Closes SF patch #103123. funcobject.h: PyFunctionObject: add the func_dict slot. funcobject.c: PyFunction_New(): Initialize the func_dict slot to NULL. func_getattr(): Rename to func_getattro() and change the signature. It's more efficient to use attro methods and dig the C string out than it is to re-convert a C string to a PyString. Also, add support for getting the __dict__ (a.k.a. func_dict) attribute, and for getting an arbitrary function attribute. func_setattr(): Rename to func_setattro() and change the signature for the same reason. Also add support for setting __dict__ (a.k.a. func_dict) and any arbitrary function attribute. func_dealloc(): Be sure to DECREF the func_dict slot. func_traverse(): Be sure to traverse func_dict too. PyFunction_Type: make the necessary func_?etattro() changes. classobject.c: instancemethod_memberlist: Add __dict__ instancemethod_setattro(): New method to set arbitrary attributes on methods (really the underlying im_func). Raise TypeError when the instance is bound or when you're trying to set one of the reserved im_* attributes. instancemethod_getattr(): Renamed to instancemethod_getattro() since that's what it really is. Also, added support fo getting arbitrary attributes through the im_func. PyMethod_Type: Do the ?etattr{,o} dance.
