module compat for py3.8+ controller ()
* module compat for py3.8+ controller

* replaced internal usages of selinux bindings with internal ctypes binding (allows basic selinux operations from any Python interpreter), plus tests

* added new respawn_module API to allow modules to import Python packages that are only available under a well-known interpreter, plus tests

* added respawn logic to modules that need Python libs from a specific system interpreter (apt, apt_repository, dnf, yum)

minimize internal HAVE_SELINUX usage

spurious junk

pep8

* pylint fixes

* add RHEL8 Python 3.8 testing

* more pylint

* import sanity

* unit tests

* changelog update

* fix a bunch of stuff

* tweak changelog

* fix setup_rpm_repo on EL8

* misc sanity/test fixes

* misc feedback tweaks

* fix import fallback in test module

* fix selinux MU test

* fix dnf tests to avoid python-dependent test packages

* add trailing LFs to aliases

* fix yum tests to avoid test package with Python deps

* hack create_repo for EL6 to create noarch package
