3f372af486 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.

eafbe063be IMeshManipulator::transform can now also normalize normals
Also only update normals now using inner 3x3 matrix (same result usually as last column is 0,0,0 but faster)
And adding some comments.

3285a0147a a) debug Camera Matrices. enable with _IRR_COMPILE_WITH_90_DEGREE_CAMERA.
- allow ICameraSceneNode to accept any values and correct in buildCameraLookAtMatrixLH with normalize_camera_direction.
 if disabled defaults to the current v1.9 normalize
b) add initial Rotation to MayaCamera Constructor default 0,0
c) switchToMayaCamera in Examples. Clones FPSCamera default disabled

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.

ffd7b63af0 API BREAKER: Replacing defines in irrTypes.h which are conflicting with c++ reserved identifier rules.
C++ has undefined behavior for identifiers starting with __ or with _ followed by an uppercase letter.
We still have many more (in IrrCompileConfig.h and in all header-guards), will likely replace those later as well.
As a workaround for users which might use irrlicht defines in their code, I've added the header irrLegacyDefines.h
Including that allows to continue using old defines for a while - or make it easier to have code which compiles 
with old and new Irrlicht library versions.
