c4db79791c Improve the loading of serialized Bullet files, so that 
after 'loadFileFromMemory' you can save the existing memory back to disk converted to native architecture endianness.
Fixed a bug that prevented big endian machines to load cloth data (due to wrong endian swap of pointer array)
Also improved the 'preswap' so that you can swap endianness on big endian machines (to little endian)

79989a8d3d Force spuNodeCallback to be 16-byte aligned, so that we can use SIMD. Related to Issue 657 
Recompute the quantization values in case the maximum/minimum extends roundtrip using quantize/unQuantize are out-of-range
(alternatively, pass in a larger quantizationMargin)

79a792913d Add the option BUILD_MULTITHREADING to CMAKE, only enabled on APPLE and MSVC platforms. This controls multi-core (BulletMultiThreaded), MiniCL, DX11 and OpenCL acceleration. 
On other platforms (Linux) it might work, but it is unsupported.

60bf599246 perform GrahamScanConvexHull2D around an arbitrary oriented 2D plane in 3D, to fix some convex hull face merging problems 
add compound shape support to BulletXmlWorldImporter and fix some compile issue under Debian (hopefully)
object picking change in the demos: create a ball-socket picking constraint when holding shift while mouse dragging, otherwise a fixed (6dof) constraint
add assert in constraint solver, when both objects have their inertia tensor rows set to zero
btPolyhedralContactClipping: add edge-edge contact point in  findSeparatingAxis (similar to the default GJK case)

(for implicit capsule, cylinder and cone shape)

7eebb79ced implemented rolling friction, using a contact constraint. Useful to get rolling spheres to rest, even on a slightly sloped plane. 
See http://www.youtube.com/watch?v=RV7sBAsKu4M and Bullet/Demos/RollingFrictionDemo
Fixes in FractureDemo (mouse picking constraint needs to be removed, otherwise constraint solver crashes/asserts)

54744b6ab9 added gyroscopic force option for btRigidBody, body->setFlags(BT_ENABLE_GYROPSCOPIC_FORCE); 
Note that it can easily introduce instability at regular (60Hertz) simulation steps so it is generally best to not use the option.
If needed, use a very small internal step, such as 1000 Hertz (world->stepSimulation(dt,100,1./1000.f); or stepSimulation(1./1000.,0);
