Subject: [PATCH] initial instrumentation points for the smpi component

details:
- nothing is traced yet, just coupling smpi with the tracing module
- compile simgrid with enable_trace = on
- execute it with --cfg=tracing/smpi:1
- TODO: add an option "--trace" to smpirun when this is completed
that is translated to the previously cited execution parameter
