Correct error from texface removal

Missed stencil layer

Always using full shading for eevee + sculpt mode

Also disable for dyntopo & multires since its currently not supported.

Merge branch 'master' into blender2.8

Revert T44320: UV island overlap considered linked

In the reported example it seemed reasonable to apply this change.
But it causes a much more common case (selecting projections)
to be split into 2x islands.

Resolves T50970

Fix T51100: Vertex pick fails after extrude

Snap System: remove unused function

DwM: Option to use final material over mode shading

Support using full material shading in sculpt & paint modes mode.

Access 'Full Shading' from the display panel when in paint modes.

Gawain: add GWN_vertbuf_clear

Needed to clear the buffer without freeing.

BMesh: move safe loop-normal-calc to own function

This makes sense when we want to avoid float precision error
for near co-linear edges. OTOH, this is an arbitrary decision,
so keep functions separate.

Depsgraph: Remove meaningless comment

We are already on the new depsgraph only for quite some time now.

Cycles: Enable SSS from Principled BSDF only when actually in use

This gives speed up for the split kernel in scenes using the principled BSDF
but without subsurface scattering.

Cleanup: unused vars

Cycles: Fix comparison in principled BSDF

Could have lead to black pixels.

Fix T52027: OSL getattribute() crash, when optimizer calls it before rendering.

Fix [T51595]: Snap to edge does not work with high zoom level

That problem occurs because of the imprecision of `short int` (16 bits).
The 3d coordinates are converted to 2d, and when they are off the screen, their values can exceed 32767! (max short int value)

One quick solution is to use float instead of short

The snap code is actually a little tricky. I want to make some arithmetic simplifications in it
