'make syntax-check' complained about something that was already
fixed upstream in doc/standards.texi, so I ran 'make update', and
omitted lib/Autom4te as that still has some issues to be sorted out.

The files in lib/Autom4te/ are intentionally not synced at this point,
since automake commit v1.11-2114-g2d671e1 "perl refactor: use modern
semantics of 'open'":
<http://lists.gnu.org/archive/html/automake-patches/2012-03/msg00111.html>
would require wider adaptation of our scripts to the new XFile API, and
also exposes some latent bugs in autoconf where we use raw 'open' instead
of XFile::open. We'll take care of that in a later patches (maybe).

* cfg.mk (gnulib-update): Add them to the list.
* maint.mk: Update from gnulib.
* build-aux/gitlog-to-changelog: Likewise.
* build-aux/useless-if-before-free: New file, from gnulib.
* doc/gnu-oids.texi: Update.
Following the practice set by various other GNU projects, we start
to automatically generate the ChangeLog file from the git commit
messages. This will avoid duplication (as the ChangeLog entries
were always inserted both in the git commit message and in the
version-controlled ChangeLog file), and potential problems with
spurious merge conflicts (which, although greatly mitigated by
Bruno Haible's `git-merge-changelog' helper program, have never
been completely solved).
* ChangeLog: Moved ...
* ChangeLog.3: ... to this.
* build-aux/gitlog-to-changelog: New script, synced from gnulib.
* cfg.mk (gnulib-update): Also sync gitlog-to-changelog.
* Makefile.am (gen-ChangeLog): New .PHONY rule, generate the
ChangeLog for distribution.
(dist-hook): Depend on it.
($(srcdir)/ChangeLog): New dummy rule, to pacify automake "gnu"
strictness. Creates a dummy ChangeLog, that will be overridden
by the proper one at distribution time.
(gen_start_date): New variable, the date starting from which the
git log entries are to be copied in the generated ChangeLog.
(EXTRA_DIST): Add ChangeLog.3 and gitlog-to-changelog.
* configure.ac (AC_CONFIG_SRCDIR): Use 'lib/autoconf/autoconf.m4'
instead of 'ChangeLog' as the sentinel file.
* .gitignore: Add ChangeLog.
