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.

Fix edge-split bmesh operator giving empty result

Docs: correct descriptions

Edit Mesh: click extrude, ensure inverse matrix

Relied on this being set elsewhere which isn't assured.

Docs: add note for bmesh face_split_edgenet

Fix sculpt secondary color missing some brushes

D2841 by @uvwxyz w/ edits

Fix brush reset (missing notifier)

D2843 by @uvwxyz

Fix incorrect allocation size

makesdna/makesrna: silence output by default

No need to print status for basic & reliable operations,
build systems can output operations they run if needed,
or debug output changed in the source if developers are debugging.

Nice for ninja, so any printed text hints at a problem to fix.

Fix T53577: Rake sculpt/paint wrong on first step
