Move CCM ouput to update step.

Browse source 
Move CCM to update all data at update step, as final step can only
output at most a block length, so outputting all data at this step
significantly breaks the tests. Had to add unpleasant workaround for the
validate stage, but this is the only way I can do things without
breaking CCM Alt implementations.
