There are a few issues that cropped up in the RBTools test suite, especially when running on Python 3: - A bad merge made it so we were no longer importing parse_qsl and urlparse where they were used. - Some assertions were checking that some data were `six.text_type` when they ought to have been checking for the native string type. - A typo had `ItemResourceTests.tearDown` calling the superclass' `setUp` method instead of `tearDown`. - hgsubversion tests haven't worked for a while (the test infrastructure overrides the .hgrc but the only way to install the hgsubversion extension is via .hgrc). Unfortunately some change made it so that after the setUpClass was called, if we then skipped the test, we'd end up with a bad cwd for the rest of the test suite, resulting in a bunch of broken tests. I haven't yet fixed this, but I have improved the way that tests are skipped when hgsubversion isn't available, resulting in both faster execution and avoiding the cwd problems. - In Python 3, `re.split` behaves somewhat differently when there's a `*` character in the regex. This was resulting in SVN path splitting creating a list with every single character split instead of properly splitting only on slashes. `/+` is a more correct regex for this anyway. Testing Done: Ran unit tests on Python 2 and 3.
