Jean-Paul Chaput a6f61c1044 Update the channel routing feature to integrate with the OTC P&R.
* Update: In CRL/node600/phenitec/kite.py, update the routing gauge to
    the new format. So now we can use again SxLib-2M (channel routing
    SxLib for two metal technologies).
* Change: In CRL::BlifParser, if a master cell is not found in the
    AllianceFramework, then try in the Blif supplied libraries.
    This is used to load the zero, one and tie cells.
      Add a Blif::getCell() static function to look into the Blif
    supplied libraries.
* Change: In CRL::LefImport, sometimes there can be discrepencies between
    the LEF ROUTING layers and the Coriolis routing gauge. Now ignore
    routing layers that are *not* presents in the Coriolis gauge.

* Change: In AnabaticEngine, moved routingMode attribute from KatanaEngine,
    as some setup operations needs it.
* Change: In AutoSegment::canReduce(), allow fixed segments to be reduced
    if they are "jumpers" (turn+turn and top+top or bot+bot).
      This case arise on the edge of routing channels for fixed wires
    to connect terminals.
* Change: In AutoSegment::getTopologicalinfos(), compute differently the
    (leftBound,rightBound) interval when in channel mode.
       In over-the-cell mode, this interval is the one of the whole
    GCells under the wire. In channel mode, for fixed wires (that is,
    verticals connecteds to cells) this interval is reduced to half
    the GCell height, on the connected side of said channel.
      This allows Manipulator::_insertToTrack() to issue disantangling
    requests (push left/push right) for fixed segments that are face
    to face in the channel.
* Change: In Anabatic::Configuration CTOR, allow the cellGauge to have a
    different name from the routingGauge. Now if the cell gauge that
    should match the routing gauge is not found, fallback to the
    name set in "anabatic.cellGauge" parameter.
      Case occur when we try to match with CORE sites from LEF files.
* Change: In Etesian::Configuration CTOR, same change as in the
    Anabatic configuration.
* Change: In Anabatic::GCell::updateDensity(), never set the GoStraight
    flag in channel mode. This flag makes sense when there is at least
    4 routing layers (so we have 2 contiguous free of blockages).
* Bug: In Anabatic::Session::_getNearestGridpoint(), sometimes the nearest on
    grid point is outside the constraint box. Now force the point
    to remains inside constraints even if offgrid.

* Change: In Katana::DataNegociate::update(), perpandiculars that are
    either reduced or in non-preferred routing direction should not
    trigger a bug message.
* Change: In KatanaEngine::_check(), do not check for fixed, horizontal
    non-prefs AutoSegments in channel mode (avoid false bug display).
* Bug: In Manipulator::_forceToTrack(), slighty shrink (-1) the interval
    to free. The intersection function of intervals returns true when
    the two intervals *exactly* touches (1.vMax == 2.vMin). But in
    this specific case, they are not *overlapping* and no action
    should be taken...
* Bug: In Manipulator::_insertInTrack(), do not reject the track when
    we are overlapping a fixed vertical segment in channel mode.
    (Hmm, maybe already corrected by the previous one).
* Change: In Katana::NegociateOverlapCost(), in channel mode, do
    not put two overlaping vertical fixed segments into infinite cost.
    This happens when two cell connected verticals are face to face in
    a channel. We want them negociated the track (by shrinking their
    length) instead of excluding it right away.
* Change: In NegociateWindow::createTrackSegment(), in channel mode,
    do not attempt to create a track segment over a fixed and reduced
    AutoSegment.
      Do not attempt to put a non-preferred AutoSegment on a Track
    either.
* Bug: In RoutingEvent::revalidate(), the number of availables tracks
    was badly computed when in the pure constraint case, when there
    was only one it was reporting zero.
* Change: In TrackElements::TrackElements_Perpandicular::Locator,
    do not issue a bug when an non-pref or reduced AutoSegment do not
    have an associated TrackElement.
* Change: In TrackSegmentCost::update(), do not issue a bug when a
    perpandicular is reduded or non-pref and do not have a TrackElement.
