Fix T65809: Blender crash while using the Normal's "merge" option in edit mode.

Merge code will generate temp normal editing data for affected loops,
but since it will later (by setting some edges/faces to smooth) alter
and extend affected clnor spaces, it will also need temp normal editing
data for some other loops around those vertices...

Using those clnor editing data in that code is a bit of an abuse, but on
the other hand that struct stores exactly what we need.

So simply added an option to generate that editing data for all clnors
of affected vertices.

Convert Embree's internal data to Blender BVH4

Drivers: shorten the security restriction warning.

A longer string is truncated in the popover, which can't be resized.

Drivers: fix Variable Copy & Paste in the edit popover.

Without these buttons the functionality of the popover is
incomplete compared to the Graph Editor panel. To support
this the operators have to read the active F-Curve from
the context, instead of directly scanning animation data.

Expanding the context would also help Python operators.

Merge branch 'master' into soc-2019-outliner

Outliner: Add modifier keys to box select

Adds shift for add and ctrl for subtract, matching the 3D view
default keymap.

Fix: File browser icons intersecting in thumbnail view

The new icons were colliding in the corners. This moves the ID type icon inside the file box to avoid this clash.

Fix Cmake Error.

`LAST_EXT` only works in versions 3.14 or greater.

Cmake: Add `WINDOWS_USE_VISUAL_STUDIO_SOURCE_FOLDERS` option

This allows grouping files in a filter corresponding to the source files name.

Differential Revision: https://developer.blender.org/D5077

Cmake: rename `WINDOWS_USE_VISUAL_STUDIO_FOLDERS` option to `WINDOWS_USE_VISUAL_STUDIO_PROJECT_FOLDERS`.

QtCreator/Visual Studio: Group glsl files in Shaders group.

Fix: Clicking in empty area in Node Editor was no longer deselecting all.

There was a missing keymap property on the select operator for both the default and Industry Compatible keymap

fix attempt for binding to particles

Windows: Clear PYTHONPATH variable in various debugging batch files.

The PYTHONPATH environment variable sometimes causes issues,
clearing it in the helper batch files is easier than talking
every user individually though the process of removing it
to see if it resolves the issue they are having.

Outliner: Show enable/disable button for constraints

This adds the restriction icon for constraints in the outliner so
they can be enabled/disabled similar to modifiers.

It also moves the icon definition to RNA from the UI template for
the constraints in the properties editor.

WM: Remove Cmd-LMB for RMB emulation for apple

The default apple keymap now uses Cmd as Ctrl,
so the key isn't free to emulate RMB.

Cleanup: spelling
