* Added a new method flag, METH_COEXIST.
* Used the flag to optimize set.__contains__(), dict.__contains__(),
dict.__getitem__(), and list.__getitem__().

+- Created a new method flag, METH_COEXIST, which causes a method to be loaded
+ even if already defined by a slot wrapper. This allows a __contains__
+ method, for example, to co-exist with a defined sq_contains slot. This
+ is helpful because the PyCFunction can take advantage of optimized calls
+ whenever METH_O or METH_NOARGS flags are defined.
+
- Added a new function, PyDict_Contains(d, k) which is like
PySequence_Contains() but is specific to dictionaries and executes
about 10% faster.
