which can eliminate a subsequent call to READ_LINE::Line() for a small performance gain.

Another constructor for FILE_LINE_READER which enables more consistent file open strategies, and only call setvbuf() when the file is at position 0

their type, by using the more abstract PLUGIN::Footprint*() functions.

This is an intermediate phase only, other changes will be necessary as library table support comes in.
Encapsulate usage of library path searching, since that will go away as library table support comes in.
Add FOOTPRINT_EDIT_FRAME::{get,set}LibPath() and FOOTPRINT_EDIT_FRAME::{get,set}LibNickName() functions
to provide this encapsulation.

remove -std=c++0x compiler option since nobody is ready for it, and accordingly back into auto_ptr from unique_ptr

Fix compil issue under MinGW: for an obscure reason the option -std=c++0x creates error in wxWidget code:
some functions used in wxWidgets ( like _strdup and few other) are not defined when this option is set. 
but the equivalent option -std=gnu++0x works fine so it is used under mingw instead of  -std=c++0x.
(Under Linux/OSX  the option -std=c++0x is used)

   This required the additional compiler command line option "-std=c++0x".

2) Switch to unique_ptr from auto_ptr which is C++ deprecated.

3) Change to new English layer names per mailing list discussion, see class_board.cpp.

4) When saving to *.kicad_pcb or *.kicad_mod, identify opportunities to use wildcard
   layer sets, for pads so far.

5) Switch to two std::string hashtables in pcb_parser.cpp, away from one wxString based one
   for layer names and layer sets mapping. One hashtable holds the mask, the other the index.
   Layer sets are only in the mask table.

6) Move "LOCALE_IO toggle" into PCB_IO::Format() since it is a public API function and
   caller should find it as convenient as possible to use.  LOCALE_IO should handle
   nesting OK in the case where public Format() is called from one of the Footprint*()
   functions.

7) Drop support for "export module to new library".  Creating new libraries will have to
   be handled in concert with library table entries, and we've talked recently about
   creating a better footprint library manager, one that resides in a DLL/DSO.  So
   this kind of functionality needs to be handled in there in the near future.

8) Change name of exported PCB_IO module/footprint to *.kicad_mod and not *.emp.

switch from STREAM_OUTPUTFORMATTER to FILE_OUTPUTFORMATTER mostly throughout,and minor richio factoring

add class FILE_OUTPUTFORMATTER and use it in PCB_IO, since it is about 8-10 faster than STREAM_OUTPUTFORMATTER

fctsys.h: remove useless define.
Fix minor issues and add minor enhancements.

Fix a minor compatibility issue in .pro file for new boards, between decimils and nanometers versions of Pcbnew.

Eeschema: always stores sheet filename in unix-like notation, and fix a  bug when editing sheet file  name.
Pcbnew: add PDF format  for drill map generation.
Plotter classes: tweaking code.

* Add footprint methods to PCB_IO.
* Add FP_CACHE and FP_CACHE_ITEM for handling new footprint library design.
* Add code to save legacy libraries in new format.
* Change behavior of BOARD_ITEM::GetLayerName() to return the default layer
  name when the item does not have a BOARD as a parent.
* Minor changes to the module output formatter when writing to module library
  files (no BOARD as parent).
* Add new (and some that I forgot along the way) CMake flags to
  EDA_BASE_FRAME::CopyVersionInfoToClipboard().
* Add -Wno-narrowing to GCC flags to stop GCC 4.7 from complaining about
  a conversion from int to unsigned in the Boost polygon library.
* Add INPUT_STREAM_READER to richio.cpp to allow using any object derived
  from wxInputStream as a LINE_READER (needs to be validated).

only for Pcbnew in Decimils version. These definitions are provided, but not yet used in code.

Pcbnew, plot functions: fix bug in SVG plotter, fix a minor other bug when using PS plotter (trcak width fine adjust not working)
and plot code cleaning continued

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).

Eeschema: Plot dialogs: unify 5 dialogs (which means 5 duplicate code) to only one plot dialog (like in Pcbnew)
clean duplicate code.
Simplify HPGL dialog: plot offet removed and replace by only one option (plot origin to center of sheet or not)
This is surely enought.

Mainly to plot drill maps, but can be used to plot boards, for documentation.
The print svg still exists, but the plot SVG has more options (mirroring, holes in pads),
however  print svg allows color print, and full board printing, and plot does not.

Pcbnew: fix minor issue when loading a foorprint: if the footprint name has lower case letters, the name was asked twice

Other minor fixes.

Code cleaning, minor fixes and minor coding style fixes. wxWidgets 2.9.4 compatibility fix( deprecated function MakeModal )

Pcbnew: drag functions: serious cleanup and better code. Use now the connectivity functions to find tracks connected to pads,
and therefore  tracks are now dragged when a end point is inside a pad, not necessary on the pad position.
However, drag functions still need more cleanup.

dialog plot functions: fix compil warnings with wxWidgets 2.8
