This changes fixes the slowdown when baking data passes like Normal with
the denoiser enabled on scene settings.
When baking to 4K textures denoising could take considerable amount of
time, which is better be avoided.

Cycles can use a per face flag to determine if a face is smooth or flat,
and there is no need to use corner normals in such cases. So revert to
not doing that as before, which also saves a bit of memory.
There is a pre-existing issue where faces are split by sharp edges and
autosmooth, which is not solved by this. It's only fixing the regression.
The pre-4.0 Principled BSDF had a special diffuse BSDF that contained
the roughness value from the node. Since 4.0, the regular Diffuse BSDF is used,
so we need to ignore it when determining the roughness value for baking.
Enable huge pages for jemalloc. This requests the Linux kernel to use
huge (2 MB) pages for large allocations. This has the effect of speeding
up first accesses to those allocations, and possibly also speeds up future
accesses by reducing TLB faults.
By default, 4 KB pages are used unless the user enables huge pages through
a kernel parameter or an obscure sysfs setting.
For Cycles benchmarks, this gives about a 5% CPU rendering performance
improvement. It likely also improves performance in other areas of Blender.

For default GetWindowUnderCursor (when there is not a platform-specific
version), search windows in reverse order. This is because in most
cases with overlapping windows the one that is on top was created after
those that are below it.

Caused by e968b4197b / 67e23b4b29
Since culprit commits, we are not running `MANTA::initGuiding` /
`fluid_alloc_guiding` if guiding is meant to be pulled from other
domains (it does work with effectors though). This is because atm. only
the `FLUID_DOMAIN_ACTIVE_GUIDE` flag sets `mUsingGuiding` to true
(activated in `update_obstacleflags`, so only for effectors).
So to fix this, we have to ensure that `MANTA::initGuiding` runs (also
if guiding is pulled from domains), but also make sure we dont run into
the crashes from T102257.
It seems that the real reason we were getting crashes in T102257 is that
67e23b4b29 made it so that resetting the cache (including a call to
`fluid_modifier_reset_ex`) in `fluid_modifier_processDomain` happens
**after** `FluidDomainSettings.active_fields` have been updated (this
happens in `update_flowsflags` & `update_obstacleflags`).
But `fluid_modifier_reset_ex` also resets
`FluidDomainSettings.active_fields`. If we then update pointers later in
`fluid_modifier_processDomain`, we never get anything in the guiding
related pointers for the new `mCurrentID` (specifically `mPhiGuideIn`
will be a nullptr). This is the real reason `initGuiding()` runs a
second time (it does once for `fluid_modifier_init` then again as a
consequence of the call to `manta_guiding`).
This patch proposes to move the resetting process from 67e23b4b29
**above** the refreshing of the `FluidDomainSettings.active_fields`,
this way these field stay intact, we do get the first run of
`initGuiding()` from `fluid_modifier_init`, manta pointers get updated
with intact fields afterwards (so we then get a valid `mPhiGuideIn`),
which then prevents the second run from `manta_guiding` to actually call
the python script again.
The fix from e968b4197b is then not needed and reverted in this patch.
This should be good for LTS I think.

The previous commit introduced a new `RPT_()` macro to translate
strings which are not tooltips or regular interface elements, but
longer reports or statuses.
This commit uses the new macro to translate many strings all over the
UI.
Most of it is a simple replace from `TIP_()` or `IFACE_()` to
`RPT_()`, but there are some additional changes:
- A few translations inside `BKE_report()` are removed altogether
because they are already handled by the translation system.
- Messages inside `UI_but_disable()` are no longer translated
manually, but they are handled by a new regex in the translation
system.

Fixes an issue where CPU specific render settings (e.g. path guiding)
would be hidden when GPU Compute has been selected for rendering,
but a GPU hasn't been selected in preferences.

In this case the object transform can use more motion steps, but the
geometry needs to have its motion steps fixed since the velocity
attribute completely overrides them.
There was one functional issue with the previous API which was its
use in `VolumeGrid<T>::grid_for_write(tree_token)`. The issue was
that the tree token had to be received before the grid is accessed.
However, this `grid_for_write` method might create a copy of the
`VolumeGridData` internally and if it does, the passed in `tree_token`
corresponds to the wrong tree.
The solution is to output the token as part of the method. This has two
additional benefits:
* The API is more safe, because one can't pass an r-value into the methods
anymore. This generally shouldn't be done, because the token should
live at least as long as the OpenVDB tree is used and shouldn't be freed
immediatly.
* The API is a bit simpler, because it's not necessary to call the
`VolumeGrid.tree_access_token()` method anymore.
Regression from [0] based on the incorrect assumption that X11's
Time was a uint64. Despite the `Time` type being 8 bytes,
the value wraps at UINT32_MAX.
Details:
- GHOST_SystemX11::m_start_time now uses CLOCK_MONOTONIC instead of
gettimeofday(..) since event times should always increase.
- Event timestamps now accumulate uint32 rollover.

When a mesh light is shadow-linked to something with a specific
shader network it was possible that the emission_sd_storage was
not bit enough for sampling.
The shade_dedicate_light kernel only evaluates emission of either
light or mesh emitter and then resumes the regular path tracer.
There is no need to store closures.
This change makes it so a smaller storage is used, and also
passes flag to the shader evaluation function indicating that
closures are not to be stored.

Bundling many tests in a single binary reduces build time and disk space
usage, but is less convenient for running individual tests command line
as filter flags need to be used.
This adds WITH_TESTS_SINGLE_BINARY to generate one executable file per
source file. Note that enabling this option requires a significant amount
of disk space.
Due to refactoring, the resulting ctest names are a bit different than
before. The number of tests is also a bit different depending if this
option is used, as one uses gtests discovery and the other is organized
purely by filename, which isn't always 1:1.

ROCm 6 brings some changes to the HIP API. This pull request is meant to be
backward and forward compatible.
That is Blender could be compiled with either ROCM 6 or 5 and run on either.
The main change is the hipMemoryType enum, which we check based on the
runtime version to use the correct enum values.
Without this, HIP will not work on Windows with upcoming 23.40 driver.

The IES parser in Cycles would lead to heap buffer overflow error
when non-supported or invalid data is provided to it.
The error was caused by the way how stirng is copied to vector
skipping the last null-terminator. Later C-style string utilities
are used for parsing, and they expect the data to be null-terminated.
It is unclear why data needs to be stored as vector: storing it as
string simplifies initialization.
Easiest to reproduce the issue is to use Blender build with address
sanitizer enabled.

Along with the 4.1 libraries upgrade, we are bumping the clang-format
version from 8-12 to 17. This affects quite a few files.
If not already the case, you may consider pointing your IDE to the
clang-format binary bundled with the Blender precompiled libraries.
The use-after-free is triggered when the GHOST system is created
multiple timers during the application timelife which happens in
the integration tests.
The solution is to release the application delegate and set it
to nil when the GHOST system is being destroyed. This ensures that
all subsequent GHOST systems properly initialize application
delegate, and that there is no application delegate which points
to a freed system.
The original issue was noticed by a flackey behavior of the
bf_gpu_tests test which was failing at random. The issue could
be reliably reproduced by running this test with ASAN enabled.

Fix issues related to NaN normals in some situations by trying
to detect when these cases might occur and just reverting back
to default normals.
As a side effect of these changes, OSL now behaves correctly
when given a non-normalized normal.
