This was added in 2014, we can safely depend on it being available
now. Existing tests will ensure it doesn't regress

Add (after comma) or remove (before opening round bracket, and around
'=' in arguments) whitespaces according to the PEP 8 specification.
This is just code reformatting, with no behaviour changes; no content
changed beside whitespaces, so "git diff -w" gives an empty diff.
Instead of running all the tests manually, the unittest module has a
'discovery' mode to run tests by importing them from a directory: this
requires the tests to have different filenames, since they need to be
imported as modules now (hence an empty __init__.py is added), and the
current naming does not match the convention.
Using unittest as loader/runner brings another change: tests skipped as
whole cannot be done anymore with exit(77), since they are not run but
imported: thus introduce an helper module with decorators applied to the
test classes to skip them according to the current checks. This also
gets us nicer recordings in the unittest log.
Due to the relative imports (needed for the helper code), it is no more
possible to execute tests anymore by invoking them manually; although
it is possible to run single tests, still using unittest's runner:
$ cd python
python$ ../run python -m unittest discover -v t test010Load.py
This does not change anything in what the tests do/check.
