c4548ec746 Add a helper method that creates a btCompoundShape from a btGimpactMeshShape, for more robust collision detection. 
The idea is to create tetrahedra from each surface triangle, by moving its centroid inwards along the collision normal using depth.
If the centroid hits an internal triangle, it will stop there.

The commit also includes part of the gimpact raycast performance improvement, except for the actual btCollisionWorld part
(that file was out-of-date and needs manual patching)

9eddd42347 fix win32 (non-glut) cmake build. 
add partId/index to btCollisionObjectWrapper to be able to recognize recursive shape indices (a btCompoundShape with a btGimpactShape child shape etc)

73b217fb07 Apple contribution for OSX SSE and iOS NEON optimizations unit tests, thanks to Jordan Hubbard, Ian Ollmann and Hristo Hristov. 
For OSX:
cd build
./premake_osx xcode4
for iOS:
cd build
./ios_build.sh
./ios_run.sh

Also integrated the branches/StackAllocation to make it easier to multi-thread collision detection in the near future. It avoids changing the btCollisionObject while performing collision detection.

As this is a large patch, some stuff might be temporarily broken, I'll keep an eye out on issues.

852fa3ba30 add the BT_ prefix for all #ifdef guards, to avoid conflicts with developers own header defines. 
Fixes Issue 497

//license header
#ifndef BT_RIGIDBODY_H
#define BT_RIGIDBODY_H
class btRigidBody
{
};
#endif //BT_RIGIDBODY_H

8fbe399ea4 Make .bullet serialization mode robust: 
Deal with broken DNA serialization. Bullet 2.76 release revision 2035 - 2046 was broken, and this includes the Maya Dynamica plugin.
Added some workaround to deal with the broken .bullet files, instead of crashing.

0e3b04d952 Add COLLADA physics support for GImpact (allowing dynamic moving rigid bodies using concave collision shapes) in ColladaDemo, and ColladaConverter (import and export) 
Note: ColladaConverter will export a btGImpactConvexDecompositionShape the same as a btCompoundShape, so importing an exported btGImpactConvexDecompositionShape (roundtrip) creates a btCompoundShape

d25d264e77 Improved CharacterDemo/KinematicCharacterController, dynamic objects will bounce off. 
Don't create a todo list for doxygen by default (the chaotic todo's would confuse most developers)
Improve support for small objects, by having dynamic contact breaking thresholds. Still needs small internal timestep and some GJK improvements.

8e51049359 Added btAxisSweep3::resetPool, to avoid non-determinism due to unsorted linked-list, thanks to Ole K., See http://code.google.com/p/bullet/issues/detail?id=126 
Fixed recently introduced issue: can't re-use stack as member variable (to reduce memory allocs) in btDbvt, due to recursion.
remove btGjkEpa.* from Makefile.am, Makefile and CMakeLists.txt
avoid division-by-zero in ODE boxbox contact reduction

bcd0f48c28 some doxygen updates, added some comments to classes, fix broken links, rename some prefix some internal GIMPACT collision structures using (for example use GIM_AABB instead of BT_AAABB), 
removed obsolete btGjkEpa (it was replaced by btGjkEpa2 ages ago)
