Note: we don't include the last commit from origin/recode_itti_from_scratch
because it is just astyle formatting. As of today we don't enforce
astyle and including this work would lead to future merge conflicts.
A proper process to enforce astyle has to be put in place. In the
meantime, no astyle allowed in commits if the changes are too big
and not relevant to work done.

Something like that.
