Jean-Paul Chaput 49a37addae Add the ability to specify the H-track position of a H-Tree.
Formerly, the H-Track could be shifted *relative* to the position of
the center of the RoutingPad. Which may become fragile in case of a
change in the standard cell library. So we create a new feature allowing
to specify the H-track as an offset *from the bottom of the slice*.
Two offset can be specified:
  * spares.htreeOffsetDriver : for the main H part, connected to the
      driver.
  * spares.htreeOffsetSink : for the small parts connecting to every
      fours sinks of the tree.
  This to avoid those two to overlap. The sink of the "N" stage with
the driver of the "N+1" stage (so input & ouput of the same buffer).

Jean-Paul Chaput 1557d613ae Comprehensive reorganisation of the Python part of Coriolis.
* Move all Python stuff under a common Python namespace "coriolis".
* Instead of having a series subtrees for each tool, integrate
  everything in one common tree. So now, all components can be
  located either with an absolute path from "coriolis" or, inside
  cross-reference themselves through relatives imports.
* As a consequence, we only need to add ".../site-packages/coriolis/"
  to the PYTHONPATH, and not a whole bunch of subdirectories.
  And nothing, if installed in-system.
* The tree of free technologies configuration files is also moved
  below "coriolis/technos" instead of "/etc".
* Supressed "cumulus" level for the plugins.
* All python modules are rewritten using relative imports except
  for the configuration files that uses absolute import as they
  can be cloned outside of the tree to serve as templates.

* Change: In boostrap/FindPythonSitePackages, include "/coriolis" in
    Python_CORIOLISARCH and Python_CORIOLISLIB.
      Provide a Python_SITELIB *without* "/coriolis" appended.
* Change: In cumulus/plugins/__init__.loadPlugins(), must prefix modules
    read in the plugins directory by "coriolis.plugins.". No longer need
    to add their path to sys.path.
* Change: In crlcore/python/technos/nodeX/*/devices.py, the scripts of
    the layouts generators must be prefixed by "coriolis.oroshi.".
* Change: In CRL::System CTOR, no longer add the pathes of the various
    plugins to sys.path. Only "site-packages/coriolis/".
* New: In Utilities::Path::toPyModePath(), new method to convert a
    filesystem path into a python module path.
      Examples:
        "coriolis/plugins/block"    --> "coriolis.plugins.block".
        "coriolis/plugins/rsave.py" --> "coriolis.plugins.rsave".
* Change: In katanaEngine::_runKatanaEngine(), rename the hook script
    initHook.py. No longer need to modify sys.path.
* Change: In BoraEngine::_runBoraEngine(), rename the hook script
    initHook.py. No longer need to modify sys.path.
* Change: In UnicornGui::_runUnicornInit(), rename the hook script
    initHook.py. No longer need to modify sys.path.
* Change: In cumulus.plugins.chip.constants, put the constants
    outside __init__.py to avoid a loop at initialization.
