document recent change to diffseq.
  > diffseq: remove TOO_EXPENSIVE heuristic
  > savedir: simplify by using stpcpy
  > spawn: fix link error on uclibc
