Jean-Paul Chaput 59ee8358ca First working recursive place & route (Libre-SOC ALU16 benchmark).
* New: In Hurricane::Cell::isLeaf(), a leaf cell was defined as one
    without instances. Now it can be software defined with the
    "FlattenLeaf" state. If it is flagged "flatten leaf" is will be
    considered as a leaf by the trans-hierarchical walkthrough.
      This flag is also set for Cells in the Alliance CATAL.
* New: In Hurricane::Cell_LeafInstanceOccurrences::progress(), add a
    test to prune leaf cells.
* Bug: In Hurricane::getComponentOccurrences(), when calling the
    locator constructor, the "withLeafCells" argument was forgotten
    and was getting the value of "doExtraction" (wich, fortunately,
    was the same).
* Change: In Hurricane::HypreNet_LeafPlugOccurrences::progress(),
    prune the leaf cells instead of the terminal ones.
* Change: In Hurricane::HypreNet_ComponentOccurrences::progress(),
    prune the leaf cells instead of the terminal ones.
* New: In Hurricane::Cell, add a "useFlattenLeaf" mode to take into
    account or ignore the "FlattenLeaf" flag when doing trans-
    hierarchical walkthrough.
      Not sure if it shouldn't be systematic.
* New: In Etesian::toColoquinte() and other, activate the "FlattenLeaf"
    mode for all walkthough. So we can stop at already placed sub-blocks.
* Bug: In Etesian::toColoquinte(), when placed sub-block where present,
    the number of instances was under estimated, so the instance array
    was oversized and the end went unitialized. So we were getting all
    kind of strange behavior from Coloquinte...
      Now throw an exception if the number of instances differs from
    the computed size.
* Bug: In Etesian::toColoquinte(), as for the instance array, now
    correctly compute the size with the ecluded nets (supplies, clocks).
* Bug: In Etesian::resetPlacement(), event if the Cell is unplaced,
    go through the instance list to remove the potential feed cells.
      The netlist is written back after placement *with* the feed
    cells added. So, when loading again, they where cluttering the
    netlist and giving feed redefintions warning. They also generated
    erratic behaviors.
* New: In Anabatic::NetBuilderHV, added configurations for:
    * 1G_1M1_1PinM3
    * 1G_xM1_1PinM2
    * 2G_xM1_1PinM2
    * doRp_AccessNorthPin
* New: In Anabatic::NetBuilderHV, added Pin management in SingleGCell.
* Bug: In Anabatic::NetBuilderHV::_do_xG_1PinM3(), the North/South
    global routing configuration was forgotten (only East/West).
* Bug: In Katana::TrackFixedSegment, the blockage net was a static
    variable initialized at the first run. So we were getting stuck
    with the blockage net of the first cell to be routed. Of course,
    it did show only when Katana was run multiple times in the same
    process.
