Merge branch 'blender2.8' into greasepencil-object

# Todo's / Need Further Review:
# - material.c - "man->gpcolor = NULL" (commented out for now)
# - rna_material.c - "rna_Material_update()" - Should GP material settings use their own update?
# - GP Modifiers typedefines need updating for the new struct layout
# - Merge conflicts in properties_gp_common.py - Mostly due to panels being removed in GP branch
# - GP Panels in 3D View (toolbar/topbar fixes postponed till after branch merge)
# - GP "Paper" Option/Settings (should become overlay? Design work needed)

Cleanup: Material Buttons for GP

* Don't collapse panels by default
* Cleanup old code/names/etc.

GP Properties: Separate onion skinning for datablock + per-layer override into separate panels

The panel layouts are still a mess, but at least there's less code duplication
and weirdness now, with everything taking advantage of more conventions here.

Remove dirty cache calls from kernel

The function BKE_gpencil_batch_cache_dirty() must be called only from operators or RNA.

Besides, the calls removed were redundant.

GPencil Editors API: Added utility function to be called to get Copy-on-Write evaluated copies of data

* Use ED_gpencil_get_active() for writing settings back to the original datablock
(existing callback used in most operators now)

* Use ED_gpencil_get_active_evaluated() for getting the COW-evaluated geometry
(i.e. with modifiers, etc.) applied. i.e.,
``` const bGPdata *gpd_eval = ED_gpencil_get_active_evaluated(C); ```

Code Cleanup: Clearly label which parameters are used for input/output

Cleanup: Fix indentation

Cleanup: Fix some more warnings

NOTE: For rna_GPencil_stroke_new(), the problems aren't entirely eliminated yet.
Specifically, the colorname arg is now unused - it was used in the past to
specify what color the new strokes should have.

Cleanup: Remove unused var

Revert to use again BKE_gpencil_batch_cache_dirty()

These functions were changed by error when replace dirty management by depsgraph.

The depsgraph is only valid for operators and the files included in this commit must call the function directly and don't use depsgraph tag.

Back BKE_gpencil_batch_cache_dirty function

This function was removed by error in previous commit.

Cleanup: Add new line at EOF

Remove BKE_gpencil_batch_cache_dirty()

This remove the function because is not used.

Replace DRW_gpencil_batch_cache_dirty() with DEG_id_tag_update

Cleanup. Rename material variable to "ma"

The old name "mat" could be confused with matrix.

WIP depsgraph fixes for GP and depsgraph

Still not working yet - somehow the updates aren't getting flushed yet
(perhaps COW related)

Cleanup: Indentation

Add default brush material to object materials

When draw using a brush that uses a default material, the material must be added to the object material slots if this material was not before.

Rename Grease Pencil Array Modifier to Instance Modifier

The new name is more clear and does not create confusion with 3D objects array modifier.

Fix error drawing with no object active
