Avoid undefined arithmetic on nullptr in buffer_offset function
Not quite sure why it was done that way. Maybe to ensure we work with byte-pointers of correct size or something?
Anyway, this doesn't seem to be defined in c++, so let's try working with a cast instead.
Just something cppcheck tool complained about.

Fix some problems with CMatrix4::getRotationDegrees
- Only the getRotationDegrees without parameter is allowed to try fixing scale.
My fault when I added a new function which takes scale parameter, that one is
not allowed to be changed.
On the up-side - we know have for the first time an option which works in cases only
scale and rotation had been used and the user still has the correct scale.
Before any solution for that was broken
- getRotationDegrees fixes 2 places which caused wrong results due to floating point inaccuracies
New test for that got added
- Document the current restrains and problems of getRotationDegrees and getScale some more.
- Improve docs for other matrix4 functions.
- Add some comments about further improvements (I'll try if I find time)
Note: Irrlicht still assumes in at least 2 places (getting bone animations and Collada loader) that matrix
decomposing works. Which it doesn't yet for matrices which switch handedness (or have further transformations like skewing axes)
The bone animation is mostly fine for now with recent workaround (but that might cause other problems as it may be used too often), haven't checked Collada yet in detail.
TL/DR: This improves things with getRotationDegrees, but does not yet fix all troubles.

Avoid some broken calculations for IBoneSceneNode positions.
This is based on bugreport #458 reported by viwrap who also made a nice test-case model.
Note: While solution seems to work and would even be faster, I'm not 100% sure yet if there are no downsides.
The other solution seems to regard last column in matrices - thought I don't think we ever set or use that.
And I also haven't found out yet _why_ the original solution goes wrong.
But animation system uses right-hand quaternions unlike rest of Irrlicht which is obviously a bit dangerous, will have to check the conversions some day.
Fix: Make CBillboardSceneNode bounding-box large enough to fit the billboard inside.
It still won't work yet for scaled boundingboxes (or parents being scaled).
But at least it's now large enough for typical unscaled boundingboxes.
Before it was always too small - even for the simplest quadratic billboard case seen without rotation.
Now it's always a bit too large, but that's way less of a problem (collisions still work and culling simply happens a bit less often, but not too often which is way worse)
Fix IGUIElements not getting a tab order because of invisible or disabled parents.
First problem was that IGUIElement::getNextElement wasn't passing includeInvisible and includeDisabled flags recursively, so anything deeper than one level could fail if an element was disabled/invisible in between while it was created.
Second problem was that setTabOrder(-1) did ignore disabled elements. So when any parent was disabled when elements were created they never got a tab order.

Unify & improve log messages
Lots of places where coders did not realize our Printer::log with hint adds a ": " string between message and hint
Which caused uglier messages in a few places (added documentation for that, maybe helps?)
Some added info in a few places
Some whitespace unification
Some spelling unification
S3DVertex initialize color always. It's derived classes now both accept const S3DVertex& constructor.
color intitialization has some cost, but we initialized all other values already (vectors are always set to 0).
Don't think it's a good idea to have one value around which is random.
S3DVertex2TCoords(S3DVertex& o) to S3DVertex2TCoords(const S3DVertex& o) simply because it makes more sense
S3DVertexTangents(const S3DVertex& o) added because I'll need it later (and no idea why only S3DVertex2TCoords got one of those before).

IVideoDriver::setMaterialRendererName now using u32 for index like other similar functions
Other functions like getMaterialRendererName got switched to u32 in the past. I can see no reason why this one was left out, so changing it to be same as the rest.

Replace _IRR_OVERRIDE_ macro with override keyword
The commit also establishes a precedent of leaving off the `virtual`
keyword in overrides. Although not strictly necessary, I believe this is
good for readability because it makes it clear it is an override and not
a pure virtual function, and it helps keep line lengths shorter. We
should move towards eliminating the macro altogether, but the definition
has been left in with a note on deprecation so that in-progress work
will not suffer merge conflicts.
