Turned all DepsNode subtypes into actual subclasses of DepsNode.

Make use of the MEM_CXX_CLASS_ALLOC_FUNCS macro for DepsNode to define
the new/delete operators using guardedalloc.

Moved the DEG_graph_build_from_scene function into the public depsgraph
API header.

This way we can avoid including the internal (C++) header in rna_scene.c.

Merge branch 'master' into depsgraph_refactor

Revert "Basic DepsNode type in RNA and a root_node property in the Depsgraph."

This reverts commit 39b76f27bc4b8437bedb08dde46f968f81b8040f.

The depsgraph requires only a minimal RNA representation as a means for
debugging addons to access it and request debug dumps. Removing this
also avoids internal header includes.

Cluster graphviz output for generic component node types.

Tentative fixes for Pose Eval and related bone components and operations.

Handle the Pose Eval node type as a cluster in graphviz debug.

Renamed the scene depsgraph_rebuild filename argument to clarify that
this is for debugging only.

Support for debug graphviz output during the build process.

This uses two callbacks which can be set prior to rebuilding the
depsgraph. These will be called when nodes or relations are added, which
leaves the actual implementation up to the caller with minimal impact
on the depsgraph code.

These functions are stubs in non-debug modes, so they don't cause
overhead.

The Scene.depsgraph_rebuild() function implements this via an optional
filename argument. If this is specified it will dump build steps into a
sequence of files using _<N> suffixes with a running number N.

Fix for invalid FILENAME_MAX macro and missing includes in rna_depsgraph.

Nicer font for graphviz debug output.

General support for subgraph nodes.

Color tweaks:
* Use explicit color values (hex format) instead of predefined schemes
for more control and larger palettes.
* Disabled: edge coloring (not very useful because hard to distinguish).

Show a legend in the graphviz output.

Invert edge direction to better reflect the meaning of a "dependency".

Handle internal relations of component nodes.

Display nested node graphs using graphviz' cluster syntax.

Renamed the 'class' in DepsNode to 'tclass' to avoid the C++ keyword.

For the compiler this doesn't make a difference since it's C code, but
IDEs will have trouble identifying the struct member correctly.

Use different graphviz styles based on the node class.
