Renaming graph->root to graph->root_node, as used in graph building code

Increasing whitespace

Add a hashtable on depsgraph (just like in trunk) for quickly finding node for ID

Jotting down more logic for finding nodes...

* ID Nodes
* Data nodes within ID nodes

Start of node search code...

This is all still quite crude, and eventually, we may just move all this
to be the lowest level of the querying API...

Define a few more node type register calls

Added comment detailing current decision to use hash vs array for typeinfo registry

Node types registry - Use a GHash for now

This makes it easy when dealing with the types, which can now have arbitrary
codes given to them, instead of having to be tightly packed.

However, this may turn out to be overkill, since we only really have a few
core node types, so using an array may prove to be a better strategy overall...

New node adding code fleshed out to use typeinfo

Added another callback in typeinfo for handling outer-node queries

Start of node typeinfo handling

* All (core) nodetype defines will now be in depsgraph_type_defines.c
* Made a few tweaks to make the API's nicer
* Still need to figure out how to define the rest

Defining typeinfo for core node types, and a little API to work with these

Renamed "DatablockDepsNode" to "IDDepsNode"

While the former was perhaps more descriptive (and looks slightly better),
it also feels like too much of a mouthful to use, besides not really
being that clear that it wraps an ID datablock.

Draft stub for creating a group node (as necessary) during graph building

Change argument types for low-level node management functions

Apparently it is not possible to simply pass on the list of arbitrary
arguments down the chain that easily (where the list grows and shrinks
according to the needs of the specific API used). So instead, always use
the full version.

Alternative here is to just have separate copies for each case?

First skeletal draft of the internal node management functions

* DEG_get_node() is fully fleshed out
* DEG_add_node() and DEG_find_node() still need to be figured out...

Renaming "data" mid-level outer node type

Having "MID" in the name was a bit dodgy from an API standpoint in the
long run, even if that would have made things a bit clearer as to where
it stands between the levels.

Added a new header for "internal" depsgraph API functions

These are mainly functions which can be used internally within the
Depsgraph, and/or are exported between various parts of the internals
but which shouldn't really be exposed to the outside world (i.e. other
parts of Blender outside of the depsgraph module).

Will review later whether this file is really needed or whether it can
be folded into some of the other headers)

Replace all DAG_add_node() calls with DAG_get_node() calls in the graph building

This is needed so that nodes that others depend on can get added ahead of
time...

Noted potential problem with the way we're trying to build depsgraph nodes
