Bug fixes for MOSIS SCMOS_DEEP support. * Change: In Hurricane, the NetRoutingProperty is moved into Hurricane from Katabatic. Needed for Knik to be able to access thoses informations. * Change: In Hurricane, in RoutingPad::setOnBestComponent(), now in case of identical area, select the component of lowest id. This should not be needed if the component ordering was fully deterministic as it should be (will investigate later). This is to ensure that the choosen component is always the same, especially between save/load of a global routing. * Bug: In Katabatic, in AutoContactHTee::updateTopology(), invalidate the segments only if the topology is valid (no NULL in the cached segments). * Bug: In Katabatic, in GCellTopology::construct(), throw an error if the topology is bad instead of trying to continue (and core dump later... ). * Bug: In Kite, in BuildPowerRails, distinguish the name of the master net in the pad (for vddi, vssi, vdde, vsse, ck, cki & cko) and the name of the net in the *chip* netlist. Must use the later to make comparison as they may differs. * Change: In Knik, in save/load solution, exclude nets that are not globally routed by Knik. That is which NetRoutingProperty is not *Automatic*. * Bug: In Cumulus, in chip.BlockPower take account of the layer width extention to sligthy shrink the connector thus avoiding a notch with standart cell in some cases. * Change: In Cumulus, in chip.ClockTree disable the use of fixed Steiner trees for the leaf clocks, as it seems overconstrained for the router. First move was to lower them in M2/M3 (instead of M3/M4) but that was not sufficent. * New: In Cumulus, RSavePlugin for recursively saving a physical hierarchy. * New: In documentation, first embryo for RDS file. Should have been in Alliance git, but I prefer to keep newest doc in Coriolis.
