I would like to deprecate PyUnicode_AsUnicode(), see the issue #22271 for the rationale (hint: memory footprint).

To deprecate PyUnicode_AsUnicode(), we should stop using it internally.

The attached patch is a work-in-progress patch, untested on Windows (only tested on Linux). It gives an idea of how many files should be modified.

TODO:

* Modify posixmodule.c: I don't understand how the Argument Clinic generates the call to PyUnicode_AsUnicode() when the parameter type is declared as "unicode". What is the "unicode" type? Where is the code generating the call to PyUnicode_AsUnicode()?

* Modify a few other files.
