Outliner: Add auto scrolling during drag and drop

Pan the view when dragging elements near the borders. This uses the same
operator that scrolls the region during modifiers drag and drop.

Sculpt: Color filter fill mode

This implements a fill mode in the Color Filter tool, which fills the

Outliner/UI: Show library state icons for data-blocks in "Data API" mode

Previously it was not possible to tell appart a linked data-block from its
override copy. In fact you couldn't tell appart any data-blocks with the same
name (which is possible with linking).
Now we show the library state icon as we do for data-blocks in other display
modes.

This changes the drawing by drawing 2 circles with different intensity to
avoid any readability issues. This removes the need for Logic OP which is
implementation dependent.

Functions: provide dummy multi function

Sometimes it is convenient to be able to return a reference to some
dummy function.
