Jean-Paul Chaput 02777e127e Migration towards Python3, first stage: still based on C-Macros.
* New: Python/C++ API level:
  * Write a new C++/template wrapper to get rid of boost::python
  * The int & long Python type are now merged. So a C/C++ level,
    it became "PyLong_X" (remove "PyInt_X") and at Python code
    level, it became "int" (remove "long").
* Change: VLSISAPD finally defunct.
  * Configuration is now integrated as a Hurricane component,
    makes use of the new C++/template wrapper.
  * vlsisapd is now defunct. Keep it in the source for now as
    some remaining non essential code may have to be ported in
    the future.
* Note: Python code (copy of the migration howto):
  * New print function syntax print().
  * Changed "dict.has_key(k)" for "k" in dict.
  * Changed "except Exception, e" for "except Exception as e".
  * The division "/" is now the floating point division, even if
    both operand are integers. So 3/2 now gives 1.5 and no longer 1.
    The integer division is now "//" : 1 = 3//2. So have to carefully
    review the code to update. Most of the time we want to use "//".
    We must never change to float for long that, in fact, represents
    DbU (exposed as Python int type).
  * execfile() must be replaced by exec(open("file").read()).
  * iter().__next__() becomes iter(x).__next__().
  * __getslice__() has been removed, integrated to __getitem__().
  * The formating used for str(type(o)) has changed, so In Stratus,
    have to update them ("<class 'MyClass'>" instead of "MyClass").
  * the "types" module no longer supply values for default types
    like str (types.StringType) or list (types.StringType).
    Must use "isinstance()" where they were occuring.
  * Remove the 'L' to indicate "long integer" (like "12L"), now
    all Python integer are long.
* Change in bootstrap:
  * Ported Coriolis builder (ccb) to Python3.
  * Ported Coriolis socInstaller.py to Python3.
  * Note: In PyQt4+Python3, QVariant no longer exists. Use None or
    directly convert using the python syntax: bool(x), int(x), ...
    By default, it is a string (str).
* Note: PyQt4 bindings & Python3 under SL7.
  * In order to compile user's must upgrade to my own rebuild of
    PyQt 4 & 5 bindings 4.19.21-1.el7.soc.
* Bug: In cumulus/plugins.block.htree.HTree.splitNet(), set the root
    buffer of the H-Tree to the original signal (mainly: top clock).
      Strangely, it was only done when working in full chip mode.

Jean-Paul Chaput 513bc72541 Port & integration of core2chip into alpha/block.
* New: In CRL/helpers/utils.py, create a Python "class decorator".
    Works like a decorator but without the need of implementing
    the Concrete/Abstract classes structure Design Pattern.
      Create proxies in the derived class for the base class
    attributes & methods.
* Change: In cumulus/plugins/alpha/block/configuration.py, enrich
    the BlockState object to support core2chip parameters. Make it
    even more autonomous from the Block class.
* New: In cumulus/plugins/alpha/core2chip, port of the core2chip plugin
    and integration with the alphs/block plugin. At "constant features"
    as a first. Only ported "cmos", phlib will be later.

Jean-Paul Chaput 17ecfd823b Enhanced techno rule support. Inspector support bug fix.
* Bug: In Hurricane/Commons.h, modify the getRecord<>() templates so
    that for both vector<Element> and vector<Element*>, the individual
    record created for each element are donne with pointers. That is,
    for the vector<Element> case, we take a pointer.
      As a general policy, except for the POD types, always use pointers
    or references to data in the records/inspector. Never uses values
    that can call the copy constructor.
      Suppress INSPECTOR_PV_SUPPORT() macro, keep only
    INSPECTOR_PR_SUPPORT().
      Provide value support only for getString<>() template.
      This value & copy constructor problem was causing a crash when
    trying to inspect Hurricane::AnalogCellExtension.
* New: In Hurricane::Technology, change the API of the PhysicalRule,
    now we can only create/get PhysicalRule, but setting the value of
    the rule itself must be done on the rule.
      Enhance PhysicalRule to provide for stepped rules, non isotropic
    and ratio rules.
      Merge TwoLayersPhysicalrule in PhysicalRule, much simpler to
    suppress the management of derived classes. That means that we
    loose a little memory as some fields are mutually exclusive.
    Not a problem considering that there will not be so many of thoses
    objects.
* New: In CRL/helpers.analogtechno.py, enhanced DTR support for rules
    like:
      ('minSpacing'  , 'metal1', ((0.4,20.0), (0.8,1000.0)), Length, 'REF.1')
      ('minEnclosure', 'metal1', 'cut1', (0.2,0.3)         , Length, 'REF.2')
      ('minDensity'  , 'metal1', 0.30                      , Unit  , 'REF.3')
      The DTR parser has been updated, but not the oroshi.dtr Rule
    cache for analog components. Given a rule name, the value used
    will be the horizontal one of the first step.
* Change: In hurricane/doc/hurricane, re-generate the documentation
    with updated support for Technology & PhysicalRule.

Jean-Paul Chaput a50b6ce317 More PEP8 compliant Python code. Start rewrite Python/C++ wrappers.
* Change: In CRL/helpers, cumulus/plugins, oroshi & karakaze,
    Move towards more Python PEP8 compliance:
      * All indentations sets to 4 spaces (in progress).
      * In plugins, remove messages about software collections
        and RHEL (too many case could wrongly lead to that).
	Instead systematically uses "helpers.io.catch()".
      * Put in lowercases all modules names. Note that C++ exported
        modules *keep* their Capitalized names (to preserve the
	identity with the C++ namespace).
      * When making import, use full path.
      * Rename the run function from "ScriptMain()" to "scriptMain()".
* Cleanup: In CRL/etc, remove obsoleted configuration files,
    the one ending in ".conf". Keep those who have not been ported
    to the new style yet.
* New: In Hurricane/src/configuration, first trial at replacing the
    C preprocessor macros by C++ templates. Applied first to configuration
    from VLSISAPD.
      This is unfinished business, just a limited demonstrator for now.
      It is installed as a separate Python library "Cfg2" which do not
    interact with the rest of Coriiolis.
      The end goal is to fully remove boost and merge VLSISAPD useful
    components directly inside Hurricane.
