Removing Blender Game Engine from Blender 2.8

Folders removed entirely:
* //extern/recastnavigation
* //intern/decklink
* //intern/moto
* //source/blender/editors/space_logic
* //source/blenderplayer
* //source/gameengine

This includes DNA data and any reference to the BGE code in Blender itself.
We are bumping the subversion.

Pending tasks:
* Tile/clamp code in image editor draw code.
* Viewport drawing code (so much of this will go away because of BI removal
that we can wait until then to remove this.

Disable GAME ENGINE from the build options

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

Particles: Hair: Make hair selectable in the 3D view.

Interface: Show properties values from evaluated datablocks

This is a way to deal with animated properties in evaluated version
off datablock. Previously, running blender with copy-on-write enabled
will show original values. Now we can see proper properties, while
typing values in still goes to the original datablock.

Thanks Brecht for the review!

Object Mode: Fix wrong wire color on non-meshes objects.

Object Mode: Cleanup uneeded texture attachment.

Merge branch 'blender2.8' into blender2.8-workbench

Workbench: Switching Draw engines based on draw mode

UI: Fix T54691: Vector icon vs Widget base ordering.

It was making keyframe marker and bone theme color icon disappear under
their button.

Eevee: Render: Fix assert with framebuffer not being bound before read.

Eevee: Fix AA in render mode.

Was due to wrong framebuffer being read because of wrong comparisson caused
by b9ec7a92725e1567c12475a9eb59191edca1dc32

Workbench: Draw modes

Depsgraph: Allow querying NULL IDs for evaluated version

Saves us from extra checks for NULL pointers when using datablocks for read.

DRW: Fix lightprobe objects outlines.

GPU: Add GPU_SHADER_INSTANCE_VARIYING_ID_VARIYING_SIZE.

Will be used for probe outline id drawing.

DRW: Add DRW_UNIFORM_INT_COPY.

This allow to use int uniforms that are not references. Convenient for ids.

Depsgraph: Fix unwanted node tree copy-over

Was caused by two things from the past:

- Tagging would set id->recalc to COW update flag.
This one is to be ignored.

- Particle tagging will use psys recalc flags on id->recalc,
but we only need to use flags from particles. Otherwise
it will be some collisions in bit masks.

bpy consistency fix handler_add(handle)

This doesn't change the API, so it doesn't affect any script.
However it give more consistent error messages.
