0131754173 Add 'extractRotation' based on "A robust method to extract the rotational part of deformations" 
///See http://dl.acm.org/citation.cfm?doid=2994258.2994269
Rewrite 'diagonalize' to use 'extractRotation', should fix Issue 846

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.

40c73f327c + CMake build system fix under Windows: don't define _WINDOWS to allow Glut console demo to build properly 
+ Allow user to enable useConvexConservativeDistanceUtil . Use dynamicsWorld->getDispatchInfo().m_useConvexConservativeDistanceUtil = true;
(see Demos/Benchmarks/Benchmark4 (convex objects falling down)
+ Fix for plane drawing (just wire-frame)
+ Gimpact: use collision margin of 0.07 for demo (because BULLET_TRIANGLE_COLLISION is used)
+ replace dot,cross,distance,angle,triple in btVector3 by btDot, btCross,btDistance,btAngle,btDistance to avoid naming conflicts
+ Some fixes in GJK penetration depth normal direction (broken in a previous commit)
+ fix in calculateDiffAxisAngleQuaternion to make ConvexConservativeDistanceUtil work properly
+ allow debug drawing to debug btContinuousConvexCollision
+ add comment/warning that btTriangleMesh::findOrAddVertex is an internal method, users should use addTriangle instead

43d367d232 Fixed issue with transposeTimes. Luckily this method wasn't used in the SDK, except for some optional parts. 
Thanks Jay Lee for pointing this out!

5c80ff1f7d improved performance by adding constructors to btTransform/btMatrix3x3 to avoid conversions, compoundshape returns const references (instead of duplicate objects) 
Thanks Marten Svanfeldt, Starbreeze Studios

cf2337ed7b - Fixed a bug in btAxisSweep3 (sweep and prune) related to object removal. Only showed up when at least one btStaticPlaneShape was inserted. 
Thanks tbp for more details on reproducing case.
- Fixed issue with full 32bit integers in btAxisSweep3 (define BP_USE_FIXEDPOINT_INT_32), it used only 65536 for quantization, it should use full integer space (0xffffffff)
- Added 'getForwardVector' and getCurrentSpeedKmHour utility functions to btRaycastVehicle
- Fixed local scaling issues (btConvexTriangleMeshShape, btBvhTriangleMeshShape, removed scaling from btMatrix3x3). Thanks Volker for reporting!
- Added second filename search, so that starting BspDemo and ConvexDecompositionDemo from within Visual Studio (without setting the starting path) still works

c1a54d9edc Attempts to improve performance. Not much gain yet, but good to experiment what has effect and what hasn't. 
Added 'DO_BENCHMARK_PYRAMID' to CcdPhysicsDemo.

b73900bc60 Improved performance of convex collision shapes, cache local AABB instead of recomputation. This fixes issue with very slow performance in larger .bsp levels. 
Moved some asserts into 'btFullAssert', which is disabled by default (see btScalar.h to enable them). This is to speed-up debugging.

e9b21e21a6 Pathnames between #include files that are intended to be used within application code should not depend on the paths to the subdirectories being known to the compiler because this will not always be the case when an end-user includes your headers. 
Includes of files in the local hierarchy must not use <...> please stick with "..."

eb23bb5c0c merged most of the changes from the branch into trunk, except for COLLADA, libxml and glut glitches. 
Still need to verify to make sure no unwanted renaming is introduced.
