  Issue 7128: Removed reference to the non-existent copyreg module.

  The reference to copyreg was a unnoticed leftover from the compatibility
  support for the grand renaming of the standard library in Python 3. The
  compatibility support was reverted in r63493, but not completely as this
  patch shows.

  Based on a patch by Amaury Forgeot d'Arc.

  Issue 5794: fix cPickle's unpickling of recursive tuples.
........

saving memory and avoiding growth in size of subsequent pickles. Proposal
and original patch by Jake McGuire.

- Add tests for the module-level load() and dump() functions.
- Add tests for cPickle's internal data structures, stressing workloads
with many gets/puts.
- Add tests for the Pickler and Unpickler classes, in particular the
memo attribute.
- test_xpickle is extended to test backwards compatibility with Python
2.4, 2.5 and 2.6 by round-tripping pickled objects through a worker
process. This is guarded with a regrtest -u xpickle resource.

pickle.py, load_build():  CAUTION:  Noted that cPickle's
load_build and pickle's load_build really don't do the same
things with the state, and didn't before this patch either.
cPickle never tries to do .update(), and has no backoff if
instance.__dict__ can't be retrieved.  There are no tests
that can tell the difference, and part of what cPickle's
load_build() did looked accidental to me, so I don't know
what the true intent is here.

exempting cPickle from running some of the proto 2 tests.

it was a godawful mess to read.
