WorkSpace: use existing objects mode on select

When selecting an object which is already visible in another window
use the mode from that workspace without performing any mode switching.

Cleanup: Make function static

New Draw mode "Boxes"

This draw rectangles instead of Dots and allow new artistic effects.

Workspace: sync object-modes to other workspaces

When changing the mode of an object, apply this to all other
workspaces that share the same active object.

Also use copy the object-mode when duplicating workspaces.

Merge branch 'master' into blender2.8

Code cleanup: fix a few harmless warnings.

Code cleanup: make viewport free simpler and consistent with GPU module.

Update CUEW to latest version

Some Linux distribution have only libcuda.so.1, not libcuda.so.

Code cleanup: fix a few compiler warnings.

DRW: Fix broken particle drawing.

Was caused by GPU_SELECT_LOAD_IF_PICKSEL_LIST not iterating at all if shgroup->instance_count == 0.

Object Mode: Fix incorrect lightprobe wire color when in edit mode.

Cleanup: comment for depth picking code, const args

Note that setting `glDepthFunc` isn't important,
since 2.8 branch changes this value it might seem like an error
however it's harmless in this case - so better make note of this.

DRW: Disable depth test when drawing statistics

Cleanup: use 'uint' for GPU_select

DRW: Fix negative scale object drawing.

DRW: Refactor & Split draw_manager.c into multiple files.

Refactor include:
- Removal of DRWInterface. (was useless)
- Split DRWCallHeader into a new struct DRWCallState that will be reused in the future.
- Use BLI_link_utils for APPEND/PREPEND.
- Creation of the new DRWManager struct type. This will enable us to create more than one manager in the future.
- Removal of some dead code.

BLI_link_utils: Add BLI_LINKS_APPEND(list, link)
