Each time we setted the mass the own object gravity was divided by its
old mass (i.e you could convert you car in a flying DeLorean with a
simple mass car modification).
A note will be included in release notes due to retro compability
issues.
Actually we only have a Python API that allows to change the max jumps value.
The patch also allows non programmers to change the maximum numbers of jumps.

* Change the character jumping variables and methods from int to char.
* Limit the maxJumps integer value from 0 to 255.
* Allow to set the minimum jump amount to 0.

This patch makes it possible to zero out angular velocity. tiny angular
velocities may cause instabilities, according to the discussion in T41943,
so they are mapped to (0, 0, 0) instead.
It also applies the same reasoning to the linear velocity, unifying the
different approaches.

Fixing crash if the physic type is set sensor or character. Caused by a790e172d0.
Fixing memory leak, if the constraint is deleted with Python API removeConstraint().
Add RemoveConstraint() method to avoid code duplication.
Rename old RemoveConstraint() to RemoveConstraintById() which is more suitable name for this method.
The issue was caused by the following construction:
def = env['SOMETHING']
defs.append('SOMETHING_MORE')
Since first assignment was actually referencing environment option it was totally
polluted hawing weird and wonderful side effects on all other areas of Blender.
Constraint on soft bodies are special and return 0 as constraint id.
So we have to check that the id is not 0 in function setParam, getParam, getAppliedImpulse and removeConstraint.
Angular velocity clamping was missing from the BGE. It is implemented
similarly to the linear velocity clamping. It is needed to be able to
drive physical simulations of systems that have a limited rotational
speed.

Currently we can't update the physics mesh of an added rigid body.
The cause is that that we need to update all shapes to say that the mesh was changed, for static object we don't do that previously because we use a odd way to reallocate memory at the same place.
So now when a mesh is changed we iterate all physics controllers which use the same shape info and recreate its shape with the correct mesh.

Currently there are bugs with physics objects in inactive layers,
character and softbody.
I added a function in CcdPhysicsEnvironement to know if a physics
controller is currently active and for soft body I added the correct function in UpdateCcdPhysicsController to re-add a softbody in the dynamics world.

A Python API for the collision group / mask has been added:
```
KX_GameObject.collisionGroup
KX_GameObject.collisionMask
```
The maximum number of collision groups and masked has been increased from eight to sixteen.
This means that the max value of collisionGroup/Mask is (2 ** 16) - 1
EndObject will now activate objects that were sleeping and colliding with the removed object.
This means that, unlike now, if a rigid body starts sleeping on top of another object, when the latter is removed the rigid body will activate and fall, rather than float midair as before.
Collision groups that do not intersect used to collide on the first frame. Now this has been fixed so that they collide appropriately.
Thanks to agoose77 for his help.

Two areas of the BGE use a hard-coded 60 Hz as frame rate. However, this 60 Hz is just a default setting, and can be changed in the Blender interface.
This setting is now used instead of the hard-coded 60 Hz.
CcdPhysicsEnvironment::SetFixedTimeStep() is actually never called, as we don't even support a true fixed-timestep simulation.
Blender allows you to create a constraint without specifying its reference
object, even when the constraint requires such a reference. The BGE would
crash on this. This change simply ignores such a constraint.
Deleting an object was deleting all rigidbody constraints in the scene.

This patch adds two parameters to the functions in the
collisionCallbacks list. The callback function should thus be like
this:
```
def on_colliding(other, point, normal):
print("Colliding with %s at %s with normal %s" % (other, point, normal))
game_ob.collisionCallbacks.append(on_colliding)
```
The `point` parameter will contain the collision point in world
coordinates on the current object, and the `normal` contains the
surface normal at the collision point.
The callback functions are checked for the number of arguments
`co_argcount`. The new `point` and `normal` arguments are only passed
when `co_argcount > 1` or when `co_argcount` cannot be determined.
