improve serialization based on feedback: make it easier to serialize a single object, or single shape, or single bvh.
Modified Bullet/Demos/ConcaveDemo to use btSerializer to serialize the btOptimizedBvh (or optionally the trimesh+bvh)
You can also serialize trimesh without BVH, use:
serializer->setSerializationFlags(BT_SERIALIZE_NO_BVH);// or BT_SERIALIZE_NO_TRIANGLEINFOMAP
Toggle between point to point and generic 6dof constraint for mouse picking in the demos
Use a 'equal vertex thresdhold' in the btVoronoiSimplexSolver of 0.0001f by default.
This can be disabled (or configured) using defaultCollisionConfiguration->getSimplexSolver()->setEqualVertexThreshold(0.f);
See http://code.google.com/p/bullet/issues/detail?id=305
move btTriangleInfoMap.h into its own header, into the BulletCollision/CollisionShapes folder
add btTriangleInfoMap pointer to btBvhTriangleMeshShape, so we don't need to use the 'userpointer' anymore
preparation for serialization of btTriangleInfoMap.

void btCollisionWorld::contactPairTest(btCollisionObject* colObjA, btCollisionObject* colObjB, ContactResultCallback& resultCallback)
cmake: improve feedback for Maya Plugin handling if the Maya base path is not detected
The user should derive its own class from ContactResultCallback and implement the following callback (similar to the gContactAddedCallback):
virtual btScalar addSingleResult(btManifoldPoint& cp, const btCollisionObject* colObj0,int partId0,int index0,const btCollisionObject* colObj1,int partId1,int index1) = 0;
See also http://code.google.com/p/bullet/issues/detail?id=27 for issue description and an example how to use this (a modified version of Bullet/Demos/ConcaveDemo)
This demo will be committed to Bullet/Demos/ConcaveDemo later.
move debugDrawWorld to btCollisionWorld.
improved CollisionInterfaceDemo, show how to perform a closest point query for objects that are not in the collision world.
removed a bit of garbage from the debug drawer
Revert btHashKeyPtr and introduce btHashPtr (to avoid breaking API/COLLADA Converter), see http://code.google.com/p/bullet/issues/detail?id=318
Disable separating distance util (it just costs CPU cycles and is disabled by default in the API anyway)
manually add some missing files to msvc projectfiles for now
fix in box-box collision detector, preventing it to fail in some rare cases
remove redundant line in btHingeConstraint, thanks to teravus
fix mouse drag camera rotation issue (modulo 360 instead of 180)
Some developers only initialize the world position, and not the orientation -> uninitialized data.
We should probably add some warning in btTransform, in debug mode. Note we don't initialize btTransform/btQuaternion/btVector3/btMatrix3x3 default constructor, for performance reasons.
Minor fixes (#ifndef SPU_COLLISION_OBJECT_WRAPPER_H block etc)
Only update 'setNumTasks' when necessary
Revert vectormath.h include (can't resolve conflicts with PS3 SDK, need additional #include path)
Also comment-out some code for __SPU__ to reduce code size
Added btContactConstraint (only used on PS3 SPU right now, better to use btPersistentManifold directly for contact constraints)
Improved readblend utility library (see also usage in http://gamekit.googlecode.com with Irrlicht)
Fix for btConvexConvexAlgorithm, potential division by zero
Thanks linzner http://code.google.com/p/bullet/issues/detail?id=260
+ 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
+ use default convex drawing instead of special cylinder drawing (caps are wrongly drawn)
+ allow camera translation using middle-mouse button in SoftDemo
+ add/removeCollisionObject virtual
Thanks Ola for this suggestion
