57fb21879b Expose various advanced friction options to the developer, and use a higher-quality friction model by default, to match ODE quickstep constraint solver. 
Thanks to Martijn Reuvers for bringing this up, and reproduction case.

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

a8ec916af0 Added Height Field Fluid Demo to Bullet. All code stored in the Demos/HeightFieldFluidDemo directory for now. 
Please see HfFluidDemo.cpp for examples of how to use the height field fluid along with buoyant collision shapes.

The implementation is still lacking in my ways:
1) Need to complete more collision algorithms for buoyant collision shapes
2) Support compound buoyant shapes
3) The buoyancy model isn't that great
4) Fluid volume can be lost over time

6db1b932fd Make the btDbvtBroadphase deterministic/reproducable, by sorting the btBroadphasePair using unique ID, instead of proxy address. 
The btAxisSweep3 didn't suffer from this issue, because proxies were always allocated in-order, as part of an array.

65cdd7146f Use placement new for copy constructor of arrays. Thanks to M. Reuvers for the patch. 
http://bulletphysics.com/Bullet/phpBB3/viewforum.php?f=9

Generally, however, it is best to avoid copying entire arrays, but use a 
reference.

typedef btAlignedObjectArray<btSomeClass> Array;

Array a;
Array b = a;//avoid this whenever possible

This is much better:
Array& b = a;//use a reference
const Array& b = a; //or const reference

635e1a6aa0 set broadphase handle to zero when destructing a btCollisionWorld, just in case a collision object/ rigid body is re-used. 
Thanks to Ole for reporting

Fix a bug , causing some deep penetrations to be missed. Not likely to have impacted many users, as such deep penetrations should have prevented in the first place.
Thanks a lot to Andy O'Neil for reporting and reproduction case.

a064fd2052 Use the opposite constraint axis inside the constraint solver for the second object (-normal). 
This makes it easier to port existing constraints and makes it 100% compatible with ODE quickstep constraint layout (getInfo2)

e80feca36b Big work-in-progress refactoring of the constraint solver: 
1) Add fast branchless SIMD support for constraint solver (Windows only until we get other contributions).
See resolveSingleConstraintRowGenericSIMD in Bullet/src/BulletDynamics/ConstraintSolver/btSequentialImpulseConstraintSolver.cpp
resolveSingleConstraintRowGenericSIMD can be used for all constraints, including contact, point 2 point, hinge, generic etc.

2) During this refactoring, all constraints support the obsolete 'solveConstraintObsolete' while we add 'getInfo1' and 'getInfo2' support.
This interface is almost identical interface to Open Dynamics Engine, to make it easier to port Dantzig LCP solver.

3) Some minor refactoring to reduce huge constructor overhead in math classes.
