Summary: Deprecate PyNumber_Check

Initial Comment:
I think PyNumber_Check should be deprecated.  An type
having tp_as_number does not mean it is a number.  If we
don't depreciate it, perhaps we should modify the test.
 For
example, we could check for a __int__ method.

Guido, if you decide what to do, assign the bug back to
me and I will work on a patch.

I agree that checking for tp_as_number is bogus. (Ditto for
sequence and mapping -- are these similarly naive?)

Is there any code that currently uses PyNumber_Check? 
Depending on what it is used for, I'd make a different decision.
