Depsgraph: Avoid transitive relation from local transform to final

There is always an uber eval node on the way. so we can avoid creating
some relations here in order to speed up both construction time and
evaluation.

Fix T49981: New Depsgraph - When camera is on inactive layer, it does not evaluate constraints

Fix depsgraph: hair collision is actually enabled, so add the relations.

Depsgraph: Fix matrix_world driver source

Reported by Dalai in IRC, thanks!

Depsgraph: Rigid body simulation doesn't need explicit time relation

It'll be dependent on time via Time Source -> Rebuild RB World chain.

Depsgrpah: Fix missing animation update in movie clips

Depsgraph: Fix residue of debug-only code

Depsgraph: use more explicit parenthesis

Depsgraph: Fix infinite viewport object update in CYcles render mode

The issue was caused by wrong object re-tag needed to have proper dependnecies
update for OpenSubdiv.

Fix copy/paste typo in new depsgraph object geometry builder (found by coverity).

Depsgraph: Move scene builder function to own file

This way it's much easier to grasp what the graph actually contains.

Depsgraph: Fix typo in previous optimization commit

Was a residue from another experiment, caused infinite loop when
reporting dependency cycles.

Fix T50060: New depsgraph does not update mask animation

Depsgraph: Move rig builder functions to own files

Those routines are rather big and started to be annoying to have
one big file.

Should be no functional changes.

Depsgraph: Use utility macro to iterate over linked list

This will be compiled into same exact code, just saves us from
doing annoying type casts all over the place.

Atomics: Make naming more obvious about which value is being returned

Depsgraph: Fix typo in text on curve relation builder

Depsgraph: Add missing NULL pointer check

Fix T49993: Indirectly used taper/bevel crashes new dependency graph

New dependency graph expects strict separation between nodes and relations builder,
meaning, if we try to create relation with an object which is not in the graph yet
we'll have an error in depsgraph.

Now, so far object nodes were created from bases of the current scene, which caused
missing objects in graph in certain cases.

Didn't find better approach than to simply ensure object nodes exists when we know
they'll be used by relation builder.

Depsgraph: Fix missing DONE flag in relations builder

Was causing relations be build twice in certain cases.
