Stop adding motion in the kinematic character controller if the walk direction is near zero
Auto limitation of spring stiffness and damping in btGeneric6DofSpring2Constraint is now optional. Fix: spring stiffness limitation used the mass incorrectly in btGeneric6DofSpring2Constraint.
maintain backward compatibility using BT_ENABLE_GYROPSCOPIC_FORCE = BT_ENABLE_GYROSCOPIC_FORCE_IMPLICIT_BODY
further work on shared memory API fix dependency of BulletDynamics to Bullet3Common (b3Printf)
_N -> n, _C -> c, _L ->l, some collision with a standard C++ header?
remove a lot of warnings (more todo in demos and serialization code)
fix Linux and Cmake build
premake: use *.cpp insteadl of **.cpp
