[PATCH 0/9] tests, python: prepare to expand usage of test venv

[John Snow]

GitLab CI: https://gitlab.com/jsnow/qemu/-/pipelines/548326343

This series collects some of the uncontroversial elements that serve as
pre-requisites for a later series that seeks to generate a testing venv
by default.

This series makes the following material changes:

- Install the 'qemu' package into the avocado testing venv
- Use the avocado testing venv to run vm-tests
- Use the avocado testing venv to run device-crash-test

None of these changes impact 'make check'; these are all specialty
tests that are not run by default. This series also doesn't change how
iotests are run, doesn't add any new dependencies for SRPM builds, etc.

NOTE: patch 8 isn't strictly required for this series, but including it
here "early" helps the subsequent series. Since the debian docker files
are layered, testing downstream pipelines can fail because the base
image is pulled from the main QEMU repo instead of the downstream.

In other words: I need this patch in origin/main in order to have the
venv module available for later patches that will actually need it in
our debian10 derivative images.

(in other-other-words: the 'clang-user' test *will* need it later.)

John Snow (9):
  python: update for mypy 0.950
  tests: add "TESTS_PYTHON" variable to Makefile
  tests: use python3 as the python executable name
  tests: silence pip upgrade warnings during venv creation
  tests: add quiet-venv-pip macro
  tests: install "qemu" namespace package into venv
  tests: use tests/venv to run basevm.py-based scripts
  tests: add python3-venv to debian10.docker
  tests: run 'device-crash-test' from tests/venv
