Various improvements to obj preview generation:

* Do not render cameras, lamps etc. for now.
* Generate bbox in camera local space, gives much better results.
* Add an op to clear previews from files.

Depsgraph: Remove unused includes

Merge branch 'master' into asset-experiments

Tweaks to where placeholder ops for geometry eval go

The original intention here was that operation nodes for geometry would go
on the geometry datablocks. Currently, these are added to the object datablock
instead so that it works with old files.

The main result of this change is a lot of the relation-building code now works
correctly again, since there's only a single node again in the geometry component there.

Stop handling pose eval in obdata ubereval

Depsgraph: Fix wrong memory access in debug dump

It's not possible to have stuff like

const char *foo = bar().c_str()

in cases when bar() returns dynamically allocated string.

Merge branch 'master' into gooseberry

Depsgraph: Add utility functions for eval_ctx allocation/free

This started as an experiment about different aspect of dependency graph,
but this is gonna to be handy anyway when we'll need to couple evaluation
context with the storage.

Merge branch 'master' into depsgraph_refactor

Depsgraph: Code cleanup, unneeded forward declarations

Drivers affecting modifiers now get hooked up to the relevant modifier node

Code cleanup: Reshuffled + removed duplicate lookup

activate objects now when constraints are broken, this is an attempt to get rid of single shards stuck in the air, not being connected visually to other shards

Merge branch 'master' into asset-experiments

First basic pyscripts to generate previews for objects.

Much to be done still, but with it you can select some blender file,
and generate a basic rendered preview of each object.

Depsgraph: Code cleanup, no need to have public deg_schedule_children now

find_nearest implementation for bmesh BVHTree type.

This uses only mesh vertices, since this function is supplied by the
bmesh bvhutils. Nearest face lookup could be added later.

Depsgraph: Move task callback to the depsgraph_eval file

It's just more a hassle of having separate file and some public-ish
API to pass all the data around. Easier just have single file with
all evaluation.

Depsgraph: Avoid having one global lock for all the graphs

That's a bit crazy to have single global lock in the .cpp file which
could be easily coupled into Depsgraph structure so it would never
interfere if several threads traverses the graphs.

Depsgraph: A bit more cleanup

Hopefully it's only me who touches this areas atm.
