Add outliner's visualization for broken libs, and also tag lib ID itself as missing.

Add remaning 'init' callbacks for needed ID types.

Note all this remains a bit theoretical, some cases (ID types) are a bit delicate to handle here.7
Time and tests will say if it's OK as is.

Add some checks in BKE_xxx_init() that data is really NULLified.

Needed, since trying to (re)init data already set could lead to many issues,
and handling this is not in the scope of this function.

Note that definition of BLI_memcmp_null stuff is rather bad currently, no good idea where to place this. :|

Handling missing libs: changed idea, now adding 'real' empty data.

Just having 'NULL' data as placeholder is not really possible, too much places
to check against that.

WIP commit, still much to be done!

See T43351 for details.

Differential Revision: https://developer.blender.org/D1394

Very first step to handle missing libs/datablocks when reading a file.

Idea is, instead of ignoring completely missing linked datablocks, to
create void placeholders for them.

That way, you can work on your file, save it, and find again your missing data once
lib becomes available again.

Plans are also to be able to locate missing libs and reload them at runtime.

To support all that, we must be able to make Blender survive those missing data
(i.e. empty datablocks) all over the place. This commit contains some early work
in that direction, but this will need much much more work!

Icons: Add new 'library_data_broken' one.

Revert "Port UV display to new design. As plus, we can remove the extra buffer completely"

This reverts commit a5e3c4f04ce0b36ed78c88a221ccca5a3d2bcd50.

I was too hasty in concluding this could be removed easily

OpenSubdiv: Continue working on skipping CCG creation

Synchronize topology refiner directly from derived mesh and skip CCG geometry
creation in that case.

Gets rid of annoying derived mesh pointer in the CCGSubSurf structure, but needs
to add some information for coarse vertices positions.

Drawing code is totally removed now, no partitioning or material setting happens,
this code needs to be adopted to the case of missing CCG geometry. Maybe this
will require having some extra arrays in the CCGSubSurf structure, but generally
memory usage will still be much less than the previous integration.

Port UV display to new design. As plus, we can remove the extra buffer completely

Port texture paint and mcolor GPU upload to new design

Textured and GLSL drawing for cddm except from tangent layer
now ported correctly to new display paradigm

error in last commit

Check range of triangles passed into new bvhtrees

Avoid crashesing on invalid data

Avoid using PySequence functions, instead use PySequence_Fast

to support same featureset but avoid slow lookups.

Also fixes refcount leak accessing verts.

Start move drawing code for cdderivedmesh to indexed/mpoly design.
This is WIP mostly to merge some work that gets rid of code we
don't really need to port.

zero 3rd member of 2d arrays passed to mathutils.kdtree

OpenSubdiv: Initial work related on skipping CCG geometry creation for GPU

The idea is to only allocate CCG geometry (CCGVert, CCGEdge and so on) only
int cases when CPU evaluator is used. In case when GPU rendering is enabled
we'll be creating topology refiner directly from DerivedMesh.

Still quite enough of work to be done, including bringing back GPU backend
synchronization code.
