trace-cmd: Store the session tracing ID in the trace.dat file
The ID of the current tracing session is stored in the trace.dat file.
A new file option is introduced:
TRACECMD_OPTION_TRACEID
The data is stored in the file as unsigned long long integer
A new libtracecmd API is introduced, to get the ID when the trace.dat file is read:
unsigned long long tracecmd_get_traceid(struct tracecmd_input *handle);
