Cleanup: Define alpha field.

Fix inconsistent usercount handling of MaterialGPencilStyle.ima/.sima

Readfile was treating them as refcounted, RNA as user-one, and libquery
as not refcounted at all!

Full usercount makes more sense here, those images are used as 'real'
data for GP materials, not as temp setting of a brush!

Cleanup: Fix unused parameter warning.

Cleanup: fix error w/ const arg

Cleanup: Remove duplicate parameter (cont.)

Cleanup: Remove duplicate parameter

Modifier copy function uses const now.

Remove the simple hair guide generator, can test through the API now.

Hard-coded support for arrays, color works

Collections: more work on unification with groups

* Removes the special exceptions for group reference counting. Unlinked
collections now get a faker user. The weak point here is that unlinked
collections retain their objects even if they are removed from the scene.
For some cases that's good, for tag-like collections that's not ideal.
We can investigate how that make those cases work better later.

* Depsgraph view layer evaluation was fixed to work with copy-on-write, and
the code was simplified in the process.

* Various bugfixes related to static overrides, linking and outliner.

GSoC 2018: port Lukas Stockner's hair patch

Still missing:
- some SSE ops which he disabled (I don't know why, so I didn't add
that)
- in svm_tex_coord, he invalidated NODE_TEXCO_WINDOW initialization (I
don't know why again)
- no change of util_color.h ops
- no change of nodeitems_builtin.py (XCode didn't find it in the
project)

Ref T54796

Merge Object cache allocate and add functions

As both functions are called always together, it's better to have in one only.

RNA: Replace material api

Remove DNADEPRECATED Scene->gpd from library_query.c

Deprecated DNA shall only be used in readfile?versionning code...

Add missing Object parent pointer from bGPLayer to library_query.
