  • PyUnicode_GetSize has been deprecated since CPython 3.3, and is now gone in 3.12, so replace it with the suggestion from the official docs, PyUnicode_GET_LENGTH; this seems to fix 9 more failures with 3.12.0rc3 locally while still passing with 3.11.x

  • while I'm in the transformations neighborhood, get rid of the Python 2.x shims peppered all over the place--we're long past supporting that

from the official docs, `PyUnicode_GET_LENGTH`; this seems
to fix 9 more failures with `3.12.0rc3` locally while still
passing with `3.11.x`

rid of the Python 2.x shims peppered all over the place--we're

* force the use of a relative path for `mkdtemp` in our source code
because, from the Python `3.12` release notes:

> `tempfile.mkdtemp() now always returns an absolute path, even if the
argument provided to the dir parameter is a relative path.`

* with this patch, the full testsuite now passes on Python `3.12.0`
(which is now out) when combined with MDAnalysisgh-4301 and MDAnalysisgh-4300 (though
see my cautions about thread safety/concurrency for the latter)

* this fixes the 1 remaining failure with 3.12:
`MDAnalysisTests/analysis/test_hole2.py::TestCheckAndFixLongFilename::test_symlink_dir`
