Cycles: Use falltrhough attribute to help catching missing break statements

Proper fix for crash loading old files with compositor

Now we keep all links around, even for sockets which were
implicitly renamed. And also ensuring new sockets have proper
storage.

Remove TexFace, per-face images

TexFace complicates the now more popular shading pipeline by having
per-face images, see: T51382 for details.

To keep the ability to select a per-material edit-image
(used with UV-mapping workflow), the material now stores an image
which will be set when changing images in edit-mode.

This is used as a bake-target when not using Cycles too.

Revert "Fix crash opening really old files with compositor"

This commit broke compatibility with newer files: due to rename
of Speed to Vector the links got lost.

This reverts commit 0e46da76b70a42bab2268942cba0e0d3e4ba47e8.

Cleanup: minor de-duplicate from last commit

Fix T51561: Normal maps fail w/ quad + eevee

Generalize derived-mesh tangent calculation so
it can be used by Batch cache creation too.

Fix possible invalid normal use w/ tangent calc

Was using MFace normals, not MPoly

Merge branch 'master' into blender2.8

Alembic: Export mesh as mesh, even when it has no vertices.

This makes it possible to have an animated / procedurally generated mesh
that starts empty and obtains data in later frames.

Fixes the export of an empty mesh with an Ocean Modifier, as described in
issue T51351.

Alembic export: consider mesh with animation data as "animated"

This allows you to put any kind of animation data on the mesh, and its
shape will be exported on each timekey. Note that this timekey is unrelated
to the animation data (so we don't export on each keyframe, for example).

A practical example is the addition of an animated custom property to
trigger the export of animated mesh data. The mesh data can then be created
from any source, like Python scripts.

Not only is this useful in itself, it also provides a workaround for one
of the two issues described in T51351.

Alembic export: write Blender version to Alembic file

This is written in a custom metadata key, so it isn't shown by utilities
like abcecho or abcls. However, it's still something that's useful to
have available.

CMake: document that WITH_FFTW3 is also used for the ocean sim.

Fix T51586: Regression: Alembic containing animated curves / hair no longer working

Also fixed the same type of error when reading points.

Fix T51589: Principled Subsurface Scattering, wrong shadow color

Apply mix of subsurface and base color (wrt subsurface) for rays that
have transmitted the surface.

Move empty image drawing into its own pass

Cleanup: bmesh var naming

Fix leak in particle velocity global ramp

DwM: avoid indirect edit-mesh conversion

Storing edit-mesh data as indices for passing
only to get back edit-mesh data.

This also complicated checks for real edges in tessellation tris.

Simpler to pass data directly.

Optimize particle primitive shader

Temp fix for vertex format with batch instancing

This prevents memory alignment from being screwed up when attributes are
optimized out in shader.
