Instead of printing debug flags listing various CPU and GPU settings that
may or may not be used, print when we are using them. This include CPU
kernel types, OptiX debugging and CUDA and HIP adaptive compilation. BVH
type was already printed.
Looks like OSX changed the default format of its locale, which is not
valid anymore for gettext/boost::locale.
Solution based on investigations and patch by Kieun Mun (@kieuns), with
some further tweaks by Ankit Meel (@ankitm), many thanks.
Also add an exception catcher on `std::runtime_error` in
`bl_locale_set()`, since in OSX catching the ancestor `std::exception`
does not work with `boost::locale::conv::conversion_error` and the like
for some reasons.

The current UI for the Scramble Distance patch is grayed out
depending on different settings that are enabled. However it
didn't make much sense to me so I have updated when the UI is
grayed out to hopefully make more sense to the end user.

Adds scrambling distance to the PMJ sampler. This is based
on the work by Mathieu Menuet in D12318 who created the original
implementation for the Sobol sampler.

saturate is depricated in favour of __saturatef this replaces saturate
with __saturatef on CUDA by createing a saturatef function which replaces
all instances of saturate and are hooked up to the correct function on all
platforms.

Cycles:Distance Scrambling for Cycles Sobol Sampler
This option implements micro jittering an is based on the INRIA
research paper [[ https://hal.inria.fr/hal-01325702/document | on micro jittering ]]
and work by Lukas Stockner for implementing the scrambling distance.
It works by controlling the correlation between pixels by either using
a user supplied value or an adaptive algorithm to limit the maximum
deviation of the sample values between pixels.

Remove prefix of filenames that is the same as the folder name. This used
to help when #includes were using individual files, but now they are always
relative to the cycles root directory and so the prefixes are redundant.
For patches and branches, git merge and rebase should be able to detect the
renames and move over code to the right file.
* Split render/ into scene/ and session/. The scene/ folder now contains the
scene and its nodes. The session/ folder contains the render session and
associated data structures like drivers and render buffers.
* Move top level kernel headers into new folders kernel/camera/, kernel/film/,
kernel/light/, kernel/sample/, kernel/util/
* Move integrator related kernel headers into kernel/integrator/
* Move OSL shaders from kernel/shaders/ to kernel/osl/shaders/

Add a Fast GI Method, either Replace for the existing behavior, or Add
to add ambient occlusion like the old world settings.
This replaces the old Ambient Occlusion settings in the world properties.
This is still useful in some cases even if not used by OpenImageDenoise. In
the future this may be replaced with a more generic system to control render
passes and filtering, but for now this just does what it did before.
Panning in camera view makes the border to be modified, which was causing
the Cycles display to believe the rendered result is unusable.
The solution is to draw the render result at the display parameters it was
updated for. This allows to avoid flickering during panning, zooming, and
camera FOV changes. The suboptimal aspect of this is that it has some jelly
effect, although it is on the same level as jelly effect of object outline
so it is not terrible.

The idea is to allow having a lot of non-intersecting volumes without
allocating volume stack to its full size.
With the F11285472 file the memory usage goes from 1400 MiB to 1000
on the RTX6000 card.
The fix makes it so the integrator work memory is allocated after
scene update which has downside of possible less efficient update
when some textures don't fit GPU memory, but has an advantage of
making proper decision and having a clear and consistent internal API.
Fixes memory part of T92014.

The approach didn't turn out to be that useful after all as there
are unavoidable dependencies of data from the device. For example,
to know whether object intersects volume or not it is required to
run displacement kernels.
The way of splitting host and device updates caused state where
some data is not yet available, causing confusion and leaving
code to be error-prone.
* Additional structs added to the hipew loader for device props
* Adds hipRTC functions to the loader for future usage
* Enables CPU+GPU usage for HIP
* Cleanup to the adaptive kernel compilation process
* Fix for kernel compilation failures with HIP with latest master
Ref T92393, D12958
Mention required CUDA and OptiX compute capability and minimum driver
version. For HIP there is a placeholder until we know the supported
architectures.
This triggered a compiler bug where it does not handle the sub.s16 PTX
instruction. Instead refactor the code so we don't need to do uint16_t
subtraction at all.
Also update OptiX device to remove the AO pass direct callable.
Thanks Patrick Mours for figuring this out.
Similar to main path compaction that happens before adding work tiles, this
compacts shadow paths before launching kernels that may add shadow paths.
Only do it when more than 50% of space is wasted.
It's not a clear win in all scenes, some are up to 1.5% slower. Likely caused
by different order of scheduling kernels having an unpredictable performance
impact. Still feels like compaction is just the right thing to avoid cases
where a few shadow paths can hold up a lot of main paths.

Apple's international keyboards have an additional `kVK_ISO_Section`

Right now this key is explicitly set as `Unknown`.
