Color management tweaks

First round of taking care of code review remarks from sergey

Address review points:

* Deduplicate panel for texture paint brushes
* Use compare_len_v3v3_squared for color comparison in 2d fill tool
* NULL check when adding texture.

Refresh texture paint caches of materials on changing render engine.

This is not perfect yet - it would help a lot if we could restore the
node mode of a material when changing the render engine too, but this
is maybe for later.

Also did some naming cleanups - we have texture paint slots now for
materials, not images.

Fix dm material array generation after last corrections.

Misc minor changes
- add WM_drag_free_list()
- use len_manhattan_v2v2 to compare point distance
- avoid calling BKE_scene_use_new_shading_nodes in a loop

Correct DM_DRAW_USE_ACTIVE_UV, was defined as (DM_DRAW_USE_COLORS | DM_DRAW_ALWAYS_SMOOTH)

also cleanup headers in paint_curve.c

Sync with master (remove diff noise)
also add WM_DRAG_NOP to show wmDragFlags use

Code cleanup: style and float<>double promotion

Spelling
