Fix several bugs in handling of exceptions with trace function enabled.
If the callback raised an exception but did not set curexc_traceback,
the trace function was called with PyTrace_RETURN. That is, the trace
function was called with an exception set. The main loop detected the
exception when the trace function returned; it complained and disabled
tracing.
Fix the logic error so that PyTrace_RETURN only occurs if the callback
returned normally.
The trace function must be called for exceptions, too. So we had
to add new functionality to call with PyTrace_EXCEPTION. (Leads to a
rather ugly ifdef / else block that contains only a '}'.)
Reverse the logic and name of NOFIX_TRACE to FIX_TRACE.
Joint work with Fred.
