...
Backport r87594 r87611 and r87612 so that OrderedDict subclassing behavior
better matches dict subclassing (i.e. adding __missing__ works and
extending/overriding the update() methods doesn't break __init__()).

Improve clear() method. Keeps key/value refcnts >= 1 until final dict.clear() so that decrefs to zero won't trigger arbitrary code . Also runs a bit faster.

The rational is the change might cause imcompatiblity problems with
PyYAML. In addition, Raymond wants to kept the different versions of
collections synchronized across Python versions.
