Option -A disables that (the default, does nothing at the moment)

(cherry picked from commit 840a26c515db6b45fda5bce35422db3a7c2f09d5)
The release was deliberately set to 8.1 rather than 9,
as we don't want to beat Fedora 40 to it.
This adds a new `%_python_memoize` macro that caches the values of
various python macros in a lua table based on the current value of
`%__python` / `%__python3`. The Python macros are adjusted to use this
macro for memoization instead of the current approach. This way, the
macros will return values that apply to the _current_ `%__python3` value
when packagers create multi-python specfiles that toggle the value of
`%python3_pkgversion`.

%py3_install_egg is nonfunctional; setuptools removed the easy_install
entrypoint years ago.
%py3_build_egg is technically functional but has been superseded by
newer macros. Calling setup.py directly is deprecated, and
building/installing eggs to begin with is deprecated.
The macros are not used in any Fedora packages and are broken.
It's time to remove them.
Macros like %{python3_sitelib} were evaluated at every instance in the spec
(each time, Python was started, sysconfig was imported...).
When there were many instances (40+), it might have taken more than a minute to parse the spec file.
This way, the macros are defined via %global on first usage.
Every repetitive usage reuses the actual value.
When reviewing https://src.fedoraproject.org/rpms/pyproject-rpm-macros/pull-request/291
we have discovered that there is no macronized way to get this part of some paths
and that packagers need to hardcode it as cpython-%{python3_version_nodots}.
This way, we have a standardized macro packagers (and other macros) can use.
I.e. when %python3_pkgversion is 3.12, %__python3 is /usr/bin/python3.12
We assume that when packagers pacakge for Python 3.X, they want to change both
%python3_pkgversion and %__python3 value.
Hence instead of copy-pasting this:
%global python3_pkgversion 3.X
%global __python3 /usr/bin/python3.X
They just need to do:
%global python3_pkgversion 3.X
Packagers who want to change the value of %__python3 without touching
%python3_pkgversion can still do it:
%global __python3 /usr/bin/pypy3

%%py{3}_check_import now respects the custom setting of %%py{3}_shebang_flags
and invokes Python with the respective values.
If %%py{3}_shebang_flags is undefined or set to no value,
there no flags are passed to Python on invoke.

-f: optionally read a file with module names to test
-t: bool flag - if set, filter only top-level modules
-e: optionally exclude module names matching the given glob (Unix
shell-style wildcards)
Importing all modules may cause bogus failures in some cases,
eg. when the imported code assumes there is an existing graphical window.
Such behaviour may be by design, hence for automatic processing it's
more convinient to - in some cases - check only for top-level modules
or filter out the troublemakers.
With $PATH and $PYTHONPATH set to the %buildroot,
the macro tries to import the given Python 3 module(s).
Useful as a smoke test in %check when ruining tests is not feasible.
Accepts spaces or commas as separators.
Package python-six:

Distutils which were used to define the macros are deprecated in Python3.10:
https://www.python.org/dev/peps/pep-0632/.
Sysconfig isn't and it works across our Pythons, making it better choice for the task.
This allows e.g.:
%global extras cli,ghostwriter,pytz,dateutil,lark,numpy,pandas,pytest,redis,zoneinfo,django
%{pyproject_extras_subpkg -n python3-hypothesis %{extras}}
...
%pyproject_buildrequires -x %{extras}
(Note that %pyproject_extras_subpkg is a tiny wrapper around %python_extras_subpkg.)
This only works for package and extra names less than 79 characters long.
I don't expect many actual packages to exceed this limit.
78 characters should be enough for everybody.
Why 78? 79 is the line-lenght limit from rpmlint.
And we need to put punctuation in there.
Versioned pathfixX.Y.py is available in main as well as in
alternative Pythons so this change enables to build
an alternative Python stack without a dependency on the main
python3-devel.
By default, %{py3_dist foo} generates python3dist(foo).
This change makes it respect %python3_pkgversion so when
it is redefined as X.Y, %{py3_dist foo} generates pythonX.Y(foo).
See https://fedoraproject.org/wiki/Changes/PythonMacroError
While doing it, make %python macros more consistent with %python3 macros,
mostly wrt whitespace but also to use python -m pip over plain pip etc.
One significant change is the removal of sleeps from python macros,
this could affect packages that use python macros to build for Python 2
while also using python3 macros to build for Python 3.
In reality, I consider that unlikely. The sleep in python2 macros stays.
The --strip-file-prefix option was already removed from %pyX_install_wheel
but we forgot to remove it from %py_install_wheel.
Previous implementation allowed for only one argument to be passed to
the %pycached macro, which made it impossible to combine it with other macros.
Current implementation allows to pass other macros as arguments to
%pycached.
Example:
%pycached %exclude /path/to/foo.py
For macro expansion limitations, the opposite order is not possible.
That is to be documented in the guidelines:

Added some tests.
