Jean-Paul Chaput 68e45bc5ab Groudwork for routing density driven placement. Compliance with clang 5.0.1.
This commit contains two set of features that should have been commited
separately.
  1. Compliance with clang 5.0.1, tested with the RedHat collection
     llvm-toolset-7. This allow Coriolis to be compiled under Darwin (MacOS)
     with Xcode & macports. The bootstrap install system has been modificated
     accordingly.
  2. The basic support for routing density driven placement. Related
     features are:
     * Bloat property. Each Occurrence of an Instance can be individually
       bloated. This property not attached to any tool to allow the placer and
       router to share it as wanted. Nevertheless, it is defined in Etesian.
     * BloatProfile in Katana, add individual Bloat properties to Instances
       occurrences based on the East & North overflowed edges of each GCell.
     * Support in ToolEngine for a "pass number" of a tool. This pass number
       is mainly used to make "per pass" measurements. The MeasureSet system
       is improved accordingly to support multiple values of a same measure.
     * Embryo of "P&R Conductor" to perform the place & route loop until the
       design is successfully placed. May be the first brick of a Silicon
       Compiler.

* Change: In boostrap/FindBoostrap.cmake, in setup_boost(), added tag to
    the python component for macport (ex: python27).
* Change: In boostrap/build.conf, put etesian before anabatic for
    instance occurrence BloatProperty dependency.
      Added option support for the "llvm-toolset-7" collection to build
    against clang 5.0.1.
* Bug: In Hurricane::getRecord( const pair<T,U>& ), the getSlot<> templates
    for first & second arguments must be called with <const T> and <const U>
    as the pair itself is const (and not simply <T> & <U>).
* Change: In Hurricane::getSlot() temlate, only use "string" arguments and
    not const string&, simpler for template argument deduction.
* Bug: In Hurricane::AnalogCellExtension, the StandardPrivateProperty<>
    template has a static member "_name". Clang did show that the template
    for this static number has to be put inside the namespace where the
    template *is defined* (i.e. Hurricane) instead of the namespace where
    it is instanciated (i.e. Analog).
* Bug: In Isobar, Matrix_FromListOfList(), PyInt_AsPlacementStatus() must
    be put outside the C linkage back in the Isobar C++ namespace (clang).
* Bug: In Hurricane::DBo::~DBo, and derived add a throw() specification
    (clang).
* Bug: In Hurricane::RegularLayer::getEnclosure() & setEnclosure(), change
    signature so it matches the one of the base class (clang).
* Bug: In Hurricane::CellPrinter, use double brackets for initializer list
    (clang).
* Change: In Hurricane::Breakpoint, reverse the meaning of the error level.
    Only error level *lesser or equal* than the stop level will be enabled.
* Bug: In CRL/python/helpers/__init__.loadUserSettings(), must put the
    current working directory in the sys.path as in certain configuration
    it may not be included.
* Bug: In CRL::ApDriver, DumpSegments(), no longer generate segments when
    encountering a RoutingPad on a top-level Pin Occurrence. The segment
    was generated in the wrong direction, creating DRC violations on the
    "mips_core_flat" example.
* Change: In CRL::Measures, partial re-design of the measurements management.
    Now, each kind of measure can accept multiple values put in a vector.
    The index is intented to match a tool run number.
* Change: In CRL::Histogram, add support for multiple sets of datas,
    indexeds with tool run number.
* Change: In CRL::ToolEngine, add support for multiple pass number, add
    addMeasure<> templates for the various data-types.
* Change: In CRL::gdsDriver & CRL::gdsParser(), comment out unused GDS record
    name constants.
* New: Etesian::BloatProperty, property to attach to Instance occurrences
    that contains the extra number of pitch to add to the cell width.
* Bug: In AutoSegment::CompareByDepthLength, the segment length comparison
    was wrong, it was always returning true, which broke the "strick weak
    ordering" of the comparison.
      This was producing a core-dump in GCell::updateDensity() when sorting
    a vector<>. The end() iterator was being dereferenced, leading to the
    problem.
* Bug: In Katana::DataSymmetric::checkPairing(), the test for segments
    whose axis is perpandicular to the symmetry axis was wrong
    ("!=" instead of "-").
* New: In Katana/GlobalRoute, new ::selectSegments(), selectOverloadedgcells()
    and selectBloatedInstances() to automatically select segments from
    overloaded edges, overloaded GCells and bloated cells.
* Change: In KatanaEngine, return a more detailed success state, distinguish
    between global and detailed.
      Add support for multiple routing iterations.
* New: In cumulus/python/plugins/ConductorPlugin.py, embryo of routing
    driven placement.

