Sergey Sharybin 55b24bef55 Depsgraph: Cleanup and code simplification
This is mainly a maintenance commit which was aimed to make work with
this module more pleasant and solve such issues as:

- Annoyance with looong files, which had craftload in them
- Usage of STL for the data structures we've got in BLI
- Possible symbol conflicts
- Not real clear layout of what is located where

So in this commit the following changes are done:

- STL is prohibited, it's not really predictable on various compilers,
  with our BLI algorithms we can predict things much better.

  There are still few usages of std::vector, but that we'll be
  solving later once we've got similar thing in BLI.

- Simplify foreach loops, avoid using const_iterator all over the place.

- New directory layout, which is hopefully easier to follow.

- Some files were split, some of them will be split soon.

  The idea of this is to split huge functions into own files with
  good documentation and everything.

- Removed stuff which was planned for use in the future but was never
  finished, tested or anything.

  Let's wipe it out for now, and bring back once we really start using
  it, so it'll be more clear if it solves our needs.

- All the internal routines were moved to DEG namespace to separate
  them better from rest of blender.

  Some places now annoyingly using DEG::foo, but that we can olve by
  moving some utility functions inside of the namespace.

While working on this we've found some hotspot in updates flush, so
now playback of blenrig is few percent faster (something like 96fps
with previous master and around 99-100fps after this change).

Not saying it's something final, there is still room for cleanup and
API simplification, but those might happen as a regular development
now without doing any global changes.
