* New: In KatanaEngine::digitalInit(), when using a "VH,2RL" style,
protect all RoutingPads of each net, because unlike "2RL+" style,
the standard cell RoutingPads are not in a "below" layer only
used inside the cell, but on the V layer. So the area of the RP,
even if not fully used to connect, must be protected.
* Change: In NegociateOverlapCost(), when computing cost from a fixed
or blockage, do not set the infinite flag if it's the *same* net.
* New: In KatanaEngine::protectRoutingPads(), add a new "flags" argument
to pass on whether we want to protect the the RP candidates or just
the non-used ones.
* Change: In protectRoutingpad(), change the formula (again) to compute
the berth to give to a fixed segment... Should really try to
summarize all the case.
* Change: In TrackFixedSegment::getNet(), no longer return the blockage
net if the real net is tagged as clock.
