make maintainer-check was obscure and rarely called in practice, and
many breakages were missed.  Fold everything that make maintainer-check
used to do into the normal build.  Specifically:

- Call duplicate_oids when genbki.pl is called.

- Check for tabs in SGML files when the documentation is built.

- Run msgfmt with the -c option during the regular build.  Add an
  additional configure check to see whether we are using the GNU
  version.  (make maintainer-check probably used to fail with non-GNU
  msgfmt.)

Keep maintainer-check as around as phony target for the time being in
case anyone is calling it.  But it won't do anything anymore.

There was a hack put into install-sh to call strip with the correct
options on Mac OS X.  But that never worked, because configure
disabled stripping on that platform altogether.  So remove that dead
code, and while we're at it, update install-sh to the latest upstream
source (from Automake).

Instead, set up the right strip options in programs.m4, so this now
actually works the way it was originally intended.

These are just cosmetic and don't seem worth back-patching far.
I put them into 9.0 just because it was trivial to do so.

update documentation accordingly.  This is required in order to have support
for a reentrant scanner.  I'm committing this bit separately in order to have
an easy reference if we later decide to make the minimum something different
(like 2.5.33).

change build system to use only Bison.  Simplify build rules, make file names
uniform.  Don't build the token table header file where it is not needed.

GNU gettext before 0.10.36 does not have that function, and is generally too
incomplete to be usable.

- Change configure.in to use Autoconf 2.61 and update generated files.
- Update build system and documentation to support now directory variables
  offered by Autoconf 2.61.
- Replace usages of PGAC_CHECK_ALIGNOF by AC_CHECK_ALIGNOF, now available
  in Autoconf 2.61.
- Drop our patched version of AC_C_INLINE, as Autoconf now has the change.

Minor rearrangements to make a few tests in a more logical order.

reliably (ie, regardless of which libraries they depend on).  Also
make sure that we don't select headers that obviously belong to the
wrong one of the two libraries.  This was discussed back around 4-Sep
but seems to have slipped through the cracks.  The header selection
could be checked more closely, perhaps, but let's see if this is good
enough.
