The acceptance (aka functional, aka Avocado-based) tests are
Python files located in "tests/acceptance" that need to be run
with the Avocado libs and test runner.

Let's provide a convenient way for QEMU developers to run them,
by making use of the tests-venv with the required setup.

Also, while the Avocado test runner will take care of creating a
location to save test results to, it was understood that it's better
if the results are kept within the build tree.

A number of QEMU tests are written in Python, and may benefit
from an untainted Python venv.

By using make rules, tests that depend on specific Python libs
can set that rule as a requirement, along with rules that require
the presence or installation of specific libraries.

The tests/requirements.txt is supposed to contain the Python
requirements that should be added to the venv created by check-venv.
