Martin Hoffmann b8e706b1a5 T32SIM: Integrating Tracing feature of the T32SIM. 
After each simulator break, T32Tracer retrieves the latest (16)
trace records from the T32. Memory address and value can now
be evaluated easily from the trace record.

TODO:Nevertheless we still have to traverse the trace to
find the instruction causing the access.

*
* Explanation:
* The T32_NotificationCallback_t typedef'd below has an empty parameter list,
* which we can't change anymore to a va_list because of backwards compatibility.
* This means only the native types like 'int' and 'integral type *' can be used
