Incompatibility between _decimal and _pydecimal: Context.__hash__

Bug report

_decimal.Context.__hash__() returns an int value, while _pydecimal.Context.__hash__() is explicitly disabled:

>>> from _pydecimal import Context
>>> Context().__hash__()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'NoneType' object is not callable

I assume that _decimal just didn't bother to override __hash__ and inherits its implementation from object, but I think the implementations should match.
