Ceres: upgrade to version 1.3.0

This should contain real fixes for Windows, making it more robost and hopefully
faster (due to proper collection port) on that platform.

Also hack to fix Eigen alignment shouldn't be needed anymore.

Also on platforms which have got broken TR1 collections it's better to define
CERES_NO_TR1 instead of using Boost hacks. Made changes to Scons and CMake,
but can not check if this indeed works since i don't have OSX here.

Ceres: remove debug-only code from bundling script, also move osx workaround to template

Code cleanup - Remove/update outdated comments and whitespace tweaks

use the format attribute in more places, disable X11 options when building with GHOST_SDL

speedup for vertex parent lookups, were looping over array elements when it wasn't needed for lattice and curves, and in some cases meshes.

do dirrect array lookups instead where possible.

Bugfix [#32501] Protected layer bones transform buttons are greyed out/inactive

Since the transform values for bones in protected layers can be animated again
using many of the common tools, it makes sense that the transform properties for
these are allowed to be edited too.

I've left the rotation mode setting as a "proxy locked" value for now, since
this seems more like something that's defined as part of the rig creation (and
best left alone by animators).

Code cleanup - remove some obsolete code

style cleanup

fix for error in recent commit (made function static that shouldn't have been), add extra gcc warnings to cmake.

code cleanup: quiet warnings for gcc's -Wundef, -Wmissing-declarations

code cleanup: make local game engine functions static

code cleanup: remove unused structs and also some style cleanup.

remove unused parts of raskter module.

Yet another OSL fix: Some functions are missing stubs that were not used in old OSL implementation yet.

Fix for OSL 'Normal' node: the Direction parameter is of 'normal' type instead of generic 'vector'.

Generate compatible OSL shader parameter names in cases where the node has and input and output with the same name. In that case the convention is to add suffixes "In" and "Out" respectively.
Example:

Blender node has one input "Color" and one output "Color"

-> OSL parameter names should be "ColorIn" and "ColorOut"

OSL implementation of RGB ramp node.

The sampled color ramp data is passed to OSL as a color array. This has to be done as actual float[3] array though, since the Cycles float3 type actually contains 4 floats, leading to shifting color components in the array.

Additional parameter set functions for arrays have been added to the Cycles OSL interface for this purpose.

Merged this part of code by mistake.

Cycles / OSL:
* Fix Musgrave Texture, used wrong Perlin Noise (0..1) instead of -1..1. Also added comment to noise_basis() to make it clear which noise type is used there.

Cycles / OSL:
* Fixes for Voronoi, Gradient and Magic Textures. SVM and OSL renders excactly the same now.
