85a3cb0ed5 Add ability to get the original vertex index from the convex hull (#3018) 
This makes it possible to know which input verticies were picked to
to define the hull.

With this information it is much easier to map certain features from the
input mesh/point cloud to the output convex hull.

c517c434e6 pybullet allow to enable/change joint limits: 
pybullet.changeDynamicsInfo(objectUniqueId, linkIndex, jointLowerLimit=..., jointUpperLimit=...) # jointLowerLimit <= jointUpperLimit

and joint limit max force:
pybullet.changeDynamicsInfo(objectUniqueId, linkIndex, jointLimitForce=...)

For example:
p.changeDynamics(sphereUid,linkIndex, jointLowerLimit=1, jointUpperLimit=3, jointLimitForce=10.5)

add b3ChangeDynamicsInfoSetJointLimit/b3ChangeDynamicsInfoSetJointLimitForce
add getConstraintType for btMultiBodyConstraint

2197101bc5 Fix parameter check in bFile::safeSwapPtr 
If either the source or destination pointers are nullptr, we shouldn't continue otherwise we dereference nullptr or memcpy with nullptr which is undefined.

(Also move the check to return as soon as possible.)

e6a0206d47 Allow to remove soft body anchors, using pybullet.removeConstraint (untested). 
Usage example:
anchors = []
anchors.append(p.createSoftBodyAnchor(clothId  ,0,-1,-1))
anchors.append(p.createSoftBodyAnchor(clothId ,3,boxId,-1, [0.5,-0.5,0]))
for a in anchors:
  p.removeConstraint(a)
