Merge branch 'master' into soc-2020-outliner

Better performance when there are clusters of coplanar triangles.

UI Code Quality: Use LISTBASE_FOREACH in interface directory

I only skipped a few loops in the monstrous ui_handle_menu_event
function. Also, I only changed variable names where necessary to
prevent redeclarations.

BLI Listbase: Add iterator macro that increments an index

Quiet const warning

Cleanup: Remove broken context menu mode toggle code

The outliner context menu had an operator to enter/exit modes, but it
only showed when the objects were in modes. Additionally, I'm not
certain how much it was used since it has been broken for a long time
and no one has reported it.

Entering modes through the context menu could be a nice feature, but I
think it would be an easier problem to solve after a context menu
refactor.

Cleanup: Outliner mode toggle warnings

Remove warnings from unused parameters.

Cleanup: Remove unused outliner select code

No functional changes.

Cleanup: Remove unused tree sort code

No functional changes

Cleanup: GPUState: Remove GPU_state_init()

GPUState: Use GPU_viewport to set viewport state in GPU_framebuffer

also fix a small issue in GPU_texture_clear.

GPUState: Port default state to StateManager constructor

Cleanup: DRW: Use GPUState instead of raw opengl calls

Should not break anything! Huh!

GPUState: Only apply state before drawing

Cleanup: GPUState: Remove stack from the state manager and rename it

GPUState: Remove gpuPushAttr/gpuPopAttr

And use manual save/restore mechanism.

The stack method is not used so much to be considered useful.

GPUState: Make use of GPUStateStack class

This isolate most GL calls to the GL backend. Still a few remains.

Cleanup: GPUState: remove double GPU_blend calls
