Use qsort_r for BMesh Py API

Cleanup: pep8

Trade-marked BPlayer Fix (c)

Fix T45258, impossible to select brush when removing it from 2d
painting.

Also system added a brush every time it found no paint brush in the
system which is not what we would want.

Solution:
* Brush panel stays visible always, regardless of whether there is a
brush or not.
* We search for first available brush when we find no brush in paint
struct instead of always generating a new one.
* Generating and searching for a brush take a mode argument now. Needed
some refactoring to users of BKE_paint_init as well.
* Did some style cleanups for paint mode enums.

Patch is big but it's mostly argument refactoring.

Fix T45954: Inset w/ interpolated vertex color

Accumulating ubyte color was overflowing.

Thanks to @mont29 for suggested fix.

Cycles: Make the max value for World MIS Map Resolution a power of two.

Old value likely was a copy / paste error.

Cleanup: Fix some typos in volume code comments.

Write thumbnail directly

BlendThumbnail matches the on-disk format, so just write directly.

Fix T45955: Python's pdb can't show script source

Revert fix for T45849 (part 2, tsk!)

Alternate fix for T45849: tri-tri intersect error

Project both triangles onto the same plane to simplify calculations.

Revert fix for T45849, alternate fix coming up

epsilon check here didn't account for scale, causing T45919

Math Lib: Add closest_to_plane helper functions

- closest_to_plane3 (for float3 planes)
- closest_to_plane*_normalized_v3 (for unit length planes)

Use when the plane is known to be unit length

Fix T45959: DistanceKey output incorrect

Fix uninitialized vars in DistanceKey node

Fix incorrect cast

Cycles: Avoid copying objects in some places of BVH build

Gives barely measurable speedup of Spatial Split BVH build.

Preview generation module: explicitly exclude any lib item.

Thanks to campbell for raising that point!
