In fact, it wasn't an easy choice, and it's perhaps not a definitive 
choice. The idea behind keeping  opencm3 for now is that
we want to introduce as little change possible at the beginning.

planned development schedule :

* test that pprz code built with chibios build systems runs reliably.
* let pprz run in one big chibios task and test how it behaves.
* log data to sd within another task, with api which permit to log data 
from pprz task

after we meet this first milestone : having the possibility to log data 
at high rate during flight, pprz community will have to
think if there is a need to  distribute work to more task, choosing or 
designing a lightweight orb to have
an asynchronous system for binding to event, distributing data flow, etc etc