Jean-Paul Chaput b99a362509 Apaired segments building for symmetric routing (step 1).
* Change: In Hurricane::BaseFlags, store flags in uint64_t instead of
    unsigned int because we start to need more than 32 different flags
    in some tools.
* New: In ::getString() & ::getRecord() templates, add support for
    std::array<>.
* Change: In CRL::ToolEngine, add support for timer (time & memory
    measurements) displaced from Katabatic. This way all ToolEngine
    can use this feature. The _postCreate() method display the
    memory just after ToolEngine allocation.
* Change: In Etesian::EtesianEngine, make use of the ToolEngine
    builtin timer (remove the local one). Forgot to call the base
    class _postCreate() and _preDestroy().
* Change: In Anabatic::AnabaticEngine, make use of the ToolEngine
    builtin timer (remove the local one).
* New: In Anabatic, new AutoSegments_Connecteds() collection. This
    Collection allows a deterministic walkthough *all* the AutoSegments
    connected either to source or target of one AutoSegment.
* New: In Anabatic::AutoContactTerminal::isEndPoint() to check if an
    AutoContactTerminal is the *only one* anchored on a RoutingPad,
    thus being a true "end point" and not a kind of feed-through.
* New: In Katana::KatanaEngine, added support for symmetric nets.
    Created new class DataSymmetric to store symmetric information
    of a net (mainly the paired AutoSegments).
      Added KatanaEngine::runSymmetricRouter(), for now only build
    the DataSymmetric informations. More to come...
* Change: In Katana::GraphicKatanaEngine::_runTest(), now perform
    symmetric information building the non-symmetric routing.

Jean-Paul Chaput e2fcfcb699 Rationalization of Cell's flags. Compilation warnings hunt.
* New: In Hurricane, dedicated class BaseFlags to wrap a set of flags.
    Similar to the Mask class, only with a slightly different semantic.
    Encapsulation of <unsigned int>.
      Also provide support for the Inspector, to have a human-readable
    display of the flags.
* Change: In Hurricane, in Cell, regroup all the flags under a Flags
    sub-class of Cell. No more mixing between booleans and bit flags.
    (first use of BaseClass).
* In Hurricane, CRL Core & Knik, many small corrections to suppress
    annoying warning messages at compile time.
      Most noticeably, Bison errors in VstParserGrammar generated by
    rules and token with mismatched return value type. This was not
    problematic because the badly defined return value where not used.
    But still...

Jean-Paul Chaput 69c75b9ea9 Rewrite the Unicorn ImportCell to allow new formats to be hooked in.
* New: In Hurricane, In CellWidget, add methods to emit CellPreModificated
    and CellPostModificated Qt signals (from non-Qt aware objects).
* New: In Unicorn, In ImportCell, parsers are now dynamically hooked
    in the importer, allowing third party application (i.e. Chams) to
    add their own. See the ImportCell::addImporter() method.
* Bug: In Unicorn, in FindUNICORN.cmake, seems to be unable to detect
    the UnicornGui.h. Not a blocking problem because the include dir
    is shared with other tools correctly detected. But still...

Jean-Paul Chaput c8bcfdf174 Improved UpdateSession & exception catching. Start of RoutingGauge implem.
Miscellaneous:
* Change: In <crlcore>, in display.conf use the same display threshold
    for both METAL2 & METAL3.
      In alliance.conf, the side of VIAs in the gauge is 2l (not 3l).
      In kite.conf, separate edge densities for H/V.
* Change: In <Cell>, in flattenNets() use flag as argument, not a
    boolean. Do not create rings for clock or supply nets.
* Change: In <DeepNet>, in _createRoutingPads() do not create rings
    for clock or supply net (duplicated policy as in Cell::flattenNets()).
* Bug: In <ControllerWidget>, at last find the bad signal disconnect
    that was causing ungraceful messages.
* Change: In <knik>, in Edge display occupancy/capacity in the string
    name. Improved display progress and debugging capabilities.

