Merge branch 'blender2.8' into workspaces

Fix face-map button being greyed out

Fix selecting bones

Ensure pose-mode cache exists

Files that were saved in pose-mode or selecting pose bones,
would have invalid cache.

Refactor workspace data accessing

Following Campbell's and Bastien's suggestion to avoid the
all-or-nothing approach of using private headers.
Instead of using private headers we do some trickery to mark struct
members or whole structs as private.
This way we don't have to go overkill with accessors/mutators but keep
them where it makes sense.

For now this adds a macro based on DNA_DEPRECATED, just to mark certain
struct members as workspace-private (throws 'deprecated' warning if used
outside of workspace.c -- this doesn't work on MSVC though, not sure on
Clang).

Also, this adds a macro to mark struct members as workspace and file
read/write private, not sure if this is really worth it. Just thought it
might be worth considering, since some data is really workspace internal
but needs to be exposed for file read/write.

performance improvement with convert to keyframes and new adaptive keyframe option (threshold of changes)

Merge branch 'master' into asset-engine

Initial commit on: Adaptive spacing (based on diff by LetterRip see:T50939).
First prototype to calculate spacing distance by measuring distance drawn on surface rather than drawn on screen.
The code is just a prototype, it needs a clean up and further testing.

Merge branch 'master' into id_override_static

fmap-only option now only works with active object

This may change but for now match clay/eevee.

Limit only face-map option to active-pose armature

Show only face-map now works in clay/eevee engines
