This allows adding a "fake" sun beam effect, simulating crepuscular rays
from light being scattered in a medium like the atmosphere or deep water.
Such effects can be created also by renderers using volumetric lighting,
but the compositor feature is a lot cheaper and is independent from 3D
rendering. This makes it ideally suited for motion graphics.
The implementation uses am optimized accumulation method for gathering
color values along a line segment. The inner buffer loop uses fixed
offset increments to avoid unnecessary multiplications and avoids
variables by using compile-time specialization (see inline comments
for further details).
Baking progress preview is not possible, in parts due to the way the API
was designed. But at least you get to see the progress bar while baking.

This is a much simpler fix to that libyaml-cpp mess, since doing it that way we get our static own
libyaml-cpp... And this should work for all platforms (realized libymal-cpp-ver option was only
implemented for deb-like distro, since it was the first place where issue showed up :/ ).
Also extended the size of buf[] in print_error() to prevent mem_printmemlist_pydict_script[]
from getting truncated when MEM_printmemlist_pydict() is used.

bmesh's 'Join Edge Kill Vert' was using own code to delete loops, instead of
using `bm_kill_only_loop()`, which did not tag loop indices as dirty (causing
the crash), but also did not free loop's CDData...
In addition to D319, this patch updates the parameter editor, the UI of Freestyle.
Using new API functionality and experience gained in making D319, this patch
provides a quite noticable speedup for commonly-used Freestyle linestyle modifiers.
As this patch touches a lot of code (and mainly the foundations) it is likely that
mistakes are made. The patch has been tested with a regression suite for Freestyle
(https://github.com/folkertdev/freestyle-regression-tests/tree/master), but testing
with scenes used in production is very much appreciated.

Issue with previous code was that branch selected was applied to all repositories.
To be able to control branch on a per-repo basis, we need to use codebases instead.
This commit only enables branch (master/testbuild) and revision selection for master,
we probably do not need this for submodules currently (easy to enable anyway).
Note: tested on local buildbot setup, for linux only (up to build step, have no build env).
If the active image node contributes to the final material shader
(meaning it's either directly or indirectly connected to an Output Node)
the user will receive an alert about circular dependency.
Similar to what we do for Blender internal the baking will still happen,
but the user will receive the alert which should prevent the image
saving to happen if the result was not intentional.
