merge duplicate ROS-related ports in devel and misc

There are currently duplicate ports for ROS:

devel/ros-console_bridge and misc/console-bridge
devel/ros-urdfdom and misc/urdfdom
devel/ros-urdfdom_headers and misc/urdfdom-headers

This patch merges the misc ports into the devel ports. The upshot
should be that the duplication and confusion is removed but we keep
the functionality.
