29b3ac7546 configure: More use of AC_ARG_VAR
AC_ARG_VAR is necessary if an environment variable influences a
configure result that is then used by other tests that are cached.
With AC_ARG_VAR, a change in the variable is detected on subsequent
configure runs and the user is then advised to remove the cache.

This adds AC_ARG_VAR calls for: MSGFMT, PERL, PYTHON, TCLSH, XML2_CONFIG

5e22171310 Make some fixes to allow building Postgres on macOS 10.14 ("Mojave").
Apple's latest rearrangements of the system-supplied headers have broken
building of PL/Perl and PL/Tcl.  The only practical way to fix PL/Tcl is to
start using the "-isysroot" compiler flag to point to SDK-supplied headers,
as Apple expects.  We must also start distinguishing where to find Perl's
headers from where to find its shared library; but that seems like good
cleanup anyway.

Extensions that formerly did something like -I$(perl_archlibexp)/CORE
should now do -I$(perl_includedir)/CORE instead.  perl_archlibexp
is still the place to look for libperl.so, though.

If for some reason you don't like the default -isysroot setting, you can
override that by setting PG_SYSROOT in configure's arguments.  I don't
currently think people would need to do so, unless maybe for cross-version
build purposes.

In addition, teach configure where to find tclConfig.sh.  Our traditional
method of searching $auto_path hasn't worked for the last couple of macOS
releases, and it now seems clear that Apple's not going to change that.
The workaround of manually specifying --with-tclconfig was annoying
already, but Mojave's made it a lot more so because the sysroot path now
has to be included as well.  Let's just wire the knowledge into configure
instead.  To avoid breaking builds against non-default Tcl installations
(e.g. MacPorts) wherein the $auto_path method probably still works,
arrange to try the additional case only after all else has failed.

Back-patch to all supported versions, since at least the buildfarm
cares about that.  The changes are set up to not do anything on macOS
releases that are old enough to not have functional sysroot trees.

b21c569cea Further improve consistency of configure's program searching.
Peter Eisentraut noted that commit 40b9f1921 had broken a configure
behavior that some people might rely on: AC_CHECK_PROGS(FOO,...) will
allow the search to be overridden by specifying a value for FOO on
configure's command line or in its environment, but AC_PATH_PROGS(FOO,...)
accepts such an override only if it's an absolute path.  We had worked
around that behavior for some, but not all, of the pre-existing uses
of AC_PATH_PROGS by just skipping the macro altogether when FOO is
already set.  Let's standardize on that workaround for all uses of
AC_PATH_PROGS, new and pre-existing, by wrapping AC_PATH_PROGS in a
new macro PGAC_PATH_PROGS.  While at it, fix a deficiency of the old
workaround code by making sure we report the setting to configure's log.

Eventually I'd like to improve PGAC_PATH_PROGS so that it converts
non-absolute override inputs to absolute form, eg "PYTHON=python3"
becomes, say, PYTHON = /usr/bin/python3.  But that will take some
nontrivial coding so it doesn't seem like a thing to do in late beta.

9da70efcbe Mop-up for setting minimum Tcl version to 8.4.
Commit e2609323e set the minimum Tcl version we support to 8.4, but
I forgot to adjust the documentation to say the same.  Some nosing
around for other consequences found that the configure script could
be simplified slightly as well.

eaba54c20c Accept tcl 8.6 in configure's probe for tclsh.
Usually the search would find plain "tclsh" without any trouble,
but some installations might only have the version-numbered flavor
of that program.

No compatibility problems have been reported with 8.6, so we might
as well back-patch this to all active branches.

509303a597 Abort if Tcl support was configured and no tcl shell was found.
This is required because the value is substituted into the pltcl_*mod
scripts.

2f2d05763d Change PL/Tcl build to use configured compiler and Makefile.shlib
system, not Tcl-provided one.

Make sure export file, if any, is cleaned.

Tcl configuration is now read directly in configure and recorded in
Makefile.global.  This eliminates some duplicate efforts and allows
for easier hand-editing of the results, if necessary.

7c1ff35410 Upgrade to Autoconf version 2.53. Replaced many custom macro
calls with new or now-built-in versions.  Make sure that all
calls to AC_DEFINE have a third argument, for possible use of
autoheader in the future.

f428d053ce Revise Tcl/Tk configuration. Make missing Tcl after --with-tcl an error,
add --without-tk option to disable Tk.  We don't need the AC_PATH_XTRA
test because tkConfig.sh already contains all the information about how to
compile and link with X.  Also make sure that libpq is up to date for
libpgtcl.  Remove executable bits from pgaccess.sh, but add it to pgaccess.
