Cycles: Fix compilation warning

Fix T52533: Blender shuts down when rendering duplicated smoke domain

Fix: Deleting GPencil keyframes in DopeSheet didn't redraw the view

Fix: Border select for GPencil keyframes was including those in the "datablock" channels even though those weren't visible

This meant that it was easy to accidentally select too many keyframes

Fix: GPencil Sequence Interpolation for thickness/strength was inverted

For example, if you have two keyframes:
k1 = 1px, k2 = 10px

it was doing:
1px, 9px, 8px, ..., 3px, 2px, 10px
instead of:
1px, 2px, 3px, ..., 8px, 9px, 10px

Fix T52483: Fill is incorrect for interpolated strokes

The recalc flag must be enabled for new interpolated strokes.

BMesh: use predictable order for remove-doubles

Each qsort implementation may give different results when values match.

Now fallback to sorting by index.

Fix T51400: Pasting hex code fails

The # prefix is supported,
the button didn't give enough space to paste it.

Fix T52515: Crash on BMesh.to_mesh()

Fix minor Mesh -> BMesh conversion issues

- Vertex only meshes never restored their selection history.
- Select history was cleared on the source instead of the target.

Simple Optimizations:
- Avoid O(n^2) linked list looping that checked the entire list before
adding elements (NULL values in the source array to prevent dupes).
- Re-use vert & edge lookup tables instead of allocating new ones.

Docs: rename var and comment how it's used

switch_from_camera wasn't right since it was used for auto-perspective.

Increase max/min frame range to over a million

For some specific pipelines (e.g., holographic rendering) you can easily
need over a million frames (1k * 1k view angles).

It seems a corner case, but there is no real reason not to allow users
doing that.

That said we do loose subframe precision in the highest frame range. Which can
affect motionblur. The current maximum sub-frame precision we have is 16.
While the previous limit of 500k frames has a precision of 32.

Thanks to Campbell Barton for the help here.

Fix T52472: VSE Audio Volume not set immediately

Audio mixing is done with volume interpolation. A new handle started at
volume 1, now starting at volume 0 for a smooth fade in.

Fix T52588: Shape key value driver variables of duplicated object sets refer to old objects.
