Improvements in routing quality for ARMv2a, reached 100% success. 

Now reliably work for 20 successive runs (doRun.sh) with pseudo-random
variations.
* Change: In AnabaticEngine::computeNetConstraints(), fully recompute
    the "distance to RoutingPads" for all AutoSegments.
      Previously we tried to do it incrementally, but as it's computed
    as a minimum, it stayed stuck at the lowest value, event after a
    net's change of topology that could made it increase (a new dogleg
    did appear between the segment and the RoutingPad).
