Cleanup: Remove deprecated toolsettings->gpencil_src field

This was used to determine whether Grease Pencil data was stored
on the Scene level or per Object. It isn't actually used anywhere
in 2.8 now, with the GP Objects / Annotations. Removing now
to make space for storing the toolsettings for the annotation tools.

Multithread OK.

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

move line layer and delete line layer component ok.

Line selection from object and collection is ok, material pending.

GP UI: Make the "Grease Pencil Paper" panel/options part of the Overlays popover

This is a special feature only used during Draw Mode, and functionally
acts like an overlay. Some cleanups/tweaks to this are needed still,
but it's good to get it out of the way.

Cleanup: Variable Naming

Fix for py errors in console, caused by bad poll callback for the "Animation" panel

Revert "Add annotation layer with the right name"

This reverts commit 7931a1357a0f93ac0d7b8e6a564faa0b735a96ff.

GP Object: Don't show Add/Unlink datablock buttons for GP datablock ID selector

These buttons are not shown for any other object type,
so these shouldn't be shown for Grease Pencil objects.

Fix: Ensure correct names when using the "New Layer" operator for GP Object and Annotations

This replaces what 7931a1357a0f93ac0d7b8e6a564faa0b735a96ff
tried to do. We may still need to make these separate operators
to simplify things even further.

Remove Animdata update for Palettes

This datablock is not animatable.

Fix parameter type after merge
