The top-level makefile removes tmp_install in its "clean" target, but the
distclean and maintainer-clean targets overlooked that (and they don't
simply invoke clean, because that would result in an extra tree traversal).

While at it, let's just make sure that removing GNUmakefile itself is the
very last step of the recipe.

The "check" target no longer needs to depend on "all", because it now
runs "install" directly, which in turn depends on "all".  Doing both
will cause problems with parallel make, because two builds will run next
to each other.

Also remove the redirection of the temp-install output into a log file.
This was appropriate when this was done from within pg_regress, but now
it's just a regular make run, and especially with the above changes this
will now take the place of running the "all" target before the test
suites.

problem report by Jeff Janes, patch in part by Michael Paquier

Before, make check-world would create a new temporary installation for
each test suite, which is slow and wasteful.  Instead, we now create one
test installation that is used by all test suites that are part of a
make run.

The management of the temporary installation is removed from pg_regress
and handled in the makefiles.  This allows for better control, and
unifies the code with that of test suites not run through pg_regress.

Providing this information as plain text was doubtless worth the trouble
ten years ago, but it seems likely that hardly anyone reads it in this
format anymore.  And the effort required to maintain these files (in the
form of extra-complex markup rules in the relevant parts of the SGML
documentation) is significant.  So, let's stop doing that and rely solely
on the other documentation formats.

Per discussion, the plain-text INSTALL instructions might still be worth
their keep, so we continue to generate that file.

Rather than remove HISTORY and src/test/regress/README from distribution
tarballs entirely, replace them with simple stub files that tell the reader
where to find the relevant documentation.  This is mainly to avoid possibly
breaking packaging recipes that expect these files to exist.

Back-patch to all supported branches, because simplifying the markup
requirements for release notes won't help much unless we do it in all
branches.

These do not run any specific schedule of tests, but only those
specified as part of the invocation, e.g.:

    make check-tests TESTS="json jsonb"

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.

This is for convenience, now that adding recursive targets is much
easier than it used to be when the NLS stuff was initially added.

This fixes failures under parallel make when contrib modules use a
generated backend header file (such as errcodes.h).

Added a new option --extra-install to pg_regress to arrange installing
the respective contrib directory into the temporary installation.
This is currently not yet supported for Windows MSVC builds.

Updated the .gitignore files for contrib modules to ignore the
leftovers of a temp-install check run.

Changed the exit status of "make check" in a pgxs build (which still
does nothing) to 0 from 1.

Added "make check" in contrib to top-level "make check-world".

This can do various source code checks that are not appropriate for
either the build or the regression tests.  Currently: duplicate_oids,
SGML syntax and tabs check, NLS syntax check.

Also add make check-world target, and refactor pg_regress invocation
code in makefiles a bit.

Replace for loops in makefiles with proper dependencies.  Parallel
make can now span across directories.  Also, make -k and make -q work
properly.

GNU make 3.80 or newer is now required.

A proposed patch will require GNU make 3.80 or newer.  We will let this patch
run for a while to see how much damage that would do to the buildfarm.

It is no longer installed by default, but included in "make world"/"make
install-world".  Documentation updated accordingly.

Also, fix vpathsearch function to work when calling make install-docs
without previous make docs.

Add new make targets "world", "install-world" and "installcheck-world" to build, install and check just about everything.
In addition to everything built installed and tested by all, install and installcheck targets, these build HTML Docs,
build and test contrib, and test PLs and ECPG.

Documentation files in HTML and man formats are now prepared for
distribution using the distprep make target, like everything else.  They
are placed in doc/src/sgml/html and manX and installed from there by
make install, if present.  The business with the tarballs in the tarball
is gone.

Test coverage support now covers the entire source tree, including
contrib, instead of just src/backend.  In a related but independent
development, the commands make coverage and make coverage-html can be run
in any directory.

This turned out to be much easier than feared.  Besides a few ad hoc fixes
to pass the make target down the tree, change all affected makefiles to
list their directories in the SUBDIRS variable, changed from variants like
DIRS and WANTED_DIRS.  MSVC build fix was attempted as well.
