backport 2.9: PySymtableEntry_New(): I'm not sure what this routine is doing, but it was obviously leaking an int object when whatever the heck it's looking for was found. Repaired that. This accounts for why entering function and class definitions at an interactive prompt leaked a reference to the integer 1 each time.
