All: remove macros  MAX, MIN, ABS from macros.h and replace these macros by std::max, std::min and std::abs (mainly found in old code).

Code cleaning in autoroute functions.

autoroute functions: code cleaning

Some code cleaning in autoroute functions.

Minor code cleaning in autoroute files.

fix nanometer compatibility.
minor code and comments cleaning (although theses files need a lot of code cleaning)

* EDA_DRAW_PANEL completely encapsulated.
* Moved OSX m_overlay member from EDA_DRAW_PANEL to EDA_DRAW_FRAME where
  it is used.
* Doxygen comment warning fixes.

* EDA_DRAW_FRAME completely encapsulated.
* Encapsulate the the low hanging fruit in EDA_DRAW_PANEL.

* EDA_RECT and EDA_ITEM completely encapsulated.
* Removed unnecessary EDA_ITEM member m_Selected and replaced functionality
  with SELECTED flag bit.

  * Removed Pcb_Frame argument from BOARD() constructor, since it precludes
    having a BOARD being edited by more than one editor, it was a bad design.
    And this meant removing m_PcbFrame from BOARD.
  * removed BOARD::SetWindowFrame(), and BOARD::m_PcbFrame
  * Removed the global BOARD_DESIGN_SETTINGS which was in class_board.cpp
  * added BOARD_DESIGN_SETTINGS to the BOARD class, a full instance
  * a couple dialogs now only change BOARD_DESIGN_SETTINGS when OK is pressed,
    such as dialog_mask_clearance, dialog_drc, etc.
  * Removed common/pcbcommon.cpp's int g_CurrentVersionPCB = 1 and replaced it
    with build_version.h's #define BOARD_FILE_VERSION, although there may be a
    better place for this constant.
  * Made the public functions in PARAM_CFG_ARRAY be type const.
    void SaveParam(..) const and void ReadParam(..) const
  * PARAM_CFG_BASE now has virtual destructor since we have various way of
    destroying the derived class and boost::ptr_vector must be told about this.
  * Pass const PARAM_CFG_ARRAY& instead of PARAM_CFG_ARRAY so that we can use
    an automatic PARAM_CFG_ARRAY which is on the stack.\
  * PCB_EDIT_FRAME::GetProjectFileParameters() may no longer cache the array,
    since it has to access the current BOARD and the BOARD can change.
    Remember BOARD_DESIGN_SETTINGS are now in the BOARD.
  * Made the m_BoundingBox member private, this was a brutally hard task,
    and indicative of the lack of commitment to accessors and object oriented
    design on the part of KiCad developers.  We must do better.
    Added BOARD::GetBoundingBox, SetBoundingBox(), ComputeBoundingBox().
  * Added PCB_BASE_FRAME::GetBoardBoundingBox() which calls BOARD::ComputeBoundingBox()

* Replace C malloc() and free() functions with C++ new and delete
  operators or the appropriate STL container.
* Add option to end mouse capture function to skip executing the end
  mouse capture callback.
* Lots of coding policy and Doxygen comment goodness.

* More common header file compiler fixes.
* Translate French code naming and comments.
* Remove global variable ScreenPcb.
* Dead code removal.

* All header files used to create the PCB common library now compile as
  stand alone code.  This prevents the need to define them in a specific
  order to make source code compile properly.  It should also now be
  possible to relocate the source code to build the common PCB library
  to a separate folder.

* Remove sine and cosine look up tables from trigo.cpp and replace them with
  sin() and cos() math functions.
* Large include file clean up to prevent header ordering dependency build
  failures.
* Translate French code names and comments.
* Lots of coding style policy and doxygen comment fixes.

* Refactor trace search functions into the appropriate object.
* Translate French code names and comments.
* Lots of coding style policy fixes.

* Changed <wx-2.8/xml/xml.h> to "xnode.h" in pcbnew_config.cpp to fix bug
  when building against wxWidgets 2.9 and above.
* Convert broken wxXmlNode code to use XNODE.
* Overloaded XNODE constructor for creating child nodes.
* Translate French naming conventions.
* Translate French comments.
* Remove tabs from several source files.
* Coding style policy and Doxygen comment fixes.

* Change class WinEDA_MsgPanel name to EDA_MSG_PANEL per coding policy.
* Change some old set message panel code in PCBNew with updated message
  panel methods in EDA_DRAW_FRAME.
* Remove unused global function Affiche_1_Parametre.
* Minor Doxygen warning fixes.

All: fix a minor bur annoying issue: incorrect cursor shape after a block command (mainly when a tool is selected)

* Fix grid select box update bug on context menu.
* Fix via size and track width select box update bugs.
* Fix layer pair indicator button update bug.
* Fix auto track width tool bar control enable bug.
* Fix via size and track width select status bug in context menu.
* Fix layer select box and layer control widget select bug when current
  layer is removed.
* Add virtual function to notify objects derived from EDA_DRAW_FRAME that
  the units setting has changed.
* Coding policy class naming fixes.

Change board bounding box calculation to include all board items by default in pcbnew. Add a parameter to look for board edges only.

* Rename all member variables and methods that reference the cross hair
  code in draw panel object from cursor to cross hair to eliminate confusion
  between the two concepts.
* Rename cursor capture call backs in draw panel object to improve code
  readability.
* Create helper class for turning off the cross hair while drawing.
* Remove redundant block clear code.
* Remove redundant mouse capture call back reset code when end capture
  call back is called.
* Remove unused function definitions in base draw frame object.
* Lots of minor coding policy and doxygen comment fixes.

Eeschema: fix issues in drag command (mainly hotkey command and forgotten wire ends connected to components to drag).
 Rename EDA_Rect::Inside to EDA_Rect::Contains ( EDA_Rect::Inside( const EDA_Rect& aRect ) was very ambiguous )
 Fix some Doxygen warnings and erroneous comments; Add comments.

hide/show rastnest in pcbnew is currently not working, will be fixed soon

  * Moved ReturnLayerName() to static BOARD::GetDefaultLayerName() and migrated
    to a Specctra DSN compatible default layer naming scheme:
        Component becomes Front, Copper becomes Back.
  * set_color.h: Cmp becomes Front, Cu becomes Back.
  * D_PAD::DisplayInfo() changed to use actual copper layer names.
  * more layer setup dialog work, moved all programmatic wxControl instantiation
    into the wxFormbuilder environment, but this is fraught with danger:
    wxFlexGridSizer used the tallest control to establish the row heights, so
    be careful about changing control borders in the scroll panel. The vertical
    size can explode since just a couple of pixels times the number of rows
    is substantial.  Currently I am setting a 5 pixel border only left, top, and right
    but not bottom.
  * Set copper layer count is back in place as a hack until I can get the enabled
    layer bit map fully operational.
