Until now, micropython-lib was a package that installed v1.9.3, which is
more than 6 years old. This was acceptable since micropython never made
any other official release of the library until v1.20.
Meanwhile, the libraries underwent a reorganization, and they are now
available in a directory structure that cannot be copied directly into
the target. This might explain why v1.9.3 is still present in the
current day buildroot (which comes with micropython v1.22).
As part of the changes made by the micropython project, the libraries
are now released together with the interpreter. They are cloned as a
submodule into the lib/micropython-lib directory, and are present in the
release tarball.
This commit introduces an auxiliary script to collect those libraries
and reorder them into a structure that can then be copied into
/usr/lib/micropython. The script utilizes a module from the tools
directory of the micropython repo.
The helper script is kept as simple as possible, and makes use of
existing micropython tools (used to process manifests) to discover the
list of packages available in micropython-lib. The hope is that by
relying on them, any future changes in directory structure will be
covered by the official "manifestfile.py" tool.
It is to be noted that, even though the manifestfile.py script/module is
part of the micropython package, it is actually written for CPython, and
is not expected to even work when using micropython as an interpreter.
This we do not need to introduce host-micropython to use that tool, and
microython already depends on host-python3 for other parts of the build.
With this commit, micropython-lib is installed (optionally) as part
of micropython, and thus a separate package is no longer needed. The
original config variable name was retained as it fits with the
micropython package "namespace", and thus this is backward compatible
and no legacy handling is needed.
This commit also ensures that the libraries in micropython-lib will
be updated together with newer versions of micropython in the future.
