In Anabatic/Katana, add support for VH gauges (real technos). 

* Change: In Anabatic::AutoContactTerminal::getNativeConstraintBox(),
    when the anchor is a RoutingPad (which must be always the case),
    perform the true computation of it's position based on the
    segment occurrence. It is a important change, previously the
    area was in fact the "center line" of the connector while now
    it is really an area (mandatory for "half-offgrid" terminals of
    real technologies).
      The change is not complete yet, the area should be shrinked
    by the half size of a VIA, because the area applies to the center
    coordinate of the VIA (to be done quickly).
* Bug: In Anabatic::AutoContactTurn::updateTopology(), when a dogleg
    is created (restore connexity after a layer change) the layer of
    the VIA, based on the segments it connects to must be re-computed
    *after* the dogleg has been made.
* Change: In all files of Anabatic, when comparing two layers, no longer
    use the Layer pointer itself, but the layer mask. This allow a
    transparent management of both real and symbolic layers (which
    do share the same mask). Real metal layers (not VIAs) will be
    BasicLayer and symbolic metal layers will be RegularLayer.
* New: Anabatic::Configuration::selectRpComponent(), select the best
    RoutingPad component for metal1 terminals. Look for the metal1
    component with the biggest accessibility on-grid.
      RoutingPad using other metals are left untoucheds.
* New: New function Anabatic::Vertex::getNeighbor(Edge*) to get the
    neighbor Vertex through an Edge*. This method allows to write
    clearer code as we no longer need to access the neighbor through
    the underlying GCell.
      Also add proxies for GCell methods in Vertex.
* Bug: In Anabatic::Dijkstra::_toSources(), in the ripup stage, when
    a component with multiples vertexes is reached *and* two of it's
    vertexes are reached *at the same time* (one from which we backtrack
    and one still in the queue) extraneous edges may be created by
    _materialize(). Case occurs on snx/c35b4, "abc_5360_n903_1".
      To solve this, Dijkstra::_toSource() is modificated, the "from"
    edges of the newly reacheds vertexes are reset to NULL, *except*
    for the one we will be backtracking from. That is, the one given
    in the source argument.
* Change: In Anabatic::NetBuilder class, put the various Hooks and
    RoutingPad sorting functions as class ones.
* Bug: In AutoSegment::setLayer(), raise the SegInvalidatedFayer flag.
    This unset flag was causing AutoContactTurn::updateTopology()
    to not work as expected and making gaps, this was the cause of
    the last remaining warnings about layer connexity.
