7ecaa18949 Merging r6506 through r6510 from branch releases/1.8 to trunk
Note those were mostly backport, so trunk already had most changes.
Also we've not merged all from 1.8 branch, will need another merge (backports tend to cause lots of ugly conflicts, so have to split this a bit)

c4504c1d48 Add IMeshSceneNode::setNodeRegistration to allow registering MeshSceneNodes to the SceneManager per buffer instead of per node
So far SceneManager always sorted Nodes per render stage.
Now we allow sorting per mesh-buffer per render stage by creating a new node for each mesh-buffer.
It's only supported for CMeshSceneNode so far.

This allows to enable better transparency sorting for meshes which have transparent buffers.
Previously those always got rendered in the order in which they got added and ignored mesh-buffer bounding-boxes, but just used the bbox of the full mesh. Now they can use the bbox for each meshbuffer which can sometimes avoid render errors.

Also depending on the scene this can be quite a bit faster because it can help reduce texture changes. We sort solid nodes per texture, but only per node. So nodes with several textures had a texture switch between rendering each meshbuffer. And those are rather expensive in Irrlicht right now (and we support no bindless textures yet...)

Lastly it's now also used to buffer the render-stage. Checking this twice (once in registering the node and once in render) constantly showed up in the profiler. Which was a bit surprising really, but anyway - now it's gone.

I tried to keep it working for all cases we had before (all kind of situations, like when people may want to call render() outside the SceneManager). But not (yet) supporting the case of changing the meshbuffers (adding or removing some) without calling setMesh() again. Reason is that this wasn't well supported before either (node materials never updated). So for now I just assume people will call setMesh() again when they change the mesh.

b627ce805d Add option to allow nodes to ignore the scale/rotation parts of their parents transformation.
ISceneNode::setUpdateAbsolutePosBehavior can now control what ISceneNode::updateAbsolutePosition really does.
Having only the position and not the rotation/scale of a child node affected by the parent transformation was previously impossible inside the scene-graph. So people always had to break the scene-graph and code it themselves.
Old behaviour is default. 
Extra check for new variable has a small cost, thought new behaviour can actually be faster when it's used.

71e9798d2a Add IMeshBuffer::getType
Allows to find out which class a meshbuffer has.
I used the same kind of style as ISceneNode::getType. So using four CC codes and virtual functions (instead of type variable).

3d2a55e788 Replace header guards in source folder to avoid using identifiers reserved by c++
Basically fixing original Bug#427 reported by MArkus Elfring.
Unfortunately there are still more defines (in IrrCompileConfig.h) which also are not nice c++
Lots of files touched for very minor cleanup *sigh*

0c6385cb92 Replace public header guards to avoid using indentifiers reserved by c++
Usually something like __IRR_SOME_GUARD_INCLUDED__ replaced by IRR_SOME_GUARD_INCLUDED.
Removing underscores at the end wasn't necessary, but more symmetric (probably the reason they got added there as well).
While this touches every header it shouldn't affect users (I hope).

Also a few whitespace changes to unify whitespace usage a bit.
And a bunch of spelling fixes in comments.
