OpenSubdiv: Remove unused file

OpenSubdiv: Remove UV coordinates from converter

Converter only defines topology, not coordinates or (face)varying data.

OpenSubdiv: Re-work C-API integration

Main goal is to make API simpler to follow (at least ion terms what
is defined/declared where, as opposite of handful big headers which
includes all the declarations), and also avoid a big set of long and
obscure functions.

Now C-API files are split into smaller ones, following OpenSubdiv
behavior more closely, and also function pointers in structures
used a lot more, which shortens functions names,

UV integration part in GL Mesh is mainly stripped away, it needs
to be done differently. On a related topic, UV coordinates API in
converter needs to be removed as well, we do not need coordinates,
only island connectivity information there.

Additional changes:

- Varying interpolation in evaluator API are temporarily disabled,
need to extend API somewhere (probably, evaluator's API) to inform
layout information of vertex data (whether it contains varying
data, width, stride and such).

- Evaluator now can interpolate face-varying data.
Only works for adaptive refiner, since some issues in OpenSubdiv
itself.

Planned changes:

- Remove uv coordinates from TopologyConverter.
- Support evaluation of patches (as opposite to individual coordinates
as it happens currently).
- Support more flexible layout of varying and face-varying data.
It is stupid to assume varying is 3 floats and face-varying 2 floats.
- Support of second order derivatives.
- Everything else what i'm missing in this list.

Cleanup: doxy comments

Gizmo: update Python templates

Fix Cycles incorrect resize and CMYK conversion of uint16/half images.

GPU_matrix: use Blender's naming conventions

Thanks to @sergey for review

Cleanup: use variable names based on term gizmo

3D View: New view gizmo design

Simplify the default navigation gizmo.

See: T54723

Cleanup: style, doxy file

Cleanup: split GPU_batch

Split out presets and utilities for creating batches.
These functions are quite specialized and not related to typical usage.

UI: Default theme minor tweaks

Darker color for group nodes and minor adjustments

UI: Camera Display panel rename to Viewport Display

Matches all other panels with Viewport properties

UI: Use icon for Material Link

Communicates the same by giving more room to the Material datablock name

UI: Use full width for ID blocks in World, Light, Camera, Texture

Also close Preview panel for lights by default and move World custom props last

Merge branch 'master' into blender2.8

Cycles: add voronoi features and distance settings from Blender.

Features to get the 2nd, 3rd, 4th closest point instead of the closest, and
various distance metrics. No viewport/Eevee support yet.

Patch by Michel Anders, Charlie Jolly and Brecht Van Lommel.

Differential Revision: https://developer.blender.org/D3503

UI: Hide Preview panel by default on Material properties

And move Custom Properties panel last

Cleanup: use float3 SSE instead of ssef for voronoi texture.

WM: rename manipulator to gizmo in the toolbar
