For now we work this around by copying python DLL to the
bin folder. Ideally the DLL should be shared between blender
and python, but that's a bit tricky to do on windows.
We had some reports where users did not even read the "Not supported on
release builds" message, and arguably writing a file sort of indicates
that the file may include something useful.
This way it is possible to have single threaded depsgraph but threaded other areas
which is handy for torubleshooting.

This commit integrates the work done so far on the new dependency graph system,
where goal was to replace legacy depsgraph with the new one, supporting loads of
neat features like:
- More granular dependency relation nature, which solves issues with fake cycles
in the dependencies.
- Move towards all-animatable, by better integration of drivers into the system.
- Lay down some basis for upcoming copy-on-write, overrides and so on.
The new system is living side-by-side with the previous one and disabled by
default, so nothing will become suddenly broken. The way to enable new depsgraph
is to pass `--new-depsgraph` command line argument.
It's a bit early to consider the system production-ready, there are some TODOs
and issues were discovered during the merge period, they'll be addressed ASAP.
But it's important to merge, because it's the only way to attract artists to
really start testing this system.
There are number of assorted documents related on the design of the new system:

* http://wiki.blender.org/index.php/User:Nazg-gul/DependencyGraph
There are also some user-related information online:

Kudos to everyone who was involved into the project:
- Joshua "Aligorith" Leung -- design specification, initial code
- Lukas "lukas_t" Toenne -- integrating code into blender, with further fixes
- Sergey "Sergey" "Sharybin" -- some mocking around, trying to wrap up the
project and so
- Bassam "slikdigit" Kurdali -- stressing the new system, reporting all the
issues and recording/writing documentation.
- Everyone else who i forgot to mention here :)
We need to register the exception handler slightly differently here, as
well as adding DbgHelp as a library, but according to docs it should be
supported in recent Windows editions (Win XP included even).
We can try it first and revert if there are issues.
This way both BLI_assert() and abort() called directly shouldn't
leave any files in the temp folder.
Previously it was really possible to have gadzillions of files
left over because of assert failures and debug aborts during the
development process.
This was rather annoying, since if you were script-editing a .blend file in background
mode, opened through this commandline option system, and wanted to save over,
a mere `bpy.ops.wm.save_mainfile()` *would not* overwrite expected file,
but instead write/replace the dummy `untitled.blend` one!
They're not intended to be executed directly and seems mode change happened
by accident.
Setting -x for this files to avoid possible incidents by trying to run this
files in shell.
The was caused by numpy never unpackign because of no
dpependnecy of any targets from the unpacked numpy.
Tried making it so blender target dpeends on it, but for
some reason it didn't work. For now added dedicated target
for unpacked numpy. A bit dirty but much better than just
totally failing.
This is mainly to address old issue when one need to have SDL library installed
in order to use our official builds. Some hip distros already installs SDL,
but it's not quite the same across all the variety of the distros.
We also now switching to SDL-2.0, most of the distros have it in repositories
already, so it shouldn't be huge deal to install it if needed.
