Merge branch 'master' into blender2.8

Cleanup: Use BLI_strncpy

It has behavior which we expect, and silences strict compiler warning.

Fix T55278: Lightmap Pack > New Image broken when active object is None

thanx bblanimation (Christopher Gearhart) for spotting the issue and
providing the fix!

path_util: avoid overflow w/ strtoll use

Also style cleanup.

3D View: move screen overlays to the top

- Frame & object name now top left.
- Axis now top right (when view navigation disabled).

This is needed so we can use the lower area for redo popup, see T55386.

WIP: Add driver eyedropper operator button beside the "add input" button

This doesn't work currently. Needs more investigation why.

Drivers UI: Introduce more whitespace, to make the sections clearer

Support UDIMs in Image Space operators

Merge branch 'master' into blender2.8

Cleanup: Remove the "all" parameter from "ANIM_OT_driver_button_edit"

This won't ever be used for this operator, as the "edit" operator should
only ever be used for dealign with a single driver - the one under the
cursor.

Overlays: Reserve space for a "Onion Skins" overlay

While we probably won't be getting a general purpose "Onion Skinning"
overlay anytime soon for meshes, etc. (at least not before the
depsgraph stabilises, and we also get geometry caching working),
for the Grease Pencil integration at least, it makes sense to move
GP objects to using a more general/future-proof solution, instead
of continuing to use a special/dedicated button in the header.

Currently the UI part of this is commented out. Also, the GP branch
doesn't need to move to this pre-merge. But, since 2.8 changes move
fast, it's better to reserve the space now to have it next to motionpaths,
than introduce it later.

Drivers UI: Don't show the Copy/Paste driver dvars buttons in the popovers

The copy/paste driver variables buttons currently only work when used in the
Graph Editor as they rely on being able to have the "active F-Curve" context
info that's only present in the Graph Editor (in Drivers Editor mode).
Instead of having them constantly greyed out in the popover, it's easier
to just hide them for now. Besides, this is probably more of an "advanced"
feature that we don't need to expose in the simple UI.

Fix T55349: crash adding paint slot when object is on hidden layer

use better poll and get ob with 'ED_object_active_context' (instead of
'CTX_data_active_object')
