196aa20329 add m_splitImpulseTurnErp solver setting, initialized to 0.1: more stable recovery from deeper penetrations by reducing the angular effect (if split impulse is enabled) 
Set it to 1.0 to disable the effect.
removed broken/not maintained heightfield fluid demo
add some API methods to btPersistentManifold

84b1774dda improve handling of restitution by using the velocity (linear/angular) before applying forces: this is done by re-introducing the btSolverBody and only apply the forces to solver body, and use the original rigid body velocity for restitution computation. 
warmstarting for contact points was broken, fix in btPersistentManifold
enable split impulse by default (at the cost of some performance)
add  the option for zero-length friction (instead of recomputing friction directions using btPlaneSpace), use the solver mode flag SOLVER_ALLOW_ZERO_LENGTH_FRICTION_DIRECTIONS
precompute lateral friction directions (in btManifoldResult)
remove the mConstraintRow[3] from btManifoldPoint, it just took a lot of memory with no benefits: fixed it in btParallelConstraintSolver

10ed7bffd5 Fix serialization issue with btGeneric6DofSpringConstraintData, due to typo 
Skip btGeneric6DofSpringConstraintData parts of the data that will be invalid in .bullet files version 280 or older
This fixes Issue 618, thanks to cyrfer for the report.
minor improvements in premake build (name library output so multiple Visual Studio installations don't conflict)
remove msvc folder

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.

b5b31ce52b added VoronoiFractureDemo, thanks to RBD 
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.

654fe7872a remove btContinuousDynamicsWorld, it is obsolete and was never completed. 
If you need tunneling prevention, one option is to use the CCD motion clamping in btDiscreteDynamicsWorld. See also Bullet/Demos/CcdPhysicsDemo.
You can use an embedded sphere that prevents tunneling, using the following settings:

		body->setCcdMotionThreshold(0.5);
		body->setCcdSweptSphereRadius(0.9f);
