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.
in VoronoiFractureDemo (store intermediate values in memory to avoid problems)
@todo: rewrite the island management to avoid sort for better performance
Thanks to Peter Kyme for the report, fixes Issue 607
fix in infinite recursion in quickSort, exclude the pivot in each sub partition
disabled constraints don't merge simulation islands, and they don't disable collision between linked rigid bodies either.
Enable #define BT_ALLOW_ARRAY_COPY_OPERATOR in Bullet/LinearMath/btAlignedObjectArray.h to re-enable it
Fixes Issue 564, thanks to Tissen Peter for the report/fix
Thanks majestik for reporting the issue and providing a patch, see Issue 469
Fix bug in findBinarySearch, luckily this method was not used yet.
Thanks snowcat for reporting a fix for this issue:
http://bulletphysics.org/Bullet/phpBB3/viewtopic.php?f=9&t=6294
Added assert to check for positive masses in btCompoundShape::calculatePrincipalAxisTransform, see Issue 399
Fixes for LLVM/GCC compilation issue in btSequentialImpulseConstraintSolver
(Untested) fix for Linux 64bit compilation Issue 409
Tweak the BenchmarkDemo a bit:
1) disable deactivation in graphical mode
2) add some settings that increase performance in the BenchmarkDemo2 (1000 stack) from 35ms to 15ms on this quad core (at the cost of a bit of quality)

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
- replaced all usage of heapSort by quickSort
- finished btMultiSapBroadphase. Still some work to be done to increase performance (faster add/remove from child broadphases.
uses currently AABB tree to locate child broadphase (should use grid), and sorted array takes too much time.
- added bt32BitAxisSweep3, which co-exists without recompilation, using template class. This broadphase is recommended for large worlds with many objects (> 16384), until btMultiSwap is finished.
- Fixed some recent issues in Bullet 2.57 related to compound (thanks Proctoid) and memory allocations
Same interface but less features (push_back, pop_back, clear, size, [] etc).
To prepare for SIMD/SSE code: Added #define ATTRIBUTE_ALIGNED16(a) __declspec(align(16)) a
