Depsgraph: Compile fixes on mingw

Seems that there were still too many headers removed, with sprintf and BLI_sprintf
not available.

Depsgraph: Removed a bit too much in the previous commit

Depsgraph: headers cleanup

Mainly avoid headers include from headers.

Depsgraph: Fix compilation error after ogdf commit

CMake should work now (ogdf stays disabled), should be no functional
changes for scons.

Depsgraph WIP: Ensure edges get added between nodes to show ownership hierarchies

We can't really test that this looks right yet, since we don't have a layout
algorithm working, but when this works, it will be necessary for identifying
what an opnode is for.

Depsgraph WIP: Stubbed in a few different layout engines for OGDF - still no dice

Depsgraph WIP: Disable superfluous debug prints

Depsgraph WIP: Removing unnecessary attributes for graph

These were resulting in nodes being created with sizes of 0,0, as those flags
expect that you manually set what you want.

Depsgraph WIP: Basic support for OGDF export

This introduces initial preliminary support for OGDF export, including the
code to populate the graph, and all the supporting operator/rna stuff.
Much of this has been copied + adapted from the code for the GraphViz
exporting, though we are likely to need to adapt this later on.

* Currently, there is no layout engine used, so the exported graph won't look
like anything exists. But, at least all the data does get exported.

* Debugging Note: Crashes related to the ogdf string class when assigning to attributes
occur if you don't set the GraphAttributes flag corresponding to that attribute.

Depsgraph WIP: Start of OGDF graph export

Useful Notes:
* The OGDF headers have to come before the Blender ones, or else the code will
NOT compile under mingw64 (and potentially a few others). In particular, this
results in many non-sensical errors in windef.h, windows.h, and winreg.h, potentially
arising from redefined or already defined constants.

Import v2012.07 of OGDF into extern libs

As a quick test, this imports OGDF into the source tree (later it could be removed
and added as a prebuilt static lib instead). The intention here is to use it for
drawing the debug graphs for the depsgraph.

Only scons is supported right now.

Depsgraph: Compile fix for pchanmap

Depsgraph: Tweaks to make graphviz-neato debug graphs more legible

Dot will crash when graphs are generated using this option, but for neato graphs,
at least we can see what the different items are this way.

Depsgraph: Add debug print to bone done callback

Depsgraph: Move root pchan map to own file

Depsgraph: Fix non-initialized operation flags

This was in fact root of the issue of victor rig i was having for
quite some time now.

Merge branch 'master' into depsgraph_refactor

Conflicts:
release/scripts/startup/bl_operators/anim.py

Depsgraph: Add dirty check for whether bone was updated or not

Depsgraph: Whole IK chain depends on the solver result

This is the only way we can make sure all needed calculations are done
to the time BKE_pose_bone_done() is called.

Depsgraph: Use BLI_gset_add() instead of BLI_gset_insert() to avoid duplicate entries in set

So it turns out that using BLI_gset_insert() will just cause the ghash-set
implementation to blindly add duplicate entries if the key already exists
in the hashtable - not exactly what we want, as that kindof violates the
whole point of such data structures.
