Jean-Paul Chaput a3963716b1 Correction in plugins to support msxlib compatible pads.
* New: In CRL Core, in helpers & alliance.conf, set and read a "PAD"
    variable to define the pad model name extension ("px" for "sxlib
    and "pxr" for vsxlib, this is provisional).
* New: In CRL Core, in plugin.conf, add parameters to define the name
    of used for power & clock supply. We may remove the extention in
    the future (to be more coherent with the previous modification).
* New: In Cumulus, in chip.Configuration.GaugeConf._rpAccess(), no
    longer place the accessing contact *at the center* of the
    RoutingPad. It works under sxlib because buffers & registers all
    have same size terminals. But this is not true under vsxlib,
    leading to misaligned contacts & wires. Now systematically place
    on the slice midlle track (maybe with one pitch above or below).
      This is still very weak as we do not check if the terminal
    reach were the contact is being put. Has to be strenthened in
    the future.
* New: In Cumulus, in chip.Configuration.ChipConf, read the new
    clock & power pad parameters.
* Change: In Isobar (and all other Python wrappers), uses PyLong instead
    of PyInt for DbU conversions. In PyHurricane argument converter,
    automatically check for both PyLong and then PyInt.
* Change: In Cumulus, in chip.PadsCorona, more accurate error message
    in case of discrepency in global net connections (i.e. no net
    of the same name in instance model and instance model owner.
* Change: In Kite, in BuildPowerRails, when looking up at the pads
    model name to find "pck_" or "pvddeck_", do not compare the
    extension part. But we still use hard-coded stem pad names,
    maybe we shouldn't.
* Bug: In Katabatic, in GCellConfiguration::_do_xG_xM1_xM3(), there
    was a loop in the search of the best N/E initial RoutingPad.
* Bug: In Kite, in KiteEngine::protectRoutingPads(), *do not* protect
    RoutingPads of fixed nets, they are already through the
    BuildPowerRails stage (and it's causing scary overlap warning
    messages).
* Bug: In Cumulus, in ClockTree.HTreeNode.addLeaf(), do not create
    deep-plug when the core is flat (not sub-modules). All the new
    nets are at core level.
* Bug: In Cumulus, in ChipPlugin.PlaceCore.doFloorplan(), ensure
    that the core is aligned on the GCell grid (i.e. the slice
    grid of the overall chip).
* Bug: In Kite, in GCellTopology::_do_xG_xM1_xM3(), infinite loop
    while looking for the bigger N-E RoutingPad. Forgot to decrement
    the index...

Jean-Paul Chaput ae4d938553 Buffer cell configuration in ClockTree. More config parameters in Chip.
* New: In ClockTree plugin, select the name of the buffer cell through
    configuration (parameter: "clockTree.buffer"), and guess the I/O
    name of this buffer automatically.
      Put configuration parameters in plugin.conf and not mauka.conf.
      Bug: strangely triggers a coredump in components collection
    when used with <vsxlib>. Some debug printing still active until
    that is solved.
* New: In Chip plugin, make the size and numbers of the block rails
    configuration parameters (in plugin.conf).

Jean-Paul Chaput 25e82fc701 Complete replacement of the Chip placement Python scripts.
Finally get rid of the demonic code from Wu Yifei...
* New: In Isobar, added encapsulation of Interval (don't know how have
    forgotten it for so long).
* Change: In Isobar, In PyLayer, new PyLink_LayerDerived() function to
    create/link the C++ object to the correct derived class and not the
    base one (PyLayer) which then prevent to use the specialized methods.
    Must replace PyLink_Layer() througout all the code.
* Change: In Isobar, in PyPoint the "setX()" & "setY()" methods where
    still capitalized.
* Change: In Isobar, in PyQuery, complete the exportation of the C++
    interface. remove the code belonging to a more "boost" way of
    building the Python interface (will do that in a far future).
* New: In CRL Core, In PyAllianceFramework, export isPad() method.
* Change: In Unicorn, in unicornInit.py, protect the loading of each
    single plugin by a "try" / "except" clause to the failing of one
    plugins do not stop the loading of the next one.
      Pass the same dictionnary argument to unicornHook() as for
    ScripMain(), this is more uniform this way.
* New: In Cumulus, complete replacement of the chip placement scripts
    from Wu Yifei (at last!). The clock-tree integration is still to
    be done.
