Update all package using MASTER_REPOSITORY_OPENROBOTS so that they now use
MASTER_REPOSITORY_OPENROBOTS_TRAC. This is to account for the upcoming
git.openrobots.org migration.

So add a patch to use a structure encapsulating the char[].

MPC_avoidObs genom is a module encapsulating several reactive navigation
algorithm including:
    - A trajectory selection approach : a reactive navigation method
      allowing to navigate in a unknown environment by computing at each
      time step a set of candidate trajectories and selecting the best
      one
    - A trajectory following with obstacle avoidance approach : a
      reactive method trying to follow a reference trajectory while
      avoiding unforseen obstacles
