First step in btMultiBody joint force/torque feedback. There is still some work to be done for 'mobilizer limit/motor'.
...
See examples/MultiBody/TestJointTorqueSetup and examples/Constraints/TestHingeTorque for joint feedback.

Introduce kF_UseGjkConvexCastRaytest, and make kF_UseSubSimplexConvexCastRaytest the default for btCollisionWorld::rayTest See https://github.com/bulletphysics/bullet3/issues/34

Add btCollisionObject::setIgnoreCollisionCheck to disable collisions between specific instances, without having a btTypedConstraint. See https://github.com/bulletphysics/bullet3/issues/165
Make btMultiBody and btMultiBodyJointMotor backwards compatible with Bullet 2.82 API (single-DOF API)

Added btMultiBodyPoint2Point, it can be used between btMultiBody vs btMultiBody or btMultiBody vs btRigidBody
...
Allow picking of btMultiBody, using a btMultiBodyPoint2Point constraint, with limited strength to avoid adding too much energy to the system (= blowup)
Add btMultiBodyJointMotor, it can be used in combination with joint limit (just add the joint limit after the motor, to avoid jitter)
