BLI_rand: add BLI_rng_get_float_unit_v2

Editmesh: remove redundant normal calculation call for subdivide

UI: remove OpenGL calls from ED_region_init, now handled elsewhere

Replace sqrt with hypot for wipe-effect & transform code

Math Lib: mat3_to_eulo2 & mat3_to_eul2 mixed float/double differently

replace sqrt with hypotf to avoid precision loss instead

Quiet warning in Cycles

Rename 'Extend Vertex' to be clear it operates on many vertices

Comment unused macro

Polyfill2d: use kd-tree

Simple search for intersections became slow for larger concave ngons (100+)
Tested to work with ngons up to 75k sides, performance is approx ~6x faster then scanfill.

This is a 2D version of BLI_kdtree with modifications:
- nodes can be removed
- an index -> node map is stored (especially for tessellation)

Polyfill2d: avoid calculating polygon winding (its known in all cases)

Polyfill2d: Switch directions on concave triangles

Better topology and minor speedup

Polyfill2d: replace array with linklist, faster resizing

approx 4.0x speedup

Cycles: Add support for uchar4 attributes.

* Added support for uchar4 attributes to Cycles' attribute system.
* This is used for Vertex Colors now, which saves some memory (4 unsigned characters, instead of 4 floats).
* GPU Texture Limit on sm_20 and sm_21 decreased from 95 to 94, because we need a new texture for the uchar4 attributes. This is no problem for sm_30 or newer.

Attempt to fix sign conversion error happening on buildbot

Implement GLSL code for XYZ nodes.

Follow up for previous commit: need to tweak args for scons as well

OSX: update codesigning rules to 2.71

Cycles: Fix compilation error of AVX2 kernel with GCC/Clang

Code cleanup.

Cycles: Add an AVX2 CPU kernel.

This kernel is compiled with AVX2, FMA3, and BMI compiler flags. At the moment only Intel Haswell benefits from this, but future AMD CPUs will have these instructions as well.

Makes rendering on Haswell CPUs a few percent faster, only benchmarked with clang on OS X though.
