For backwards compatibility, ldlibpath.mk kept py-path.mk included.
The projects depending on that have been fixed by now and this is no
longer needed. So, move it to the py-defs.mk where it belongs and has
narrower scope.

The following variables contain colons as path-separators:
- JW_PKG_PYTHON_PATH
- JW_PKG_EXE_PATH
- JW_PKG_LD_LIBRARY_PATH
This commit makes them use spaces instead, so they can be more
easily amended by Makefiles using them. Also define them in a more
uniform way, and use the newly introduced PREREQ_RUN variable to fill
them, which in turn can also be appended to before that.

Aside from PYTHONPATH, ldlibpath.mk runs jw-pkg.py for determining
other paths, too, which is often unneeded and can impact performance.
Split the PYTHONPATH detection into a dedicated py-path.mk, and
include it from ldlibpath.mk, so it can be used instead where needed.

As per info make, it turns out that ifndef SOME_VAR is true for
SOME_VAR defined to an empty value. This is unusable for caching, so
replace it with ifeq ($(origin SOME_VAR),undefined).

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.

Re-add everything necessary for building and packaging jw-python.
ldlibpath.mk is not strictly necessary, but might be with other
Python packages backed by compiled C-code, so leave it in.

This commit removes everything not strictly necessary for running
"make clean all" inside jw-build.
packaging jw-devtest. This cuts the repo down from 24077 to 4725
lines of code.
The idea is to
1) Further remove bloat from the remaining bits
2) Re-add what's necessary to build and package other essential repos.
The decision should be based on whether or not jw-build can also be
useful in a non-janware context.

The following BUILD_XXX variables are renamed to their respective FINAL_XXX
counterparts, as that name is more expressive:
BUILD_CFLAGS, BUILD_CPPFLAGS, BUILD_CXXFLAGS, BUILD_EXTRA_DEBUG_FLAGS,
BUILD_INCLUDE, BUILD_LDFLAGS, BUILD_LIBFLAGS, BUILD_LPPFLAGS

For performance reasons, define PATH and LD_LIBRARY_PATH with := instead of =
This is a risky commit as it might break testing due to missing libraries
