Cycles: Implementation of object reference nodes spatial split

This commit implements object reference node spatial split making it possible
to use spatial split for top-level BVH.

The code is not in use yet because enabling spatial split on top level BVH is
not coming for free and it needs to be investigated if it's worth in terms of
improved render times.

Cycles: Make primitive split code easier for re-use by reference splitting function

Cycles: Move primitive splitting into own functions

This way it's easy to add more reference types allowed for splitting to the
BVH reference split function without making this function too much big. This
way it's possible to experiment with such features as splitting object instance
references.

So far should not be any functional changes.

Cycles: BVH statistics print was missing for spatially split BVH tree

Fix editmesh GLSL tangent drawing

The generic tangent calculation relied on CDDM arrays which aren't available in edit-mode.

Add a tangent calculation callback, which has its own implementation for editmesh data.

Fix T45884: Crash copying keyframes

BLI_str_quoted_substrN could crash if the prefix wasn't found

mathutils.BVHTree: support overlap self-intersect

Use same logic as BKE_bmbvh_overlap

BVHTree.FromBMesh() missed epsilon arg

Fix T45882: Sudden shutdown if the filebrowser is part of the area layout.

There is no guarantee in sfile's listener that FileList has already been created...

Fix T45860, missing extension in GLSL after recent own fix.

BGE: Fix T42679: Python physics environment not setted for python control script.

Cleanup: spelling/style

This commit makes it possible to select the sort mode whenever we invoke an operator.

It's needed especially for the menu entry "recover auto save" where you'd like to have the files sorted by date most of the time but it could be useful in other places too.
There should be no functional change in other areas, I just added the missing parameter (FILE_SORT_ALPHA).

Was a request from @sebastian_k at #BCon13, so at least one guy needs it ;)

Fix T45633 - Animated modifiers don't update in new depsgraph

* Resolved some todo's where FModifier paths were getting identified using the
wrong pattern.
* Added the missing animation -> modifier link. The "hacky" part here is just
to do with how we check if that link is needed; the link though should exist
in the graph.

Math Lib: Use same logic for 2d/3d functions

dist_squared_to_line_v2, dist_to_line_v2

Math Lib: minor optimization interp_weights_poly

Cleanup: spelling

Use epsilon for line-intersect collinear test

Also remove 2x vector normalize since other parts of the code already check this.

Fixes T45849

FileBrowser: Tweak display of size/time of entries.

We have no size for blenlib entries, nor do we have time for those and 'parent' entry.

Thanks to Sergey for notifying this on IRC.

outliner: tweak GPLayer color button overlap
