Icons for Grease Pencil/Annotation tools

These were in the icon_geom.blend file in SVN (lib/resources),
but needed to be manually added to the Export group for this to
work.

They are needed for use for use with the annotation tools.

NOTE: There are currently problems running the icon generation
scripts in the gp-object branch due to some file loading pointer
remapping problems there causing segfaults when running the script.
Thus, I generated these icons using the 2.8 branch, then cherry-picked
that commit over to this branch.

Fixes for incorrect version patching code introduced in b6776304e76a

* newlibadr() shouldn't be called from direct_link_* functions
Besides, the pointers in question get corrected in
lib_link_material() already

* Added expand_doit() calls for the sima and ima pointers.
Following what's done for tex->ima, these also get expand_doit() calls,
since they increase the usercount of images when used.

Cleanup: Remove the obsolete "ts->gp_brushes" field

This isn't used or accessed from anywhere anymore, so time to remove it

Fix: Crash when erasing annotation strokes

The code was assuming that dvert data always exists on strokes
(it shouldn't, if we're doing everything correctly!), which
caused crashes when erasing annotation strokes (which definitely
don't have this data).

TODO:
Check that the rest of the code doesn't make similar assumptions!

Cleanup: Remove 2D Editor support from gpencil_paint.c

The "GPENCIL_OT_draw" operator pretty much didn't support non-3D
views already (at least not without crashing). Now that we've got
a separate/dedicated operator for Annotation support (GPENCIL_OT_annotate),
we can remove the old 2D Editor support here.

Cleanup: Remove "Scene->gp_object"

This was from an earlier design for supporting Annotations,
where in the 3D view, we would have only had GP Objects.
Now that we've moved away from that idea, and are back to
having a separate "Annotations" system, this concept can
be removed from the code again.

Annotations: WIP first steps towards toolbar support

This adds a toolbar entry for activating the annotations tools
as active tools. Many things are WIP still (e.g. tool settings
are yet to come, as the necessary props aren't defined in DNA/RNA yet).

Todo's:
* Icons are missing. The necessary icons *do* exist right now
in the icon_geom.blend file, but I can't get them to export/generate
.dat files that we can use in the UI here. That said, the placeholder
names (from that file) are now used.

* Key mappings need work/testing. They seem to work well enough as-is
already though

* Tool settings (in topbar) are not implemented yet. Coming soon
(aka tomorrow, after I get some sleep)

* Non-3D view toolbar support

Cleanup: Remove deprecated toolsettings->gpencil_src field

This was used to determine whether Grease Pencil data was stored
on the Scene level or per Object. It isn't actually used anywhere
in 2.8 now, with the GP Objects / Annotations. Removing now
to make space for storing the toolsettings for the annotation tools.

GP UI: Make the "Grease Pencil Paper" panel/options part of the Overlays popover

This is a special feature only used during Draw Mode, and functionally
acts like an overlay. Some cleanups/tweaks to this are needed still,
but it's good to get it out of the way.

Cleanup: Variable Naming
