rB67e23b4b2967 revealed the bug. But the bug already existed before,
it just wasn't triggered.
Apparently the problem happens because the python code generated in
`initGuiding()` cannot be executed twice.
The second time the `initGuiding()` code is executed, the local python
variables are removed to make way for the others, but the reference to
one of the grids in a `Solver` object (name='solver_guiding2') is still
being used somewhere. So an error is raised and a crash is forced.
The solution is to prevent the python code in `initGuiding()` from being
executed twice.
When `FLUID_DOMAIN_ACTIVE_GUIDE` is in `fds->active_fields` this
indicates that the pointer in `mPhiGuideIn` has been set and the guiding
is already computed (does not need to be computed again).

This patch generalizes the OSL support in Cycles to include GPU
device types and adds an implementation for that in the OptiX
device. There are some caveats still, including simplified texturing
due to lack of OIIO on the GPU and a few missing OSL intrinsics.
Note that this is incomplete and missing an update to the OSL
library before being enabled! The implementation is already
committed now to simplify further development.

The distinction existed for legacy reasons, to easily port of Embree
intersection code without affecting the main vector types. However we are now
using SIMD for these types as well, so no good reason to keep the distinction.
Also more consistently pass these vector types by value in inline functions.
Previously it was partially changed for functions used by Metal to avoid having
to add address space qualifiers, simple to do it everywhere.
Also removes function declarations for vector math headers, serves no real
purpose.

Seems like the new audio channel api was not as backwards compatible as we thought.
Therefore we need to reintroduce the usage of the old api to make older ffmpeg version be able to compile Blender.
This change is only intended to stick around for two releases or so. After that we hope that most Linux distros ship
ffmpeg >=5.0 so we can switch to it.

This patch tunes maximum threads-per-threadgroup and threads-per-block for faster renders on Apple GPUs. Appropriate tuning is selected based on the GPU architecture (M1 or M2). We see a benchmark uplift of around 5-10% on M1 family chips. Similar uplift is expected on M2 with upcoming OS changes. (Ref T101931)

On Ubuntu 20.04 running X11, there was this message on every Blender startup:
Unable to find 'wl_proxy_marshal_flags' in 'libwayland-client.so.0'.
The reason is that we build against Wayland protocols 1.21, which in turns requires
Wayland on the distribution to be 1.21+, which is not the case on Ubuntu 20.04.
This simply silences the warning. An improvement would be to explain the user that
their Wayland version is too old when neither X11 or Wayland can be found. Though
that's not trivial and a situation with old Wayland and no XWayland seems unlikely
to happen in practice.

The non-deprecated API dates back to 2017, so it should be safe

The new Xcode declares the `sprintf()` function deprecated and
suggests to sue `snprintf()` as a safer alternative.
This change actually moves away from any formatted printing and
uses inlined byte-to-hex-string conversion which is also safe
and is (unmesurably) faster.

Seems to be introduced by 99e5024e97.
The crash is caused by the difference in the expected alignment
of the `uiPopupMenu` which is 16 bytes and the actual alignment
returned by the `MEM_mallocN()` which is 8 bytes due to the memory
head.
Now made it so that `MEM_new()` can be used for types with any
alignment.

Support layouts such as AZERTY where the shift key is held for number
keys. Text entry remains unchanged but these keys now activate shortcuts
as expected.
This matches a fix in X11 for the same problem: T47228.
This isn't full multi-seat support, instead set the active seat using
pointer/tablet & keyboard enter handlers.
This means that seats beside the first aren't prevented from having
their events handled.
This can be used for example for VR video formats that use this projection
instead of perspective projection for cubemap faces.

A copy of the clipboard was always being, changes would re-read it.
Now read the clipboard on request. This avoids having to keep a copy
of the clipboard in memory as well as the need to keep a thread
to running to read the clipboard for each data-offer.
To prevent a deadlock when pasting from Blender's own clipboard.
- Sending the clipboard (using write(..)) runs in a background thread.
- Reading the clipboard uses a thread that performs round-trips to the
Wayland server to prevent until the read is complete.
This is an update to [0] that resolves the deadlock.

When the Wayland pipe can't be opened, don't leave the mutex locked.
Also skip checking wl_data_device_manager when reading from the primary
clipboard.
There were two issues caused by deferred registration (added by [0]),
one crash on startup (T102075), another unreported issue with the GLX/EGL
context failing to initialize. Unfortunately I'm unable to reproduce the
errors but it seems likely deferring interface registration is not well
supported so this commit uses an alternative solution to some interfaces
depending on others for initialization.
Instead of relying on the order of registration, a separate "update"
callback has been added which is called after binding interfaces.
This has the advantage that it can be called when adding/removing
interfaces at run-time to avoid the dangling pointers being left in
locally allocated structures. In practice adding/removing interfaces
happens so rarely (only with "outputs" as far as I'm aware) that this
benefit is theoretical at the moment.
This should resolve T102075.

Intel documentation for Ubuntu 22.04 does list all runtime components
needed by the driver and oneAPI Cycles device but end-users getting
drivers from (other) sources can easily end-up missing required
Level-Zero Loader and struggle root causing what's wrong in their
system. Calling this requirement out in the UI will hopefull help them.
oneAPI Level-Zero incl. Loader: https://github.com/oneapi-src/level-zero
Common package names: level-zero, level-zero-loader
This fixes a 15% performance regression silently introduced by
79ab76e156 that aligned the compact
float3 on 16 bytes for oneAPI.
Current change is minimalist, there are further cleanup opportunities
such as removing packed_float3 definition for oneAPI but for some
reason, it cuts the recovered speedup in half, so we're starting with
this small fix for now.
