  Make provided/implementedBy and adapter registries respect super().

The query functions now start by looking at the next class in the MRO (interfaces directly provided by the underlying object are not found).

Adapter registries automatically pick up providedBy change to start finding the correct implementations of adapters, but to make that really useful they needed to change to unpack super() arguments and pass __self__ to the factory.

Fixes #11

Unfortunately, this makes PyPy unable to build the C extensions.

Additional crash-safety for adapter lookup.

Make the C functions get the cache only after resolving the
``required`` into a tuple, in case of side-effects like...clearing the
cache. This could lead to the ``cache`` object being deallocated
before we used it.

Drop the ``tuplefy`` function in favor of a direct call to
``PySequence_Tuple``. It's what the ``tuple`` constructor would do
anyway and saves a few steps.

Make sure that getting ``providedBy(super())`` and
``implementedBy(super())`` have no side effects.

  Log Message:
  -----------
  Remove unused str variables

The DEFINE_STRING macro prevents the linter from seeing them as unused
so I temporarily redefined it to find all such variables.
