importlib.machinery.ModuleSpec and find_spec() were introduced in Python 3.4
under PEP 451. They replace the find_module() API of PEP 302, which was
deprecated from Python 3.4. They were removed in Python 3.12 along with the
imp module.
This change adds support for the PEP 451 APIs. Mitogen should no longer import
imp on Python versions that support ModuleSpec. Tests have been added to cover
the new APIs.
CI jobs have been added to cover Python 3.x on macOS.

* ansible: use unicode_literals everywhere since it only needs to be
compatible back to 2.6.
* compat/collections.py: delete this entirely and rip out the parts of
functools that require it.
* Introduce serializable Kwargs dict subclass that translates keys to
Unicode on instantiation.
* enable_debug_logging() must set _v/_vv globals.
* cStringIO does not exist in 3.x.
* Treat IOLogger and LogForwarder input as latin-1.
* Avoid ResourceWarnings in first stage by explicitly closing fps.
* Fix preamble_size.py syntax errors.
e.g. assert x == y -> self.assertEqual(x, y);
self.assertTrue(isinstance(x, y)) -> self.assertIsInstance(x, y)
These specific methods give more useful errors in the case of a test
failure.
