Got a license from Intel for vtune. The first performance analysis showed an unexpected bottleneck:
...
apparently the UnionFind / island management had unexpected overhead. Added path compression to the UnionFind::find operation, and iterative over the actual islands, rather then over all number of objects.

updated CMakeLists.txt to include LibXML and LibColladaDom, and use better naming for libs. This should allow autogeneration of visual studio projectfiles, and Apple XCode projectfiles for COLLADA_DOM demo.

This provides a better maintainable alternative to jam/msvcgen

more compounds work, the basics work. now some stackless tree-tree traversal is needed to speedup compound versus compound.

Refactoring:
...
Moved optional code to Extras: AlgebraicCCD,EPA,quickstep
Moved SimpleBroadphase data to OverlappingPairCache, and derive both SimpleBroadphase and AxisSweep3 from OverlappingPairCache.
Added ParallelPhysicsEnvironment (prepair more parallel mainloop)
Upgraded hardcoded limit from 1024/8192 to 32766/65535 (max objects / max overlapping pairs)

added basic collision filtering, in broadphase. more advanced collision filtering should happen in CollisionDispatch::NeedsCollision

fixed CcdPhysicsDemo: don't pick static objects, it create a point 2 point constraint, which assert in jacobian generation

Allow multiple meshes to be used in the TriangleIndexVertexArray (this name is bad, is should be 'MeshArray'.

Renamed some 'box' into 'convex' in ConvexConcaveCollisionAlgorithm (it is generic for all convex objects, not for boxes).

enable to suspend and restore dynamics. also, catched the case where failed dynamics (resulting in infinite AABB sizes) doesn't mess up the entire simulation, it just get's deactivated (with a message that a simulation error happened)

this should not be necessary, but it happened. todo: why doesn't gjk terminate. there are 2 rare cases, one with 'nan'/undefined separating axis/distance, and another with rather big distances.
