* ./katabatic:

- Change: In loadGlobalRouting(), more exlicit message as to why a net is
        filtered out the routing set (POWER, GROUND, CLOCK or BLOCKAGE).
    - New: ChipTool, module with utilities specific to chip routing. Containing
        a function to pre-break wires around a block.
    - New: In loadGlobalRouting/GCellConfiguration, adds supports for RoutingPad
        connected on chip's pad.
    - New: In GCellGrid/GCell, can compute the density in three modes: average,
        max of H/V and max of layer. Currently implemented in getMaxHVDensity(),
        should be unificated with getDensity(). Used for display purposes.
    - Bug: In AutoContact, when splitting a contact, add a specific check for
        "one layer span".
    - Bug: In AutoSegment::canMoveUp(), do not move up fixed segments.
