BMesh Inset: remove hack to store coords in normals

GHash, Edgehash: add lookup_default() funcs.

Returns a fallback argument when the key isn't found.

Basic support for UNC paths on Windows

Differential Revision: https://developer.blender.org/D298

Allows users on Windows to enter UNC paths in the filebrowser and to link to .blend files on a UNC path. Functionality is limited still, we can't browse the network yet and have no support to check user rights so far.

What works:
- enter an UNC path in the file browser manually or via copy/paste
- navigation within the UNC share subfolders
- link to a file on a UNC share

What does not (yet) work:
- browse the network for computers and shares
- browse to a folder that requires entering user credentials

Fix GLSL after 7765b73f6d20 (Transparent Depth).

Code cleanup: remove old closure sampling code Cycles.

This was the original code to get things working on old GPUs, but now it is no
longer in use and various features in fact depend on this to work correctly to
the point that enabling this code is too buggy to be useful.

Cycles: add Transparent Depth output to Light Path node.

This can for example be useful if you want to manually terminate the path at
some point and use a color other than black.

Code cleanup: view2d api naming

Libmv: optimization of PearsonProductMomentCorrelation

Pass the arrays by reference rather than by value,
should give some percent of speedup.

Also don't pass the dimensions to the function but
get them from the images themselves.

Hopefully this will give some %% of tracker speedup.

Fix player build.

View2d: check UI_view2d_view_to_region_clip succeeds before using the result

View2d: API Cleanup for view<->region conversion

View2D had some inconsistencies making it error prone in some cases.

- Inconstant checking for NULL x/y args.
Disallow NULL args for x/y destination pointers, instead add:
- UI_view2d_region_to_view_x/y
- UI_view2d_view_to_region_x/y

- '_no_clip' suffix wasn't always used for non-clipping conversion,
switch it around and use a '_clip' suffix for all funcs that clip.

- UI_view2d_text_cache_add now clips before adding cache.

- '_clip' funcs return a bool to quickly check if its in the view.

- add conversion for rectangles, since this is a common task:
- UI_view2d_view_to_region_rcti
- UI_view2d_region_to_view_rctf

Fix T39818: Strips from file with long filename broke auto-naming - animation can't be apply on it.

Fix for UI_view2d_to_region_float (was ignoring x,y args)

use this for grease pencil stroke conversion to avoid float->int->float conversion.
