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)

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);

Avoid using restitution for ccd motion clamping.

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
