packages can use
find_package(PythonInterp REQUIRED)
find_package(PythonLibs REQUIRED)
while we control PYTHON pointing to native py3 the libs and include
directories will then point to build host version, which can result in
unexpected combination and if we are lucky we get errors if its quite
different e.g. py2 libs/includes and py3 executable
This variable can be then used to export PYTHON_LIBRARY and
PYTHON_INCLUDE_DIR so that above find_packages can work correctly
see [1] for how it happens in cmake
LLDB uses it see [2]

I took the same approach as the recent perl upgrade: write recipe from scratch,
taking the pieces from the old recipe only when they were proven to be necessary.
The pgo, manifest and ptest features are all preserved.
New features:
- native and target recipes are now unified into one recipe
- check_build_completeness.py runs right after do_compile() and verifies that
all optional modules have been built (a notorious source of regressions)
- a new approach to sysconfig.py and distutils/sysconfig.py returning values
appropriate for native or target builds: we copy the configuration file to a
separate folder, add that folder to sys.path (through environment variable
that differs between native and target builds), and point python to the file
through another environment variable.
There were a few other patches where it was difficult to decide if the patch
is still relevant, and how to test that it works correctly; please add those
as-needed by testing the new python.

Instead of both classes using ${PYTHON_PN} (which is set by python-dir and
python3-dir), hardcode the right values so that it is possible to inherit both
pythonnative and python3native at the same time.
If both are inherited then both native Pythons are available, but the last to be
inherited will be the one to set PYTHON.

Currently, $HOME/.local is being added into sys.path for the native
Python, causing subtle host contamination. Suppress this by exporting
PYTHONNOUSERSITE = "1" as documented in PEP 370.

DEPENDS +=
Otherwise -native variants of recipes that use these classes don't get a proper python[3]-native
dependency for some reason.

STAGING_LIBDIR, PYTHON variables
We patch Python's distutils modules to access STAGING_INCDIR/LIBDIR, so when
they are not set, scripts that utilize distutils (e.g. python-config) fail.
Several recipes need to export those manually to prevent such failures,
so let's do that in the class instead.
PYTHON variable is exported because otherwise autotools' python.m4
macro will pick up its own internal default, which may not be the version
that we want.
glib recipe in particular was previously using Python 2.x during build due to python.m4
defaulting to it - now it's using Python 3.x, and so needs a small fix in
deletion of *.pyc files.

This is much cleaner than sharing python-dir.bbclass between python 2
and 3 classes, and doing confusing overrides in them.
