  Log Message:
  -----------
  Fully test the C implementation of the PickleCache

Fix discrepancies between it and the Python implementation:

  - The C implementation now raises ``ValueError`` instead of
    ``AssertionError`` for certain types of bad inputs.
  - The Python implementation uses the C wording for error messages.
  - The C implementation properly implements ``IPickleCache``; methods
    unique to the Python implementation were moved to
    ``IExtendedPickleCache``.
  - The Python implementation raises ``AttributeError`` if a
    persistent class doesn't have a ``p_jar`` attribute.

Fixes #102
