commit 1bbbad8b1553a7e9f2ca7b5bcb76ec47acce22f6

* Refactored ooni/runner.py again, so that it actually runs old OONITests, new
tests still work too. I tested all of them (both nettests and legacy tests)
and then diffed the results from before and after these changes. Some tests
*are* broken, e.g. dnstamper doesn't seem to find its inputs correctly, but
none of the tests are any more broken than they were before this commit --
the difference is that old tests will run.
* There was a rather nasty problem with old tests not finding their
subOptions(), which was due to Twisted's usage.Options class only being able
to handle one level of subOptions. When the old tests expected
ooni/ooniprobe.py to have the global_options and themselves to have
local_options, what was actually happening was that ooni/oonicli.py took the
first level, and then the test took the second, and thus was missing any
global_options.
* There was also a bug where, before, ooni/runner.py would do things like:
self.legacy_test.local_options = self.subOptions
when self.legacy_test is an already instantiated subclass of
ooni.plugoo.tests.OONITest. Because 'local_options' in this case is
obviously an attribute of the class, we have to do setattr(). Because of
this series of bugs, the legacy tests were missing a whole bunch of class
attributes which they required to run, read test inputs from files, and
really do anything at all.
* The function ooni.utils.legacy.start_legacy_test() now handles creating
a defer.gatherResults(defer.DeferredList), where the defer.DeferredList
is all of the calls to ooni.plugoo.tests.OONITest.startTest(args) with
all of the iterations of args.
* Added and updated a bunch of documentation.
* TODO some more documentation.
* TODO there might be more bugs. I sure as hell hope not. :(
* TODO go to bed now. I am getting grumpy.
