GP Branch Version Patching - Use palette slots instead of creating palettes directly

Revert whitespace edits in interface_utils.c

These appear to be accidental, and are unrelated to the purpose of this branch.

Fix: Palettes were getting freed before GPencil datablocks on exit

First test to implement FXAA

Merge branch 'blender2.8' into greasepencil-object

Fix compile error after merge

(Also added convenience API to make it easier to add new palettes to GP
datablock without having to worry about manually fixing usercount)

Fix: When adding 2D Monkey, the Palette got too many users assigned

Added missing support for duplicating Palette Slots when copying GP data

For now, it will only increment the usercount of the referenced palettes.

Code Cleanup / TODO Notes (re- reuse of palettes when validating)

Code Cleanup / Compile Fix

Further cleanups for the 2D monkey primitive - this time, to move
all the data arrays out of the single massive function, and out to file level.

Hopefully this solves the compile problems with GCC.

If nothing else, the file now compiles much faster here on MSVC
(i.e. previously, it was taking ~10-20 seconds to compile)

Tweak behaviour of adding a new GP Palette (to match other parts of Blender)

When creating a new Palette with an existing Palette assigned to a slot,
a copy of the old Palette will be created (i.e. the new copy will have all
the same colours), instead of creating a blank palette.

This makes it easier to create different versions of the same palette.

Palette Slots - Temporary verison-patching code to add slots for early 2.8 files saved without these

Palette Slots - Add operators to Add/Remove Palette Slots

* Add will create a new (empty) slot by default

* Remove will shown an error if the slot is currently still used by
any strokes. Perhaps in future, it should remap the strokes instead?

* Added icon for Palette Slots (it uses the same icon as Palettes now)

Fix: Missing undo flags for various GP operators

Code Cleanup - Remove old/non-existent operator defines
