This is an initial implementation of BVH8 optimization structure
and packated triangle intersection. The aim is to get faster ray
to scene intersection checks.

As memory goes, peak usage raises by about 4.7% in a complex
scenes.
Note that BVH8 is disabled when using OSL, this is because OSL
kernel does not get per-microarchitecture optimizations and
hence always considers BVH3 is used.
Original BVH8 patch from Anton Gavrikov.
Batched triangles intersection from Victoria Zhislina.
Extra work and tests and fixes from Maxym Dmytrychenko.

With small tiles, the repeated allocations on GPUs can actually slow down the denoising quite a lot.
Allocating the buffer just once reduces rendertime for the default cube with 16x16 tiles and denoising on a mobile 1050 from 22.7sec to 14.0sec.

I wouldn't mind changing style to have space after keyword, but there was
no official code style change proposed.

Was only happening for release builds made with GCC-8. Probably some
optimization strtegy was confused by uninitialized variable.

Building the CUDA kernels takes quite a bit of memory, and when building all of
them the combined usage can be too much on some systems (especially VMs).
Therefore, this patch adds an option to force the build system to build them
sequentially by making each build step depend on the previous kernel.

Makes it more clear whether compute device is Vega 56 or Vega 64.

Currently unused, but will allow to convert unknown

fileno could be a macro which can't take a void pointer.

This is in preparation of upgrading our library dependencies, some of which
need C++11. We already use C++11 in blender2.8 and for Windows and macOS, so
this just affects Linux.
On many distributions this will not require any changes, on some
install_deps.sh will need to be run again to rebuild libraries.

Just basic algebra - because all vectors have the same z coordinate, a lot of terms end up cancelling out.
Not exactly a massive improvement, but it's measurable with Branched PT and a high sample count on the lamp.

Gathers information about object geometry and textures. Very basic at
this moment, but need to start somewhere.
Things which needs to be included still:
- "Runtime" information, like BVH. While it is not directly controllable
by artists, it's still important to know.
- Device array sizes. Again, not under artists control, but is added to
the overall size.
- Memory peak at different synchronization stages.
At this point it simply prints info to the stdout after F12 is done,
need better control over that too.

There is no reason or justification to have helper functions as
class methods: they do not depend on anything in the class itself.
There are probably more cases like that.

Allows to catch enumerator values which are missing from being handled.
Also use `const char*`, no need to construct string just to throw it away.

While changing the shading normal is a great way to add additional detail to a model, there are some problems with it.
One of them is that at grazing angles and/or strong changes to the normal, the reflected ray can end up pointing into the actual geometry, which results in a black spot.
This patch helps avoid this by automatically reducing the strength of the bump/normal map if the reflected direction would end up too shallow or inside the geometry.

The old springs with damping 1.0 operate in a special way that
is more similar to plastic deformation than a spring. Some users
rely on that, so let the user choose which implementation to use.
This also restores full backward compatibility with 2.79.

This increases stack memory usage some, and ideally we'd support a dynamic
size. But this is quite difficult on the GPU and hopefully 32 is enough even
for very complex cases.

This is a physically-based, easy-to-use shader for rendering hair and fur,
with controls for melanin, roughness and randomization.
Based on the paper "A Practical and Controllable Hair and Fur Model for
Production Path Tracing".
Implemented by Leonardo E. Segovia and Lukas Stockner, part of Google
Summer of Code 2018.

So far only noticed system de-initialization doesn't perform full
object free. So rather harmless but yet stupid.

Features to get the 2nd, 3rd, 4th closest point instead of the closest, and
various distance metrics. No viewport/Eevee support yet.

This works for Cycles, Eevee, texture nodes and compositing. It helps to
reduce the number of math nodes required in various node setups.

The X resource database is to be explicitly destroyed. This fixes 46 bytes
leak per every window DPI query (which happens a lot on window move/resize
and even on areas resize).
Unfortunately, this does not fully fix the leak since the known leak:
