Depsgraph: Code cleanup

'expand' function for cache libraries, so link/append makes it load the
group and objects too.

Make cache libraries a linkable data block.

Take NULL object pointers in cache items into account.

This can happen if an object gets deleted or isn't loaded for some
reason. The item should just be ignored in that case and removed at the
next opportunity (cleanup function).

Depsgraph: Correction to previous commit

Update for the new frame happens a bit different and previous commit broke animation.

When using the "new cache library" operator, enable fake user by
default.

Nothing actually links to a cache library at this point (and probably
won't in the future), so fake user is necessary to avoid losing data.

Display cache library name and fake user button, imitating template_ID.

Importing of caches into Blender data.

Currently only implemented for DerivedMesh.
This replaces the `final_dm` calculation of the modifier stack with the
result from cache loading.

Depsgraph: Make sure recalc is flushed before calling scene update handlers

Depsgraph: Fix missing updates after recent visibility changes

After some additional thoughts it's now not totally clear for me if we really
want flush to happen on invisible objects or not. Will think about it in more
details..

UI fixes, draw bake operator button only once at the top.

Hair path writer needs 2 different variants for parent/child hairs.

Depsgraph: Make sure changing DOF keeps valid depsgraph

Not sure how it worked in master branch actually, maybe we need to do
something like this there as well.

Added writers for derived mesh result and hair paths.

Depsgraph: Correction for camera DOF relation

For now it's unclear how to handle it on the camera datablock level,
so moved parameters to the camera object level.

This kinda of makes sense because for DOF you need to know object
matrix and having DOF decoupled from it is kinda weird.. IN any case
it's always easy to make it camera data relation and add relation
between camera datablock and camera object.

Depsgraph: Make error print a bit more verbose

Use explicit name strings for all readers/writers in the cache instead
of constructing names internally.

This helps prevent name collisions and guarantees a consistent naming
scheme for putting multiple items in the same cache.

New reader/writer for DerivedMesh.

Used as a base for existing PointCacheModifier classes, but can be used
on its own.

Merge branch 'master' into depsgraph_refactor

General support for export to/import from Alembic files based on Cache
Libraries.
