During a topdir "make all", caching variables is currently not the
first thing that happens. Instead, variables are cached as soon as a
project recurses into the make subdirectory. That was necessary,
because some makefiles were regenerated in the make subdirectory by
autoconf, potentially contributing variables that needed to be
cached.
As of now, autoconf is long gone and this is no longer true. And for
some variables, the two step process becomes involved, notably for
PYTHONPATH, which coding agents would like to look at from the topdir
very early on.
This commit moves the .project-cache.mk creation to topdir.mk, and
.projects-cache.mk creation to jw-pkg/Makefile to address that.

Every directory should have a test target, and the test target should
depend on all so that all files are generated that might be needed
for testing. This commit fixes some missing targets, and adds some
missing dependencies.

At present, the PREREQ-variable is effectively only used to detect if
prerequiste packages haven't run "make all" before make is run in a
given package. Also, it's only useful in $(TOPDIR). This commit
splits the variable up into PREREQ_BUILD and PREREQ_RUN, and makes
the variables available in every Makefile of a package by placing
them in defs.mk instead of topdir.mk.
This also fixes a problem that PREREQ was cached before being filled,
hence empty. Which effectively wasn't much of a problem, because it
was basically unused, but still.

Rename command "distro" to "pkg" together with "info", its last
remaining subcommand. "distro" is often used in the sense of "Linux
distribution", which would be too narrow for the targets jw-pkg could
theoretically support.

jw-pkg supports more than RPM-based package managers, but for
historic reasons, lots of its Makefile variables still have "RPM" in
their names. This is misleading. Replace "RPM" in variable names by
the more generic "PKG" where appropriate.

HOST_TUPLE is bastardized to contain more info that just the GNU
Triplet. Add HOST_DISTRO_INFO to do the caching job, and leave
HOST_TUPLE alone.

Meant to be overridden from the environment for debugging as in

This commit aims at improving speed by using better caching.
- Makefile, cache.mk: Split .cache.mk up
To allow caching of runtime path variables which are
project-specific, split .cache.mk up in .cache-project.mk and
.cache-projects.mk
- ldlibpath.mk: Cache ldlibpath, exepath and pythonpath
Place the output of $(call proj_query ldlibpath), $(call
proj_query, exepath) and $(call proj_query pythonpath) in
JW_PKG_LD_LIBRARY_PATH, JW_PKG_EXE_PATH, and JW_PKG_PYTHON_PATH
respectively, and cache the variables in make/.project-cache.mk.
- cache.mk: Use = instead of :=
Recursively expanded variables are nearly as fast as := variables
if the assigned value is a fixed string. And sometimes it's not,
rightly so, because variables get assigned below, as with
JW_PKG_XXX for instance.
- cache.mk: Use $(TOPDIR) as variable values
Replace absolute references to project's topdir by $(TOPDIR) with
sed. As soon as the project queries produce absolute paths, they
will be transformed into relative paths which allow the code base
to be moved to a different location and still remain functional
without a rebuild.

Implement the functionality of create-pkg-config.sh in a Python
module CmdCreatePkgConfig.py. This allows to remove
create-pkg-config.sh and jw-build-functions.sh.
Note that the translation was done pretty literally to play it safe.
More code can and should be removed by taking advantage of the fact
that jw-projects.py knows more about the project than the shell
scripts.

CC, LD and CXX are builtin, and they also override ?=, so ?= is pointless.
This solution disallows specifying a compiler from the environment. There
should be some solution with $(origin CC), but this seems too clunky for now.

It was possible for DEVEL_TARGETS to contain install_PKG_CONFIG without a

Rename CFLAGS and friends to follow the conventions of the implicit rules
defined by GNU Make:
- $(CPPFLAGS) is passed to both C++ and C compiler
- $(CXXFLAGS) is passed to C++ compiler only
- $(CFLAGS) is passed to C compiler only
- C++ compiler is in $(CXX)

This commit makes it possible to successfully run "make all" against ytools'
again, with TARGET_TUPLE set to i686-ms-w64-mingw. Lots of minor and major
tweaks here and there.
The biggest diff is a move of the architecture-related definitions into
platform.mk. The are needed pretty early on, so that seems reasonable.
Making this work again is part of the larger effort to support cross
buildchains in a more concise way, i.e. without so many if ($(TARGET),mingw))
all over the place. TARGET's relevance should dwindle, until it's finally taken
over by the TARGET_XXX variables extracted from TARGET_TUPLE or TARGET_TRIPLET.

FULL_NAME was moved back into defs.mk, which amounts to a bugfix.

This commit tries to remove the necessity to call projects.py from $(TOPDIR) to
speed up recursive builds over all projects yet again. This is a major
undertaking. There are two variables which are filled py projects.py in
$(TOPDIR): PREREQ and PREREQ_DIRS. Sadly, the latter is a path relative to
$(TOPDIR)/make, so this is kind of pointless. Unless the cache is maintained in
$(TOPDIR), a thing I tried to avoid. So this commit is only able to cache
$(PREREQ), not $(PREREQ_DIRS), which still is a hassle. Introduced defs-dirs.mk
for that, to make it accessible to make.mk, and modified all the other parts of
the machinery, too.

This commit sees several improvements to the build performance:
- Introduce cache.mk, which creates makefiles caching often used
variables, per tree and per project.
- Define more variables with := enclosed in condistions, instead of
defining them with ?=, because the RHS of ?= is expanded deferredly.
- Add more definitions for executables.
- Move some more specialized definitions out into specialized makefiles,
notably htdocs.mk and tmpl.mk
