Fix T43926: Volume scatter: intersecting objects GPU rendering artifacts
...
Fix T44007: Cycles Volumetrics: block artifacts with overlapping volumes
The issue was caused by uninitialized parameters of some closures, which
lead to unpredictable behavior of shader_merge_closures().

Cycles: change __device and similar qualifiers to ccl_device in kernel code.
...
This to avoids build conflicts with libc++ on FreeBSD, these __ prefixed values
are reserved for compilers. I apologize to anyone who has patches or branches
and has to go through the pain of merging this change, it may be easiest to do
these same replacements in your code and then apply/merge the patch.

isn't working well for OSL texture filtering and wasn't very helpful to begin
with, a better solution should be possible.
