UI: move top-bar into the spaces header

Currently this is only in the 3D viewport however all spaces
that use the tool-system will have this region added.

D4680 by @brecht with own updates.

Armature: remove remains of the object-level deformation data cache.

Now that B-Bone shape data is kept in bPoseChannel_Runtime, the
armature level cache only holds one quaternion value per bone.
It can also be moved to runtime, and the structure removed.

This has an additional effect that, as far as I can tell, now
the Armature modifier can run as soon as all of the bones it
actually needs are done, thus making T59848 a purely depsgraph
level problem.

UI: Revert fix T37463: Y-clamp for header-only spaces

This reverts 91d8519c4782 since I can't redo the reported error
which was in the old header-only info space.

PyTests: do not load addons in load_py_modules test.

It makes no sense to load add-ons here, we already do that (in a more
complete way) in load_addons test, this is only adding overhead and
doubling code to maintain).

Also do not try to load-as-modules add-ons that are not 2.8-ready, and
some other misc fix.

load_py_modules test should be passing again now.

Thanks to @sergey who did part of the work here as well.

Fix T63332: backup and restore bPoseChannel_Runtime data during COW.

Images: support packing edited images as OpenEXR or PNG.

This way float and multilayer images can now be packed without data loss. This
removes the as_png option and always uses the appropriate file format depending
on the image contents.

Cleanup: unused region init functions

UI: collapse 3D view collections visibility panel by default.

OpenEXR: add support for writing EXR files to memory.

Cleanup: deduplicate single/multiview image packing code.

Cleanup: move image saving code to blenkernel.

Cleanup: make image saving code reusable outside operator.

Cleanup: deduplicate image user initialization, make consistent.

Merge branch 'master' into greasepencil-object

GPencil: Add option to mix color with texture

This was already supported in Fill, but not in Strokes. This adds more artistic options when use textured strokes.

Cleanup: add trailing commas to avoid right shift

PyTests: do not try to load non-2.8-ready add-ons.

GPencil: Fix Drawing Path follow error while drawing

The strokes was aligned to drawing path only when the stroke was completed. Now, the stroke is aligned while drawing too.

GPencil: Initialize variable to remove console warning
