More flexible python builtin slots

Browse source 
The closure names used for builtin slots are mangled with their functype so
 that overloaded C++ method names can be used for multiple slots.
For example:
%feature("python:slot", "mp_subscript", functype="binaryfunc") SimpleArray::__getitem__;
%feature("python:slot", "sq_item", functype="ssizeargfunc") SimpleArray::__getitem__(Py_ssize_t n);
will generate closures:
  SWIGPY_SSIZEARGFUNC_CLOSURE(_wrap_SimpleArray___getitem__) /* defines _wrap_SimpleArray___getitem___ssizeargfunc_closure */
  SWIGPY_BINARYFUNC_CLOSURE(_wrap_SimpleArray___getitem__) /* defines _wrap_SimpleArray___getitem___binaryfunc_closure */
