Making the reference argument optional for the addObject function.
```
scene.addObject("Cube")
```
This allows to keep the rotation, scale and position of the original object.
To avoid layer problems with lights if the reference arguments is None, the new object have the same layer than the active layers in scene.

This callback allows the user to change the camera data right before the
rendering calculations.
scene.pre_draw[] is not enough here, because if you want to change the
camera matrices (projection/modelview) the culling test is done before
that (after pre_draw_setup[] though).

Python sample code using this. The sample scene would need a default
camera (not used for rendering), a dummy camera ('Camera.VR'), and two
cameras ('Camera.Left', 'Camera.Right') that will be used for the actual
rendering.
```
import bge
def callback():
scene = bge.logic.getCurrentScene()
objects = scene.objects
vr_camera = objects.get('Camera.VR')
if bge.render.getStereoEye() == bge.render.LEFT_EYE:
camera = objects.get('Camera.Left')
else:
camera = objects.get('Camera.Right')
vr_camera.worldOrientation = camera.worldOrientation
vr_camera.worldPosition = camera.worldPosition
def init():
scene = bge.logic.getCurrentScene()
main_camera = scene.active_camera
main_camera.useViewport = True
scene.pre_draw_setup.append(callback)
objects = scene.objects
vr_camera = objects.get('Camera.VR')
vr_camera.useViewport = True
vr_camera.setViewport(
0,
0,
bge.render.getWindowWidth(),
bge.render.getWindowHeight() )
```
A new function (RunPythonCallBackList) to call all python functions
contained in a python list was developed.
This function has:
- first argument is the python list of callbacks
- second argument is a python list of arguments
- third argument is the minimum quantity of arguments
- forth argument is the maximum quantity of arguments
It improves flexibility and supports *args.

KX_Scene::addObject: Changed the parameter "other" to "reference", as "other" doesn't mean anything.
KX_Scene::AddReplicaObject: Changed the parameter "parentobject" to "referenceobject", as the parameter did NOT contain a parent object in any way.
Now both functions use the same kind of name for the same thing.
Thanks to panzergame / Porteries Tristan.
This Patch will add a the world API (mist, background, ambient) to KX_WorldInfo.
The new API uses now attributes.

This change introduces a new hysteresis parameter that it will be added
or subtracted to/from the LOD distance to avoid popping when a LOD
object moves close to the LOD transition continuously.
Then, we have the following:
- a new LOD Hysteresis setting per scene (default 10%) which is located
in Scene context --> Level of Detail panel. This scene parameter also
will active/deactive the scene hysteresis.
- and a new LOD Hysteresis setting per object (default 10%) which is
located in Object context --> Levels of Detail panel. The LOD hysteresis
setting per object (if active) will overwrite the hysteresis setting per
scene value.
For the new blends: the hysteresis setting per scene would be active by
default and the per object would be inactive by default.
For the old blends: both hysteresis settings (per scene and per object)
would be inactive by default. A quick way to take advantage of this
feature for old blends would be to activate the hysteresis parameter in
the scene context -> Level of Detail panel

This patch will add a physics constraints replication for group instances
(dupli group).
It also fix crashing when when a group instance is made from a linked
group instance and both are on the active layer.

Instead of getting fancy this time, we'll just use Mahalin's simpler
fix. This may have slight performance impacts, but it is a lot simpler
than the previous fix and shouldn't cause as many bugs.
Scene replacement with invalid scene name was crashing blender,
now it's a no-op.
KS_Scene.replace() to return a boolean to indicate if the scene
is valid and is scheduled for replacement. This allows more
robust game management.
This is mostly the same fix as before, but now code depending on culling
checks is executed after KX_Scene->CalculateVisibleMeshes(). As a
side-effect, LoD checks and animation culling now use the current
frame's culling information rather than the previous frame's.
Updating object IPOs is not currently thread-safe since it also updates
children. This leads to problems when parents and children are both
animated. For now, updating object IPOs is done in its own loop to avoid
threading issues.
I'm not sure why this function ever increased the object's refcount. Any
place in the code that calls KX_GameObject::GetParent() has to turn
around and call parent->Release(). Forgetting to call Release() was a
common cause of memory leaks (in fact, KX_SteeringActuator was probably
leaking). If the refcount needs to be increased, the calling code can
handle calling AddRef().
There was some deadlock due to trying manage Python's GIL. Instead of
continuing to fight with it, anything needing to call into Python while
conversion during lib loading is just delayed until it can be done in
the main thread.
Our deformer system really needs some work. First, there was a crash
with shape keys because BL_ModifierDeformer derives from
BL_ShapeDeformer, which means we try to execute shape keys even if we do
not have them. Also, for some reason BL_ModifierDeformer::Update() does
not work if called from the threaded loop, so it is skipped for now. In
other words, skinned updates on meshes with modifiers are currently not
run in parallel.
This required BL_ArmatureObject to have tighter control over armatures and poses.
Also, (Blender) armature objects are now copied instead of shared between
BL_ArmatureObjects to avoid race conditions. Also, due to the armature copy,
shape key drivers need a bit of extra fiddling to get the correct armature copy.
Initially OpenMP was used for threading, but then BLI_task was used due to being
less compiler dependent.
This commit also places time spent on skinning updates in the Animation
profiler category (was previously under the Rasterizer category).
The ultimate goal is to only allow the rasterizer to handle OpenGL and bf_gpu
calls. This commit creates a RAS_ILightObject interface and a RAS_OpenGLLight
implementation.
Levels of detail can be added and modified in the object panel. The object
panel also contains new tools for generating levels of detail, setting up
levels of detail based on object names (useful for importing), and
clearing an object's level of detail settings. This is meant as a game
engine feature, though the level of details settings can be previewed in
the viewport.

Armatures used to check if any of their meshes were culled to see if they needed
to be updated. However, this meant armatures with no meshes would never update,
since non-mesh objects are always considered culled. Instead, if a non-culled
child was not found, we now check to see if the armature contained only
non-mesh objects. If this is the case, always update the armature. If this
becomes a problem, we can look into being able to cull non-mesh objects.
