9643b2e5b5 Preserve non-flat faces in boolean modifier
This commit implements dissolving of edges which were used
to triangulate non-flat faces. This slows things down a bit
(around 5% on heave mesh with all faces triangulated).

We could improve speed of dissolve a bit here (so not a bell
to add an option for triangulation yet).

Also fixed wrong edge origindex mapping.

83617d24d5 Rework carve integration into boolean modifier
Goal of this commit is to support NGons for boolean modifier
(currently mesh is being tessellated before performing boolean
operation) and also solve the limitation of loosing edge custom
data layers after boolean operation is performed.

Main idea is to make it so boolean modifier uses Carve library
directly via it's C-API, avoiding BSP intermediate level which
was doubling amount of memory needed for the operation and which
also used quite reasonable amount of overhead time.

Perhaps memory usage and CPU usage are the same after all the
features are implemented but we've got support now:

- ORIGINDEX for all the geometry
- Interpolation of edge custom data (seams, crease)
- NGons support

Triangulation rule is changed now as well, so now non-flat
polygons are not being merged back after Carve work. This is
so because it's not so trivial to support for NGons and
having different behavior for quads and NGons is even more
creepy.

1c14ead46f Carve bundler script cleanup
- random.hpp was only removed from actual include
  directory, but not from patches/files.

- Files list generator didn't ignore config.h file
  which in fact is not needed.

18fd4bd9f4 Update Carve to newest upstream version with some assorted fixes
Perhaps some warnings could be silenced, but not in mood of writing
local patches at this moment. They're all harmless anyway.

e81f2853c8 Carve booleans library integration
==================================

Merging Carve library integration project into the trunk.

This commit switches Boolean modifier to another library which handles
mesh boolean operations in much stable and faster way, resolving old
well-known limitations of intern boolop library.

Carve is integrating as alternative interface for boolop library and
which makes it totally transparent for blender sources to switch between
old-fashioned boolop and new Carve backends.

Detailed changes in this commit:

- Integrated needed subset of Carve library sources into extern/
  Added script for re-bundling it (currently works only if repo
  was cloned by git-svn).
- Added BOP_CarveInterface for boolop library which can be used by
  Boolean modifier.
- Carve backend is enabled by default, can be disabled by WITH_BF_CARVE
  SCons option and WITH_CARVE CMake option.
- If Boost library is found in build environment it'll be used for
  unordered collections. If Boost isn't found, it'll fallback to TR1
  implementation for GCC compilers. Boost is obligatory if MSVC is used.

Tested on Linux 64bit and Windows 7 64bit.

NOTE: behavior of flat objects was changed. E.g. Plane-Sphere now gives
      plane with circle hole, not plane with semisphere. Don't think
      it's really issue because it's not actually defined behavior in
      such situations and both of ways might be useful. Since it's
      only known "regression" think it's OK to deal with it.

Special thanks to:

- Ken Hughes: author of original carve integration patch.
- Campbell Barton: help in project development, review tests.
- Tobias Sargeant: author of Carve library, help in resolving some
                   merge stoppers, bug fixing.
