Compositor: Full-frame base system

This patch adds the base code needed to make the full-frame system work for both current tiled/per-pixel implementation of operations and full-frame.

Two execution models:
- Tiled: Current implementation. Renders execution groups in tiles from outputs to input. Not all operations are buffered. Runs the tiled/per-pixel implementation.
- FullFrame: All operations are buffered. Fully renders operations from inputs to outputs. Runs full-frame implementation of operations if available otherwise the current tiled/per-pixel. Creates output buffers on first read and free them as soon as all its readers have finished, reducing peak memory usage of complex/long trees. Operations are multi-threaded but do not run in parallel as Tiled (will be done in another patch).

This should allow us to convert operations to full-frame in small steps with the system already working and solve the problem of high memory usage.

FullFrame breaking changes respect Tiled system, mainly:
- Translate, Rotate, Scale, and Transform take effect immediately instead of next buffered operation.
- Any sampling is always done over inputs instead of last buffered operation.

Cleanup: Split draw_cache_extract_mesh into multiple files.

draw_cache_extract_mesh for task scheduling. Will be refactored to draw_cache_extract_mesh_scheduling later on after migrating to CPP.

draw_cache_extract_mesh_render_data extraction of mesh render data from edit mesh/mesh into a more generic structure.

draw_cache_extract_mesh_extractors containing all the extractors. This will be split up further into a single file per extractor.

Cleanup: split face tessellation into inline functions

Prepare for multiple code-paths that recalculate tessellation.

Cleanup: split bmesh tessellation into it's own file

Prepare for further refactoring for these functions.

Cleanup: remove disabled face tessellation logic

This was kept since these blocks are easier to follow.
Remove as the overall result wasn't so readable
(especially with nested ifdef's).

Replace disabled code with comment on the indices used for quads/tris.

BMesh: remove checks for tessellating 2 sided faces

2 sided faces aren't supported and will cause problems in many areas
of Blender's code.

Removing (implied) support for faces with fewer than 3 sides
means the total number of triangles is known ahead of time.

This simplifies adding support for multi-threading and partial updates
to an existing tessellation - as the face and loop indices can be used
to access the range of triangles associated with a face.

Also correct outdated comments.

Cleanup: correct sculpt quat argument size

GPU: add 2D projection function

When projecting into screen space Z value isn't always needed.
Add 2D projection functions, renaming them to avoid accidents
happening again.

- Add GPU_matrix_project_2fv
- Add ED_view3d_project_v2
- Rename ED_view3d_project to ED_view3d_project_v3
- Use the 2D versions of these functions when the Z value isn't used.

Docs: Limit the OCIO env vars that we document

Brecht mentioned that these are a bit obscure and don't make much sense
to override these.

Speedup exact boolean by avoiding some mallocs and frees.

This is from patch D11432 from Erik Abrahamsson. He found that
in some mpq3 functions called frequently from loops, passing in
buffers for termporary mpq3 values can save substantial time.
On my machine, his example in that patch went from 9.48s to 7.50s
for the boolean part of the calculation. On his machine, a running
time went from 17s to 10.3s.

Cleanup: Replace fseek() calls with BLI_fseek()

The fseek() function on Windows only accepts a 32-bit long offset
argument. Because of this we have our own version, BLI_fseek(), which
will use 64-bit _fseeki64() on Windows. This patch just replaces some
fseek() calls with BLI_fseek().
