Fix merge error

Merge branch 'blender2.8' into greasepencil-object

Optimize Fast Drawing memory management

Various RNA fixes (noticed while adding palette slot support)

* Added missing define for GP Object datatype in rna_Object_data_typef
* Improved a few descriptions/comments

Fixes for various problems with the linked-datablock handling code for GP features

* The new "Scene->gp_object" field was not being relinked in various places

* The "bGPDstroke->palette" relinking calls were missing the standard "id.lib" args

* "bGPDlayer->parent" should be handled in lib_link_gpencil() not direct_link_gpencil(),
It was also not handled in the expand_doit()

Code Cleanup - Some leftover cruft/reshuffling/formatting

Palette Slots - File IO and Basic RNA support

Palettes Slots - Fix incomplete DNA changes from previous commit

Merge branch 'blender2.8' into greasepencil-object

GP Palette Slots - Initial DNA structures

Start of support for GP "Palette Slots". These act like "Material Slots"
in that they allow a single GP datablock to refer to multiple Palette
datablocks, making it easier for the user to manage the set of available
palettes.

Code Cleanup - Clarifying names, comments, and shuffling fields for clarity

Code Cleanup - Move all old/deprecated bGPDpalette stuff together to be easier to remove/disable in future
