Fix T56662: Autocomplete for texture slot Crash (in console).

That pointer can be NULL, RNA default string handling does not support
that. (that whole uv_layer prop is quite nasty actually, since it does
not own that string, always borrows it from some other data :((( ).

Fix T56763: Removing driver variable crashes Blender.

Rebuilding depsgraph is not enough, with COW we also need to ensure COW
copies get updated accordingly.

Had to tweak the generic update system here, since it was always passed
a NULL pointer for the callback arg, this should not change existing
behavior (besides crash fixing ;) )...

GP: Reduce factor of thickness for soft eraser

Possibly fixed shader errors, but don't know exactly what caused it.

GP: Improve SOFT eraser to affect strength and less to thickness

Cleanup: Spelling mistakes

Pointed by John Roper and Ray Molenkamp.

Multires: Use more clear naming

There are so many reshapes now, and one more is to come.
Better be explicit.

Merge remote-tracking branch 'remotes/origin/blender2.8' into soc-2018-npr

GP: Fix pressure jitter problem

The pressure was not used in jitter factor.

GP: Hide panels for eraser brushes

FIx T56758: Outliner - Select Hierarchy not working.

Reversed logical check on object's visibility...

Fix T56759: Status bar not working for multi-objects nor object mode

Cleanup, fullstops in comments

GPU: Remove residue of OpenSubdiv

Was done more like a hack on top of old drawing pipeline.
Should be re-implemented to fit new draw manager closer.

Merge branch 'master' into blender2.8

Cycles: Don't allocate Extra if BSDF allocation failed

Failed as in did not allocate due to possibly weight cutoff.
Tryign to allocated Extra storage for closure in such situation
will consfuse Cycles and cause crashes later one due to obscure
values in ShaderData.

Cleanup: move theme versioning into own function

Fix T56766: Bake Action Visual Keying Not Working.

Consequences of new requirement to use named keywords parameters for our
RNA API... Hopefully fixed all other cases in that file as well, but
guess we'll find more of those in comming weeks. :|

Cleanup: redundant assignment is later overwritten
