* Fix some Windows tests
* Remove any test (or part of a test) that references `find_module()`.
* Use assertIsNone() / assertIsNotNone() consistently.
* Update Doc/reference/import.rst

Previously, we were blocking the frozen imports and forcing the source
version to be used, but we did not fix up sys.meta_path or
sys.path_hooks, causing the frozen importers to leak into the source
version of the test.
attributes to None.
The long-term goal is for people to be able to rely on these
attributes existing and checking for None to see if they have been
set. Since import itself sets these attributes when a loader does not
the only instances when the attributes are None are from someone
overloading __import__() and not using a loader or someone creating a
module from scratch.
This patch also unifies module initialization. Before you could have
different attributes with default values depending on how the module
object was created. Now the only way to not get the same default set
of attributes is to circumvent initialization by calling
ModuleType.__new__() directly.
__loader__ is not set on a module. This brings the exception in line
with when __loader__ is None (which is equivalent to not having the
attribute defined).
__loader__ for this test to succeed without a major changes. It also
doesn't test the original issue of modules imported by Py_Initialize()
having __loader__ set (the rest of the test covers that).
scratch. This means they do not set __loader__ by default. This is
acceptable under importlib/PEP 302 definitions, so relax the test that
was trying to apply this universally.
state of the import system. Also make importlib.invalidate_caches()
work with sys.meta_path instead of sys.path_importer_cache to
completely separate the path-based import system from the overall
import system.
