Fix T50104, Race condition in SVMShaderManager::device_update_shader

Math Lib: avoid temp array for rotate_m4

No need to have temp array storage, avoid 2x loops.

Math Lib: rotate matrix cleanup

- Remove 'rotate_m2', unlike 'rotate_m4' it created a new matrix
duplicating 'angle_to_mat2' - now used instead.
(better avoid matching functions having different behavior).

- Add 'axis_angle_to_mat4_single',
convenience wrapper for 'axis_angle_to_mat3_single'.

- Replace 'unit_m4(), rotate_m4()' with a single call to 'axis_angle_to_mat4_single'.

Remove eekadoodle workaround for add torus

This is no longer needed since moving to MPoly/MLoop data structure.

Also use 3x3 matrix for transforming instead of quaternion
(slightly better performance).

Fix Torus default UV's offset outside 0-1 bounds

When major/minor segments didn't fit evenly into 4,
the UV's would move outside the UV bounds.

Cycles: Avoid divisions by zero in volume sampling code

Was giving huge artifacts in the barber shop file here in the studio,

Maybe not fully optimal solution, but committing it for now to have
closer look later.

Fix spelling in Cycles distance culling description.

Fix T49718: Wrong "Make Duplicates Real" behavior with "Keep Hierarchy"

All objects were being parented to a single instance of each parent
object, instead of their respective instances, when using dupliverts or
dupligroups.

Behavior was caused by the `persistent_id[0]` (vertex/face id) being
ignored when computing `parent_gh` hash, which caused all instances to
have the same hash, and thus only the first one was included.

Cycles: Fix strict compilation warnings

Should be no functional changes.

Install_deps: fix warning message not showing up in case build fails.

Kinda stupid, but big nice warning about need to try clean build if
something fails was only showing in case install_deps completed
successfully... :P

Fix missing conversion of uchar color to float

Decided to just pass float [4] args, so no type conversion is needed at all.
