* Bug: In Anabatic::Dijsktra, correct the indentation in cdebug calls
(lots of them causing a big shift right).
* New: In Anabatic::TrackSegment, new helper structure SideStack to
manage a set of aligned GCells and their various sides sizes.
* Change: In Anabatic::TrackSegment::computeOptimal(), more accurate
computation of attractors from global segments and variable size
GCells using SideStack.
* Change: In Katana::DataSymmetric::checkPairing(), increase the tolerance
for misaligned symmetrics from 2 to 5 tracks (should be enough for our
narrow channel routing).
* New: In Katana::TrackSegment, add a first flag to enable locking of
priority. If it is set, calls to either "computePriority()" or
"forcePriority()" will have no effect. Added the uint32_t flags
paraphernalia.
* New: In ::computeNetPriority(), overall function to control the call
of TrackSegment::computeAlignedPriority(). The call is done from
NegociateWindow::run().
* New: Katana::TrackSegment::computeAlignedPriority(), order the
TrackSegments aligneds through doglegs to the one with the highest
priority is routed first and others progressively from him. Done by
forcing an ever decreasing priority on the aligneds ones.
The amount of decrease is small so the aligned segments got routed
(ordered) in close, if not contiguous, sequence. Priority is locked
for the order to remain.
* Bug: In Katana::TrackSegment::computePriority(), correct computation
of the priority when there is more than 10 free tracks
(a DbU::toLambda() call was missing, leading to very big priorities).
* Change: In katana::TrackCost CTOR, do not compute a distance to fixed
in the case of analog segments, this is backfiring.
Slight change of the compare function when delta differs. Seems
to improve a little.
