Cycles: Sort tiles in rendering order at construction time

This commit modifies the TileManager to sort render tiles once after tiling the image,
instead of searching the next tile every time a new tile is acquired by a device.

This makes acquiring a tile run in constant time, therefore the render time is linear
w.r.t. the amount of tiles, instead of the quadratic dependency before.

Furthermore, each (logical) device now has its own Tile list, which makes acquiring
a tile for a specific device easier.
Also, some code in the TileManager was deduplicated.

Fix bevel RNA enum/boolean mixup

Math Lib: clamp closest_to_line_segment_v# when segment has no length

For a line this makes sense but segments should clamp,
avoids assert in edge-rip.

Fix issue w/ transform orientation & vert selection

Accessing selected verts as an array failed when only
some of the selected verts were in the selection-history.

Remove feof check for file reading

This wasnt correct since we're not reading past the stream,
though it worked on Linux and some Windows systems.

Disable calculating manipulator while transforming

Gives ~10% speedup

Add BM_vert_edge_pair utility function

Fix error in BM_vert_is_edge_pair

Returned true for verts with a single edge.

Typo in last commit

Select Linked: only use seam delimit for faces

Delimiting on seams was only ever intended for face selection,
Previously this option didn't work for vertices,
now it's fixed the defaults aren't right for vertex/edge select-linked.

Add a workaround that bypasses operator-defaults - since this is such a rare case.

Fix T47003: OpenGL draw missing selection highlight when using hidden wire.

Get rid of OMP in MOD_build.

Reasons:
- Only parallelized piece of code gives little local speedup (code block only about 25% quicker even on 1M polys cube).
- No gain nor loss using new BLI_task system.
- At 10% of build, parallelized piece of code is only about 5% of total func runtime (run-time explodes as build proportion increases).

See no point in adding (in utmost best optimistic case, in real use-case, when depsgraph will likely already fire several evaluations in parallel,
speedup would be even smaller) 1% speedup here at the cost of threading complexity...

Note that since later code uses hashes, I don't think it's easy to thread it, so think we can leave with it for now.

View3D: measure smoothview angle comparing quat angles

Rolling the view registered as no angle-difference.

View3D: Rotate around selected support for view-roll

Fix T31605: Nupad ignores Rotate around selection

Add support for smooth-view orbiting a point besides the view center.

Fix error orbiting out of camera + orbit-selected

Would use the wrong view center (that wasn't update from the camera).

View3D: use c99 compound literals for smoothview params

Smooth-view functions took many arguments which were often NULL,
now take struct instead.

Cleanup: Remove comments, now that we have the dedicated constant fold functions, it's obvious.

Cycles: Constant fold for the Gamma Node.

Rename mesh operators

- use 'Intersect' prefix for boolean and regular intersection.
hints that they use the same basic logic with different modes.
- 'split by edges' while correct - isn't very descriptive.
