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.
This patch fix two bugs related to CreateConstraint().
1. Disable linked collision only working with 6DoF constraints.
2. If all pivot axis rotations setted to zero the linked object disappears.

OpenGL is detected:
Hoping to decrease the frequency of by far one of the most frequent bug
reports by windows users.
There is some reorganization of the GHOST API to allow easy addition of
further OpenGL options in the future. The change is not propagated too
deep to keep the size of the patch managable. We might reorganize things
here later.
For OpenGL we do two checks here:
One is a combination of GDI generic renderer or vendor microsoft
corporation and OpenGL version 1.1. This means the system does not
use GPU acceleration at all. We warn user to install a graphics
driver and of cases where this might happen (remote connection, using
blender through virtual machine)
The other one just checks if OpenGL version is less than 1.4 (we can
easily change that in the future of course) and warns that it is
deprecated.
Both cases will still let blender startup correctly but users should now
have a clear idea of the system being unsupported.
A user preference flag is provided to turn the warning off.
Now stop posting those bug reports without installing a driver first -
please?
Deleting an object was deleting all rigidbody constraints in the scene.
Bug was introduced with D701.

New Lock Z velocity parameter was added. This parameter avoid the micro-jumping.
By default it is actived except when you load an old file that it is deactived to keep former behaviour.
Additionally it was solved another issue related with the acceleration: That is the acceleration value was not taked into account and we had always the maximum linear velocity from the beginning of movement. Now the acceleration is taken into account until we reach the maximum velocity.
When you load an old file, the acceleration value is set to the maximum range (1000.f). This way we simulate a maximum velocity constant from the beginning of movement (former behaviour).

Due to changes in the way animation updates were handled,
BL_ArmatureObjects were no longer registering to KX_Scene as animated.
Moguri says: It might have been relying on the deformer update which
moved rom being called on every object in the render step. Now
armature deformers are only updated if they need to be.
Fix T42919 & Fix T42218
We make sure that good values are passed to GetPolygon() and we check that the visual mesh doesn't have a wrong displacement when it passes over a object which has a mesh triangle as compound bound.

All of the initXPythonBinding functions are changed to always creating the module instead of importing if previously existing.
I can instead only remove the module return when the import is ok, so that it always inits. But then, I don't see the point in importing.
I make sure that these functions are called only once per run, inside initBGE.
This was not the case with GameTypes. I moved initPyTypes inside of initGameTypesPythonBinding due to that.
I reorganized initGamePlayerPythonScripting and initGamePythonScripting so that they run things in the same order.
initGamePlayerPythonScripting imports mathutils and aud, the other only aud. Shouldn't it be the same for both?

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.

The goal of these changes is to Close T40132 and to get rid of the 'PyRun_SimpleString'
Hilighted changes are:
- consistent naming and initialization of BGE submodules
- initialization of the 'bge' module as a proper module
- using PyDoc_STRVAR instead of static char*
- generic cleanup (unused arguments, logica ordering, naming and whitespace)

This function allows the user to run specific code for each of the
rendered stereoscopic eyes in the Game Engine.
The initial use case is to set the camera projection matrix in
a scene.pre_draw callback function for each eye, to be used in VR
(Virtual Reality) installations.

Refactored some code to be easier to read. Semantically the code is
identical.
- Some conditions were negated to be able to return/continue early,
rather than having the majority of the code inside an if-body.
- Conditions were simplified (!(a == b)) turned into (a != b);
repeated conditions calculated only once.
- Unnecessary variables and one unnecessary condition were
eliminated.
