Cycles: Fix compilation warning

Cycles: Correct logging of sued CPU intrisics

Fix T51907: New Depsgraph - Camera constraint is not evaluated properly

This is more a workaround for until we've got proper visibility flush, which
will likely happen in blender2.8 branch.

Cycles: FIx issue with -0 being considered a non-finite value

Alembic: Fix T52579: crash when replacing slightly different alembic files

Apparently with Maya in a certain configuration, it's possible to have an
Alembic object without schema in the Alembic file. This is now handled
properly, instead of crashing on a null pointer.

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.

Docs: BMesh.from_mesh behavior w/ multiple calls

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.
