Jean-Paul Chaput b57c81dda8 Bug in Cell::_preDestroy().
* Bug: In Hurricane, in Cell::_preDestroy(), the classic mistake again:
    do not iterate over a collection while deleting it's elements.
    Now should be safe.
* Change: In CRL Core, set the default display style to "Alliance.Classic [black]"
    (my favorite).

Jean-Paul Chaput ed557d9027 Added support for "same layer" dogleg. Big fix for pad routing.
* Change: In Knik, in Vertex, add a "blocked" flag to signal disabled
    vertexes in the grid (must not be used by the global router).
      Modificate the Graph::getVertex() method so that when a vertex
    is geometrically queried, if is a blocked one, return a non-blocked
    neighbor. This mechanism is introduced to, at last, prevent the
    global router to go *under* the pad in case of a commplete chip.
* New: In Katabatic, in AutoSegment, a new state has been added: "reduced".
    A reduced segment is in the same layer as it's perpandiculars.
    To be reduced, a segments has to be connected on source & target to
    AutoContactTurn, both of the perpandiculars must be of the same layer
    (below or above) and it's length must not exceed one pitch in the
    perpandicular direction.
      To reduce an AutoSegment, call ::reduce() and to revert the state,
    call ::raise(). Two associated predicates are associated:
    ::canReduce() and ::mustRaise().
      Note: No two adjacent segments can be reduced at the same time.
* Bug: In Katabatic, in GCellTopology, add a new method ::doRp_AccessPad()
    to connect to the pads. Create wiring, fixed and non managed by
    Katabatic, to connect the pad connector layer to the lowest routing
    layers (depth 1 & 2). The former implementation was sometimes leading
    to gaps (sheared contact) that *must not* occurs during the building
    stage.
      Remark: This bug did put under the light the fact that the initial
    wiring must be created without gaps. Gaps are closed by making doglegs
    on contacts. But this mechanism could only work when the database if
    fully initialised (the cache is up to date). Otherwise various problems
    arise, in the canonization process for example.
* New: In Katabatic, in AutoContactTerminal::getNativeConstraintBox(),
    when anchored on a RoutingPad, now take account the potential rotation
    of the Path's transformation. Here again, for the chip's pads.
* New: In Kite, support for reduced AutoSegment. TrackSegment associateds
    to reduced AutoSegment are *not* inserted into track to become
    effectively invisibles. When a segment becomes reduced, a TrackEvent
    is generated to remove it. Conversely when it is raised a RoutingEvent
    is created/rescheduled to insert it. All this is mostly managed inside
    the Session::revalidate() method.
* New: In Kite, in KiteEngine::createGlobalGraph(), in case of a chip,
    mark all global routing vertexes (Knik) that are under a pad, as blockeds.
* Bug: In Cumulus, in PadsCorona.Side.getAxis(), inversion between X and
    Y coordinate of the chip size. Did not show until a non-square chip
    was routed (i.e. our MIPS R3000).
* Change: In Stratus1, in st_placement.py add the ClockBuffer class for
    backward compatibility with the MIPS32 bench. Have to review this
    functionnality coming from the deprecated placeAndroute.py.
      In st_instance.py, no longer creates the Plug ring of a Net.
    In my opinion it just clutter the display until the P&R is called.
    Can re-enable later as an option (in Unicorn).
* Change: In Unicorn, in cgt.py, more reliable way of loading then running
    user supplied scripts. Borrowed from alliance-checker-toolkit doChip.py	.

Jean-Paul Chaput b18219d807 Integration of the latest Coloquinte in Etesian & misc modifs.
* New: In Bootstrap, in Builder & coriolisEnv.py support for RHEL7/SL7.
    The sub-directory name is 'el7_64'.
      In qt_setup() add QtSvg to list of Qt5 & Qt4 used libraries.
* New: In Hurricane, In Cell add a placeholder for flags. First use to
    store whether the Nets have been transhierarchically flatteneds.
* New: In Hurricane, In NetRoutingState add an Unconnected flag for
    more accurate diagnosis.
* New: Hurricane, in CellViewer add an entry menu for stress tests.
    The script must be named "stressScript.py" in the cwd.
* Change: In CRL Core, in display.conf add a scaling parameter for the
    display threhold of the layer. This way we can adapt to different
    standard cells height.
* Change: In CRL Core, in ISPD05 bookshelf loader, use the pitch of the
    cell gauge instead of a hard-wired 5.0.
* Change: In Cumulus, in ClockTreePlugin, add support for Etesian placer
    and a new configuration parameter to choose between Mauka/Etesian.
* New: In Etesian, support for the latest Coloquinte.
    Add feed insertion stage.
* Bug: In Kite, In BuildPowerRails, check that _ck is not NULL before
    tring to access it's name...
* Change: In Kite, check if the Cell has it's Nets flattened before
    doing it (or not).

Jean-Paul Chaput 8bc7bd38db Add a common/ to share the trunk of symbolic technologies configurations.
In CRL Core configuration files, "display.conf", "patterns.conf" and
"technology.conf" share most of their code. So that common part is put
into "common/" and sourced from the final configuration file.
Update the documentation according the the new initialization scheme.
