Fix T52299: X resolution of 4 causes nodes to collapse

Was caused by numeric overflow when calculating preview dimensions.
Now we try to avoid really insance preview resolutions by fitting
aspect into square.

Fix T52140: Align objects centers using origin for text

The issue was caused by operator redo which frees all object's evaluated data,
including bounding box. This bounding box can not be reconstructed properly
without full curve evaluation (need to at least convert font to nurbs, which is
not cheap already).

Fix T52573: Cycles baking artifacts

Synchronize condition for faces split between Cycles itself and baking API.

Fix T52679: Hole in bake normal

In fact, any type of baking might have caused holes in mesh.

The issue was caused by zspan_scanconvert() attempting to get order of traversal
'a-priori', which might have failed if check happens at the "tip" of span where
`zspan->span1[sn1] == zspan->span2[sn1]`.

Didn't see anything bad on making it a check when iterating over scanlines and
pick minimal span based on current scanline. It's slower, but unlikely to cause
measurable difference. Quality should stay the same unless i'm missing something.

minor fix for collision problem with mesh

Fix T53630: Effect strips not displaying Input data.
Fix T52977: Parent bone name disappeared in the UI in pose mode.

Regression caused by own rBc57636f060018. So instead of changing widget
type, just flag it as disabled.

Note that core of the issue is elsewhere though - there is absolutely no
reasons to have a search widget for pointers we cannot change nor
search! But fixing this is not really top priority, one of the many
glitches of our UI code, so think we can live with current code.

To be backported to 2.79a.

Fix T53463: Rotation numerical input shows instable behaviour.

Inverting a number in radians when user is in degrees gives rather
unexpected results. ;)

Fix T53420: Vertex Groups: The "-" button gets a hidden function

Guess 'remove all unlocked' is new-ish feature...

To be backported to 2.79a (I think).

Fix T53343: Custom Normal Data Transfer Crashes when some vertexes have no faces.

Odd nobody noticed this earlier, was obvious bug in code logic here... :/

To be backported to 2.79a.

Fix T53250: Crash when linking/appending a scene to a blend when another linked scene in this blend is currently open/active.

Inner DAG code would not check against NULL pointer, and in case of an
active linked scene, scene pointer will be NULL here, so we have to
check it ourself. ;)

Fix T53191: Python API Reference link wrong in splash screen.

Forgot to update splashscreen links when we switched API doc naming
scheme...

Fix bad 'poll' prop callback API doc.

This was added to all prop types, when it is only available for Pointer ones.

3D View: use shortest angle between quaternions

Gave incorrect smoothview speed changing between some axis and
axis locking.

Math Lib: signed versions of quaternion angle

There was no simple way to get the shortest quaternion angle.

bl_app_override: support empty UI layout items

Returning None from ui_ignore functions creates empty labels,
allows removing items without breaking layout in some cases.

Fix T53430: Cut at the strip end fails w/ endstill

WM: minor correction to user-pref writing

When saving templates had wrong return value.

Docs: clarify return value for BVH API

Fix BMesh PyAPI internal flag clearing logic

Would leave the flag set on raising an exception.
