GWN: Port to GPU module: Move files to GPU

This does not include all the struct and type renaming. Only files were
renamed.

gwn_batch.c/h was fusioned with GPU_batch.c/h
gwn_immediate.c/h was fusioned with GPU_immediate.c/h
gwn_imm_util.c/h was fusioned with GPU_immediate_util.c/h

GWN: Port to GPU module: codestyle & licence

Merge remote-tracking branch 'origin/master' into blender2.8

make.bat: remove msvc2013 support.

Render: add "OpenGL" render engine.

This is intended for quick renders for previsualization, animation previews
or sequencer previews. It provides the same settings as found in the 3D view
Shading popover in solid display mode, but in the scene render properties.

The "Workbench" engine was removed, and this name no longer appears in the
user interface, it's purely an internal name. We might come up with a better
name for this OpenGL engine still, but it's good to be consistent with the
OpenGL Render operator name since this has a similar purpose.

Fix weld incoherent normals with weld operation

Cleanup: moving shading type into View3DShading.

So all shading settings are in this struct and can be reused in the OpenGL
render engine.

UI: move specular light settings to Lights tab in user preferences.

Fix Python error removing studio lights in user preferences.

Fix inconsistent shade smooth naming in object and edit mode.

Merge branch 'master' into blender2.8

Fix T56003: Opening image files as movies in VSE crashes.

metadata loading code was assuming all videos in Blender were from
FFMPEG... added empty place-holders for other types too, we probably
could load some metadata from pictures or AVI files too!

World: Added 'Viewport Display' panel

The Properties->World tab had no Viewport Display panel. The world color
itself was hidden when the 'use_node_tree' was enabled.

Also renamed the World.horizon_color to World.color as it has nothing to
do with the color of the horizon (old BI feature)

UI: Single-column and flow layout for Scene properties

See D3532

UI: Minor fixes to separators on menus

Closes D3547

Object Mode: Add back object bound display

UI: Lamp -> Light for the object type visibility operators


Spotted in a live stream by Emilton Mendoza, thanks!

Fix (IRC-reported) wrong usercount handling of deprecated IPO datablocks.

versionning code would unref those twice... Reported by @�ergey on IRC, thanks!

Eevee: Add debug visual for Cascaded Shadow Maps

DRWDebug: Add new debug functions for spheres and matrices.
