bpo-23722: Raise a RuntimeError for absent __classcell__. (GH-6931)
A DeprecationWarning was emitted in Python 3.6-3.7.

19d246745d Issue : improve __classcell__ compatibility
Handling zero-argument super() in __init_subclass__ and
__set_name__ involved moving __class__ initialisation to
type.__new__. This requires cooperation from custom
metaclasses to ensure that the new __classcell__ entry
is passed along appropriately.

The initial implementation of that change resulted in abruptly
broken zero-argument super() support in metaclasses that didn't
adhere to the new requirements (such as Django's metaclass for
Model definitions).

The updated approach adopted here instead emits a deprecation
warning for those cases, and makes them work the same way they
did in Python 3.5.

This patch also improves the related class machinery documentation
to cover these details and to include more reader-friendly
cross-references and index entries.

944368e1cc Issue : Initialize __class__ from type.__new__()
The __class__ cell used by zero-argument super() is now initialized
from type.__new__ rather than __build_class__, so class methods
relying on that will now work correctly when called from metaclass
methods during class creation.

Patch by Martin Teichmann.

38c707e7e0 Issue : Update 147 test modules to use test discovery.
I have compared output between pre- and post-patch runs of these tests
to make sure there's nothing missing and nothing broken, on both
Windows and Linux.  The only differences I found were actually tests
that were previously *not* run.

    Backout the original 'fix' to 1721309 which had no effect.
    Different versions of Berkeley DB handle this differently.
    The comments and bug report should have the details.  Memory is allocated
    in 4.4 (and presumably earlier), but not in 4.5.  Thus
    4.5 has the free error, but not earlier versions.

    Mostly update comments, plus make the free conditional.
