This adds a recipe, Py3Build/InstallBuildDepends, that installs the
requirements listed in HOST_PYTHON3_PACKAGE_BUILD_DEPENDS. This allows
other (non-Python) packages to install host Python packages by calling
this recipe, without having to know the internals of python3-package.mk.
This also updates apparmor to call this recipe.

In hash-checking mode[1], pip will verify downloaded package archives
(source tarballs in our case) against known SHA256 hashes before
installing the packages.
As a consequence, this requires the use of requirements files[2] and
pinning packages to known versions.
The syntax for package Makefiles has changed slightly;
HOST_PYTHON3_PACKAGE_BUILD_DEPENDS no longer accepts requirement
specifiers like "foo>=1.0", only requirements file names (which are the
same as package names in the most common case).
This also updates affected packages, in particular:
* python-zipp: "setuptools_scm[toml]" has been split into
"setuptools-scm toml" to reuse the requirements file for
setuptools-scm (the extra depends installed by "setuptools_scm[toml]"
is toml).
* python-pycparser: This previously used ply 3.10, whereas the
requirements file will now install 3.11.

This adds PKG_BUILD_PARALLEL:=0 to packages that depend on host Python
packages (HOST_PYTHON3_PACKAGE_BUILD_DEPENDS), because installing
packages with multiple concurrent pip processes can lead to errors or
unexpected results[1].
This also:
* Move HOST_PYTHON3_PACKAGE_BUILD_DEPENDS definitions to before
python3-package.mk is included
* Update Python folder readme to include PKG_BUILD_PARALLEL:=0

This also removes a link to pypi.org; the previous sentence already
links to pypi.org, a second link in the same paragraph isn't necessary.

This adds a script that searches a Python package's source code to find
imports for separately-packaged standard library modules.
The script can be run by calling make with the configure target and
"PY3=stdlib V=s" arguments, e.g.
make package/python3-lxml/configure PY3=stdlib V=s
This also updates the readme on how to call this script, as well as more
information on Python package dependencies in general.

* Replace the Python 2 pending removal notice/schedule with a brief
message about the removal
* Replace mentions of "Python & Python 3" with just "Python" (references
to the version number are kept only in cases where it is necessary)
* Update Makefile example code to use Python 3 conventions/names

While the filespec example is technically correct, the more likely
scenario is that the files to be omitted would be inside of a package
subdirectory.
This adds an example_package directory into the example to illustrate
this case.

PKG_BUILD_DIR now takes variants into account
(openwrt/openwrt@e545fac8d968864a965edb9e50c6f90940b0a6c9), so it should
not be necessary for Python packages to set these variables anymore.

This clarifies that Python 2-only libraries will have a Python 3 version
added, instead of being replaced by a Python 3 version (before the 2020
mass removal).

After some thinking over this, documenting this behavior makes sense
versus adding some functionst to handle this.
There is some validity/use-cases where some users may want to reference
a python[3]-package.mk from some other location as well as have the
flexibility to change it (locally). One example can be when the local
`packages` is renamed to something else.
This does not fall on the responsibility of the Python maintainers, but
it can be documented.

Adding the conditionals to DEPENDS should not cause circular
dependencies any more. This adjusts the text to point out that it used
to be a problem, and if it happens again, one should open an issue.
Also, some spotted trivial errors were fixed.

This describes the proposal outlined in #8520, with a few
additions/modifications:
* Describes the handling of the Python 2 interpreter
* Allows for normal updates of Python 2 libraries that share the same
Makefile as their Python 3 version
* Mass removal event has a name
Supersedes #8788.

It was a semi-popular request a while back that I put off for a while.
Here's a quick doc.
I'll update it later as things change and I don't forget.
It also lets other people update if something is wrong.
