tracing: add trace name and id to event formats
To be able to identify the trace in the binary format output, the id of the trace event (which is dynamically assigned) must also be listed. This patch adds the name of the trace point as well as the id assigned. Signed-off-by: Steven Rostedt <srostedt@redhat.com>