Improved exception catch & breakpoint managment:
* Bug: In <PaletteWidget>, in updateExtensions() replace the calls to
    deleteLayer() by delete. This cause the widget to be immediatly
    erased instead of waiting for the event queue to be completly
    processed. This was causing the widget to be left in a incoherent
    state when stoping at a breakpoint.
* Bug: In <BreakpointWidget>, in execNoModal(), flush the main event
    loop (QApplication::flush()) *before* lauching the *local* event
    loop. This is to ensure all widgets are in their final state when
    waiting (especially <PaletteWidget>).
* Change: In <ExceptionWidget>, new method catchAllWrapper() to
    execute any std::function< void() > function/method with a "try"/
    "catch" wraparound and lauch the widget in case something is catch.
* New: In <hurricane>, support for a oberver pattern, backported from
    <katabatic> with an Obervable capable of being linked to any
    number of Obervers.
* New: In <Cell>, made it observable to detect Cell change, currently
    emit two kind of signals:
    - Cell::CellAboutToChange : *before* any change.
    - Cell::CellChanged : *after* the change has been completed.
* New: In <UpdateSession>, in Go::invalidate() add the Cell owning the
    Go to the UPDATOR_STACK (of course the cell is added only once).
    In addition, when the Cell is added, send a notification of
    Cell::CellAboutToChange to all it's observers. The slave instances
    are also invalidated.
      Conversely in UpdateSession::_preDestroy() for each invalidated
    Cell send a Cell::CellChanged notification to all observer.
      The UPDATOR_STACK has been slightly amended to accept Cell which
    are not Gos. Prior to this, the Cell where completly excluded from
    the UpdateSession mechanism, so it's instances where never actualised
    of anything referring to the Cell for that matter.
      Note: we use two different mechanisms to transmit a Cell change,
    observers and the slave instance map. I think at some point it
    should be unificated.
* Change: In <CellViewer>, make it a Cell observer to redraw when the
    cell is modificated (also update the palette).
      Uses the catchAllWrapper() to protect all critical actions.
* Change: In <GraphicTool>, no longer need of cellPreModificated and
    cellPostModificated signals. Now done through the Cell obersvers.
* Change: In <mauka>, <etesian> & <kite> now uses the catchAllWrapper
    method for protection (need to split methods in two, to be able
    to pass it as argument). No longer emit cellPreModificated and
    cellPostModificated.

Support for RoutingGauge in P&R:
* Bug: In <placeandroute.py>, the connection from the internal power
    ring to the connectors was not done correctly. Wrong contact layers
    leading to a gap.
* Change: In <BuildPowerRails>, detection of the corona signals based
    on how the "pck_px" pad is connected. No longer based on name
    matching.
* Change: In <placeandroute.py>, support for 2 routing metal only
    (3 metal in the technology).
* Change: In <katabatic> & <kite> support for a "top layer" limitation
    on the routing gauge, this allows to use only two routing metals
    (METAL2 & METAL3). Work in progress.

Jean-Paul Chaput 039e58e30a * ./crlcore/src/ccore/agds:
- Bug: In AgdsQuery::goCallBack(), take account the instance transformation.
        This problem was not showing until now because there wasn't any instances...

Jean-Paul Chaput fe7acbc389 * ./crlcore:
- Change: In ToolEngine, adds a static method "destroyAll()" that must be
        called *before* the Hurricane database destruction. This is to avoid
        a mis-oredering in destruction.
          ToolEngines are stored in a property, property are part of the DBo
        base object so are destroyed *after* the Cell derived object has been.
        Thus ToolEngine are deleted *after* the Cell components and if they
        still refers to it, we are doomed.
     - Change: In display.xml, color support for displaying references.
