0fbab7f changed the semantic of PyTraceBack_Print and sys.tracebacklimit. It no longer match the documentation and the behavior of the traceback module. Setting sys.tracebacklimit to 0 or less no longer suppress printing tracebacks in PyTraceBack_Print(). Setting sys.tracebacklimit to None (as at shutdown stage) no longer makes PyTraceBack_Print() using default limit, but suppress printing tracebacks and sets a TypeError without returning failure from PyTraceBack_Print().
The proposed PR restores the initial purposed semantic and fixes several other bugs in PyTraceBack_Print().
