Cycles: Cleanup, indentation

MakeLocal: fix bad (missing) handling of proxy_from uglyness.

Those shall not be considered while checking whether a to-be-made-local
ID will end up fully local, or still be partially used by linked data...
Even less since we already do have special handling of proxies later.

Fixes main remaining issue found with 04_01_H.lighting.blend Agent327
file, and allows us to switch back to optimized post-processing in
make_local code.

Add a new LOOPBACK flag to libquery's callbacks.

That one tags those ugly little 'from' ID pointers (shape keys and
proxies), which point back from used to user ID, and require a lot of
special care in data-block management...

Clean up weight/vertex painting code

Now passing selection state instead of colors for the wire/face mask
overlay thing. Also added masking indication on the faces in vertex
paint.

Masks: Fix broken animation after adding primitives

Was missing mask shape initialization.

Not ideal from the CPU ticks point of view, but will work for now.

Cycles: Split kernel SSS & Volume data definitions cleanup

Cycles: Show samples progress for OpenCL split kernel

Fix Blenderplayer linking error

Cycles: Workaround for AMD GPU OpenCL compiler

Fix for SSS in BPT.

Eevee: Fix compilation issue on certain driver.

Merge branch 'master' into blender2.8

Fix empty struct errors in paint_vertex_mode.c

Fix (unreported) memleak in Warp modifier copying.

MakeLocal: switch back to secure, slightly slower final steps.

Again, Agent327's 04_01_H.lighting.blend shows some problem here, it
triggers several times the 'not used at all' assert in step 5 of secure
code, and with optimized version we lose the connection between
rigs and the main characters!

Will keep investigating on this, but for now let's try to give something
working to the studio.

MakeLocal: forcefully recalc affected armatures' poses.

This should not be needed imho, we already set POSE_RECALC flag
correctly there, but it still is missing actual update of poses in some
(complex and convoluted) cases. So at least for now, let's go with this
hack, it's not really harming anyone anyway.

Fixes crash in Agent327's 04_01_H.lighting.blend when making all local.

Add check (error message + assert) that pose is valid in armature evaluation.

Not sure how this happens, but in some cases we can evaluate
deformations of an armature which pose is not valid, at least put a
warning here to help identifying the issue quickly.

Use immediate mode for back-buffer selection

Needed so selection works with core profile.

Revert "Add red alert in UI controls for datablock pointer properties"

This reverts commit f5bc8ad4ce87165fc0648f1cd8c0ae1fb5f07281.

We agreed there needs to be a better solution for this, see comments in
rBf5bc8ad4ce87165.
