Depsgraph: Move data update tag to object->data itself

Depsgraph / Object update: Query data update flag from data itself

RNA: Query is_updated flag from object data ID's rather than from object itself

Masks: Remove unused function

It was used by old dependency graph. New one does things differently.

Comment out and tag unused bit as unused

Depsgraph / Du[plication: Remove workaround flag from ID

Animation does no longer tag IDs as updated, so flag is not
needed anymore.

Depsgraph / Animation: Rmove direct ID tagging from animation code

New dependency graph is supposed to have relation from animation node to
the node which corresponds to a property which is modified by that curve.
This means it is up to dependency graph to flush recalc flags, and no
manual control is needed in the animation code.

Merge branch 'master' into blender2.8

Fix T53550: E hotkey not working after the color-band picker commit

Related to D2886, the color-band picker was lacking a poll function.

Depsgraph: Cleanup, use less explicit checks of LIB_TAG_ID_RECALC_DATA

This is a part of ongoing work in Blender 2.8, where we need to replace

`object->id.tag & LIB_TAG_ID_RECALC_DATA`

with

`object->data->id.tag & LIB_TAG_ID_RECALC`

Should be no user measurable difference.

Fix T51461: Outliner: Problems removing multiple collections in sequence

We now select the LayerCollection at index 0 for the active ViewLayer after a
collection deletion operation.

Added some functions to query outliner tree data & get LayerCollection
by index using a similar approach as we do for SceneCollection indexing.

With warning and style cleanups by Dalai Felinto.

Depsgraph: Ensure dependency graph is allocated for evaluation context

This is something what we would need to ensure anyway, so doesn't seem
to make sense to NOT allocate depsgraph and then worry about this externally.

Steps to reproduce: add cube, change it's size in redo panel.

Found by Campbell during code review session.

RNA override: Cleanup & small refactor.

Remove unused func from public API.

Make parameters & variables naming more consistent accross the code.

Move RNAproperty validation/'conversion' (for IDProps case) to upper
level in code, this will avoid some useless re-processing.

Fix T53547: Metaballs as dupli objects are not updated with the new Depsgraph

Follow relations from old dependency graph.

Fix T53552: Unneeded particle cache reset on frame change

There shouldn't be a time dependency to cache reset operation.

Cleanup: Use mathlib funcs instead of inlined math

Cleanup: Whitespace

Cleanup: Split GP Sculpt and Weight Paint panels into separate classes

This resolves the need for the draw_header() + empty bl_label
hacks used to try and get this changing dynamically.
