This helps making things clearer and cleaner. Func returning filepath of
G.main is separate, so that we can easily track its usages, and
hopefully deprecate it at some point. Though that usage of G.main is
likely the less evil one, you nearly always want current blendfile path
in those cases anyway.
This is really convenient for development. Either for profiling the
generated shaders or to check if the generated code is correct.
It writes the shaders to the temporary blender session folder.

This commit contains the minimum to make clang build/work with blender, asan and ninja build support is forthcoming
Things to note:
1) Builds and runs, and is able to pass all tests (except for the freestyle_stroke_material.blend test which was broken at that time for all platforms by the looks of it)
2) It's slightly faster than msvc when using cycles. (time in seconds, on an i7-3370)

3) clang on windows uses a drop in replacement for the Microsoft cl.exe (takes some of the Microsoft parameters, but not all, and takes some of the clang parameters but not all) and uses ms headers + libraries + linker, so you still need visual studio installed and will use our existing vc14 svn libs.
4) X64 only currently, X86 builds but crashes on startup.
5) Tested with llvm/clang 6.0.0
6) Requires visual studio integration, available at https://github.com/LazyDodo/llvm-vs2017-integration
7) The Microsoft compiler spawns a few copies of cl in parallel to get faster build times, clang doesn't, so the build time is 3-4x slower than with msvc.
8) No openmp support yet. Have not looked at this much, the binary distribution of clang doesn't seem to include it on windows.
9) No ASAN support yet, some of the sanitizers can be made to work, but it was decided to leave support out of this commit.

This patch adds support for IES files, a file format that is commonly used to store the directional intensity distribution of light sources.
The new IES node is supposed to be plugged into the Strength input of the Emission node of the lamp.
Since people generating IES files do not really seem to care about the standard, the parser is flexible enough to accept all test files I have tried.
Some common weirdnesses are distributing values over multiple lines that should go into one line, using commas instead of spaces as delimiters and adding various useless stuff at the end of the file.
The user interface of the node is similar to the script node, the user can either select an internal Text or load a file.
Internally, IES files are handled similar to Image textures: They are stored in slots by the LightManager and each unique IES is assigned to one slot.
The local coordinate system of the lamp is used, so that the direction of the light can be changed. For UI reasons, it's usually best to add an area light,
rotate it and then change its type, since especially the point light does not immediately show its local coordinate system in the viewport.

This commit adds number formatting (thousands separator) to the baking panel. It also adds a new function to format memory sizes (KB/GB/etc) and applies it to the baking panel and scene stats. The new function is unit tested.

Freeing sequencer would always do usercount, which is now forbidden when
called from main ID freeing code.
Annoying in 2.7x, much more critical issue in 2.8!
Also, moved RNA sequencer API functions to proper rna_scene_api.c file.
Readcode always set relative paths of indirectly linked libs relative to
*current* .blend file, not to the library using it.
But BKE_library_filepath_set was then setting them relative to their
parent library, breaking checking code (and saved files even :((( ).
Some years-old deprecated stuff has now been removed.
Correct solution is probably to use valid defines etc. in own code, but
this is more FFMEPG maintainer task (since it also may change how old
FFMPEG we do support...).
The value of epsilon was never used to create this bvhtree because whenever we activate this constraint, a bvhtree with parameter epsilon 0.0 was created and cached.
`MREMAP_RAYCAST_APPROXIMATE_BVHEPSILON(ray_radius)` greatly increased the radius making for example that 0.1 becoming 1.5
Now the result is much more predictable.
