1aac33f6b6 refactor constraint serialization, so that double precision is maintained,
changes are backwards compatible (btBulletWorldImporter can load old .bullet files)
but not forwards compatible (constraints in new .bullet files are ignored/unrecognized by old Bullet SDK)
This commit is for Issue 734. Some more work needs to be done for btGImpactMeshShapeDoubleData and thus btStridingMeshInterfaceDoubleData and btMeshPartDoubleData

9abd0b6029 Sorry for the lack of updates, I am preparing Bullet 3.x initial release and get back to merging Bullet 2.x and Bullet 3.x afterwards.
fix some crash in btSoftBody, related to running out-of-memory. You can configure the default maximum memory allocation for the signed distance field using worldInfo->m_sparsesdf.Initialize(hash, maxAllocation);
fix 'exploding' btSoftBody, related to very small masses. You can configure maximum displacement per frame using worldInfo->m_maxDisplacement 
avoid some crash in the world importer

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)

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.

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.

Fix in btBulletWorldImporter: load friction/restitution and patch radius of btCapsuleShape (it needs to embed the margin)
Partly apply a modified patch to make the SerializeDemo_AMD work, but avoid breaking the MiniCL version. See Issue 594

6173a30bce Improved BulletSoftBody serialization, added cluster support. Joints and copying data from GPU back to softbody are the main todo.
Updated the Bullet/Demos/SerializeDemo to load .bullet files with the softbody data.

BulletSoftBody should use getWorldTransform and not getInterpolationWorldTransform
Fix btBulletWorldImporter so that it creates a copy of the index/vertex data, this prevents crashes when deleting the .bullet file with triangle meshes.

032c6bfe2c add initial support for soft body / cloth serialization, and updated SerializeDemo to load soft bodies/cloth.

8fbe399ea4 Make .bullet serialization mode robust:
Deal with broken DNA serialization. Bullet 2.76 release revision 2035 - 2046 was broken, and this includes the Maya Dynamica plugin.

40dc18f604 remove Extras/obsolete/quickstep
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

41e9115bca Add support to serialize btOptimizedBvh/btQuantizedBvh for a btBvhTriangleMeshShape (using the new btSerializer). This is a new implementation, with full cross-platform support.
So it is different from the in-place method (btQuantizedBvh::serializeInPlace/deserializeInPlace).

It is also possible to serialize/deserialize just the bvh, using the btSerializer (needs some code snippet/helper)

ee3e231be5 + more consistent 'setLocalScaling' for the btCompoundShape. Full non-uniform scaling is not supported when child shapes have a rotation. If any child shapes have rotation, the best you can do is either uniform scaling, or 'baking' the non-uniform scaling into the child geometry (vertices of a convex hull for example)
+ fixed an issue with BulletWorldImporter, btBoxShape implicitShapeDimensions already includes local scaling.
