[Python-Dev] C-API functions for reading/writing tstate->exc_* ?

I wouldn't call the functions *Last, as this may cause confusion with
sys.last_*. I'm also unsure why the current API uses this Fetch/Restore
pair of functions where Fetch clears the variables. A Get/Set pair of
functions would be more natural, IMO (where Get returns "new"
references). This would give PyErr_GetExcInfo/PyErr_SetExcInfo.
