Skeleton logic for creating groups

First pass at some node copy logic - ID and Group nodes only so far

Added default handling for relationships on copied nodes

For now, resolution is to clear lists of links when doing base-node copy
(as we have no/little knowledge of what to do with regards to how this
links in with rest of tree).

However, callers of this node should know a bit more
(i.e. when copying node's subtree, at least level n-1 knows
how to solve the links between nodes at level n, though we still have
problems with links which stray to other nodes outside this one...

Skeleton of node copying operation

* Added an API method for copying a node (and its little subgraph)
* TODO: The handling of in/out links needs to be resolved...

Improve comment for nti->match_outer() callback

DEG_group_cyclic_nodes() -> DEG_group_cyclic_node_pair()

This renaming change makes it clearer what exactly the function does.
That is, instead of being the "global" entrypoint for all cyclic node
grouping operations, this only performs grouping for a single pair of
cyclic nodes...

More code reshuffling - moving around prototypes (and argument definition lists)

Code reshuffling for core/general node management routines

Abstract out standard part of IDDepsNode and GroupDepsNode into a separate type

This makes it easier to tell whether they've been defined correctly,
and/or gives us a legitimate type (OuterIdDepsNodeTemplate) to use when
dealing with a node which we know is either one (and the exact difference
doesn't matter).

Add slot in typeinfo for callback to be used when removing a node from graph

The main purpose of this is so that we can replace ID nodes with ID Groups
by removing the old ID nodes and merging their contents into a new group
node.

As a result, shuffled about the order of callbacks a little in typeinfo

Draft "add_to_graph()" method for groups

NOTE: this probably won't work out as-is if we use the standard node
add methods, as there are no ID refs set yet when using that method...

Typeinfo defines for node types

DEG_get_typeinfo() -> DEG_get_node_typeinfo()

Remove temp todo comments left in as reminders

These are no longer needed as there are now nodes which demonstrate what
each of these should be like.

Rename fix - Fix for one old reference of "DatablockDepsNode"

Finish logic for finding matching data nodes

Add some missing #includes

Finish off "add to graph" for data node

Start of logic for node types

Stubbing in more graph building stuff * Start of AnimData building * Objects loop
