Skin mark/clear: replace GHash with GSet

Fix stupid typo that broke split normal shading in edit mode, when there was some deform modifiers.

Fix incorrect ghash free

GHash, EdgeHash: hint on unlikely branch

also avoid searching buckets for empty hashes

Correct cast from recent bool changes

Code cleanup: correct abs use

also minor cleanup to rotation code

Code cleanup: style

Nodes: make default group nodes slighly wider, to match other node width defaults.

Fix error making datablock with fake user local, the user count would be wrong afterwards.

Math Lib: faster version of rotation_between_vecs_to_mat3

Use axis/angle calculation but avoid calls to sin/cos

BGE: Fixing memory leaks when deactivating Sensors, Controllers, or actuators.

Found by Coverity and confirmed with Valgrind.

Math Lib: add shell_v3v3_normalized_to_dist and v2 version

bypass angle calculation to avoids (asin, sqrt, cos).

Bullet: making bullet friction workaround more furureproof by using the __apple_build_version__ macro, TODO: check if problem persists with newer clang

Minor change to recent commit (avoid transpose)

Math Lib: minor optimization to barycentric_transform

replace rotation_between_vecs_to_quat with axis_dominant_v3_to_m3.

Math Lib: add rotation_between_vecs_to_mat3

- behaves like rotation_between_vecs_to_quat
- avoids calling sin,cos calls (approx 1.6x faster).

Math Lib: minor optimization for axis_angle_normalized_to_mat3

Disable quicktime when in cmake's lite configuration

Cycles: SVM optimization for mix shaders, to skip more code when the mix weight
for one of the input shaders is zero.

This gives about 5% speedup for koro_final.blend. In general this is important
so you can design shaders that run faster for shadows, diffuse bounces, etc, for
example by skipping procedural textures or even using a single fixed color.

Fix cycles using acosf in panorama render when it should use safe_acosf.
