Changes to ED_node_shader_default() were reverted since the code there was actually
not suitable for setting up the default line style node tree properly.
Now the shader node tree of a line style ID datablock is used to define textures
as well as their mapping and influence.
TODO: Textures alpha channel mapping and influence.
TODO: Blend mode in the Output Line Style shader node.
We can't really make CPU and GPU results look the same in all possible
circumstances, but here we can make them look close enough to each other
by making it so sobol pattern for bounce number is the smae for both
CPU and GPU.
This makes CPU and GPU render results look the same with low number of
samples, high number of samples was never an issue.
The issue is that we've got hell with DEBUG and _DEBUG,
theu're defined really inconsistent acros CMake and SCons.
Used more reliable NDEBUG definition for IDP_spit.
The issue was caused by the wrong attributes maps in certain
circumstances after union intersections.
Namely issue might have happen when more than one iteration of
union was happening and it was caused by the fact that new faces
might be allocated on the same address as freed face from the
old mesh.
Didn't find a nicer fix for this apart from correcting the whole
attributes map after each union step.
We could try removing attributes for the meshes which are getting
deleted, but in asymptotic it's gonna to give exactly the same
complexity as the current approach.
This commit merges the code in the pie-menu branch.
As per decisions taken the last few days, there are no pie menus
included and there will be an official add-on including overrides of
some keys with pie menus. However, people will now be able to use the
new code in python.

Thanks:
Campbell Barton, Dalai Felinto and Ton Roosendaal for the code review
and design comments
Jonathan Williamson, Pawel Lyczkowski, Pablo Vazquez among others for
suggestions during the development.
Special Thanks to Sean Olson, for his support, suggestions, testing and
merciless bugging so that I would finish the pie menu code. Without him
we wouldn't be here. Also to the rest of the developers of the original
python add-on, Patrick Moore and Dan Eicher and finally to Matt Ebb, who
did the research and first implementation and whose code I used to get
started.
Was more a feature request actually, but anyway...
Note this is a bit more complex than it's vgroups counterpart, since we have to handle
relations between keys (relative keys, and position for absolute ones).
This assert happens all the time for character physics in debug mode.
In release mode, the assert is skipped but the code is still incorrect
although it does not cause any crash strangely.
