* Bug: In Katabatic, in AutoContactTurn::cacheAttach() unset the
"cache invalidated" flag *only* if the h1 & v1 component are
sets. This is needed because we can attach *before* the first
cache revalidation (in the initial building stage).
* Bug: In Katabatic, in AutoSegment::getPPitch() out of bound access
of the top of the RoutingGauge, in case of a top layer segment
with a spin top flag (maybe this shouldn't happen?).
* Change: In Kite, in SegmentFsm::conflictSolveByPlaceds() take
account as conflicting other global, global, blockage *and*
now fixeds.
* Change: In Cumulus, in px2mpx.py more accurate way of transforming
the pad blockages.
* Bug: In Kite, in TrackCost, the boolean attribute "_forGlobal" was not
initialized in the constructor causing the non-deterministic behavior.
Arrrrgggghhhhhh.
* Bug: In Kite, in PyKiteEngine, forgot to perform the
"balanceGlobalDensity()" in the layer assign Python wrapper, another
cause for non-determinism.
* Change: In Kite, In KiteEngine, print the configuration at the same
point as in the python script (to get identical output).
In Katabatic & Kite, remove all hard-coded values related to track pitches.
* New: In <Session>, add more convenience function to access RoutingGauge
characteristics.
* New: In <AutoSegment>, <AutoContact>, add support for the "depth spin",
that is, if the source/target contacts are going "top" or "down".
Used to compute the perpandicular pitch. Need a small modification
of the revalidation mechanism. The observers of <AutoSegment> are
notified when the spin changes.
* New: In <AutoSegment>, the getPPitch() method allow to compute the
"perpandicular pitch". For now it is simply the greatest from the
source perpandicular pitch and the target perpandicular pitch.
Make uses of the "depth spin".
* New: In <TrackElement>, <TrackSegment>, cache the perpandicular pitch.
Updated through the notification from the observable.
