Fix T52324: Metaball disappears when deleting first metaball object.

Lost specific MBall 'need update' case here in last year's refactor.

While technically not a regression, nice to have in 2.79.

Fix width estimation for empty layouts in pie menus

Fix broken API doc generation: Partially revert rBa372638a76e0

Making those arrays static remove them from exported symbols, which
breaks API doc generation script.

To be backported to 2.79 branch.

Fix fixed width box layouts

Regression, to be backported in 2.79.

Fix T52250: Glitch in UI in the addon panel regression

Fix T52280: The Image node in Compositing can't read Z buffer of openEXR in 2.79

As part of the fix for T51587, I removed the Depth output for non-Multilayer
images since it seemed weird that PNGs etc. that don't have a Z pass still get
a socket for it.
However, I forgot about non-multilayer EXRs, which are a special case that can
actually have a Z pass.

Therefore, this commit brings back the Depth output for non-multilayer images
just like it was in 2.78.

Fix T52260: Blender 2.79 Objects made duplicates real still refer armature proxy.

New code was handling correctly ID's internal references to self, but
not references between 'made real' different objects...

Regression, to be backported in 2.79.

Fix T52263: Crash When Splitting and Merging Areas with Header Text Set.

Not a regression, but safe enough to be included in 2.79.

2.79 release: point submodules to correct branches and versions.
