Related to T53003: tweak scene fps range.

Move restricted 'reasonable' range to ui_range, and allow wider values
for manual settings.

Fix T53003: IMB: Invalid framerate handling due to short integer overflow.

FFMPEG uses int for the numerator, while Blender uses a short. So in
cases people gave weird exotic framerate values and we cannot reduce
enough the numerator, we'd get totally weird values (even negative frame
rates sometimes!)

Now we add checks for short overflow and approximate as best as possible
in that case (error should not matter unless you have shots of at least
several hundreds of hours ;) ).

IMB: Add asserts that returned fps and fps base are strictly positives.

Forgot to add that in previous commit, also related to T53003.

Fix part of T53080: all material previews re-rendering after undo.

This reverts commit dc2617130b2e1d7d2b9892fbd7c6e7b60caafb66, which disabled
writing of previews for undo. While this uses some memory, re-rendering all
previews is very expensive, especially if for example you have lots of materials
using high-res image textures.

improved rotation calculation in bind animated mesh

fix for loading crash with dynamic fracture

forgot to copy the fracmesh, but this now might increase mem usage

Fix T53593: sculpt brush rake spacing bug after recent bugfix.

fix attempt for split shard to island crashes

customdata was incorrectly freed and corrupted the memory

added a limit / searchradius for animated mesh binding

bind operator now clears the simulation cache too

Cycles: Fix bug in user preferences with factory startup

Namely, the issue would happen when CPU device was never used before.
Issue with wrong merge conflict resolution.

forgot to include workaround for changing vertex counts

fix attempt for bind animated mesh

Blender 2.79a: Use latest dev-tools

This way release checker used by Linux release environment is corrected.

Blender 2.79a: Show both version char and rc text on splash

Blender 2.79a: Use proper version char

Blender 2.79a: Point submodules to updated hash

Task scheduler: Start with suspended pool to avoid threading overhead on push

The idea is to avoid any threading overhead when we start pushing tasks in a
loop. Similarly to how we do it from the new dependency graph. Gives couple of
percent of speedup here, but also improves scalability.

Task scheduler: Clarify why do we need an atomic add of 0

Cycles: Fix crash opening user preferences after adding extra GPU

We can not store pointers to elements of collection property in the
case we modify that collection. This is like storing pointers to
elements of array before calling realloc().

Cycles tests: Add extra image tests
