Previously, the Blender video renderer did not have support for
encoding video to AV1 (not to be confused with the container AVI).
The proposed solution is to leverage the existing FFMpeg renderer
to encode to AV1.
Note that avcodec_find_encoder(AV_CODEC_ID_AV1) usually returns
"libaom-av1" which is the "reference implementation" for AV1 encoding
(the default for FFMpeg, and is slow). "libsvtav1" is faster and
preferred so there is extra handling when fetching the AV1 codec for
encoding such that "libsvtav1" is used when possible.
This commit should only affect the options available for video
rendering, which includes the additional AV1 codec to choose from, and
setting "-crf".
Also note that the current release of FFMpeg for ArchLinux does not
support "-crf" for "libsvtav1", but the equivalent option "-qp" is
supported and used as a fallback when "libsvtav1" is used (as
mentioned here: https://trac.ffmpeg.org/wiki/Encode/AV1#SVT-AV1 ).
(Actually, both "-crf" and "-qp" is specified with the same value in
the code. When a release of FFMpeg obtains support for "-crf" for
"libsvtav1" is released, the code shouldn't be needed to change.)
The usage of the AV1 codec should be very similar to the usage of the
H264 codec, but is limited to the "mp4" and "mkv" containers.
This patch pertains to the "VFX & Video" module, as its main purpose
is to supplement the Video Sequencer tool with the additional AV1
codec for encoded video output.

When the image colorspace is not data, linear or sRGB, the image will
be converted to float (and colorspace-converted) during loading.
However, if it also needs to be rescaled (due to exceeding the GPU
texture size limit), the resizing assumed that it's still a byte
texture.

This is to help ensure buildbot builds are correct, while still gracefully
disabling features in user/developer builds.
* Add WITH_STRICT_BUILD_OPTIONS to give an error when features can't be
enabled due to missing libraries or other reasons. Add new macro
set_and_warn_library_found used everywhere features were being
automatically disabled.
* Remove code from Windows and macOS for various libraries that would
automatically disable features. set_and_warn_library_found could be
used here also, but we are generally assuming the precompiled libraries
are complete and only test for availability when libraries are just
added.

It has not actually been enabled there for a long time in official releases,

The issue we ran into a lot is we have a python script that updates
git+SVN. Which works fine most of the time, except when we have a
python update in SVN, or worse a python version change. Python really
doesn't enjoy having its files being deleted or changed while it is
running and users generally end up with a corrupted lib folder.
This change updates the library folder using svn.exe first before
letting the python script run sidestepping the issue in most cases.
The python script will still run and do the more elaborate work
like updating git and switching SVN branches which could still
run into issues cause python still doesn't like being changed
while running but there's not a whole lot we can about that,
for *most* people however things will just work now.

Buildbot infrastructure relies on the fact that it can enable and
disable `WITH_CYCLES_<COMPUTE>_BINARIES` without affecting speed of
incremental builds. This allows buildbot to skip GPU kernels when
doing CI regression tests which do not need GPU kernels, as well as
it allows to move GPU kernels compilation to a separate step where
all the resources are available to the GPU kernel builders.
For the oneAPI compute enabling and disabling AoT kernels has much
higher implications due to the kernels being a part of the device
implementation from the build target perspective.
This change makes it so different target names are used for JIT and
AoT configurations, which allows CMake to more fully benefit from
"caching" the compiled result.
The end goal of this change is to make it so sequential build of the
same code base on the buildbot happens super fast,
Blender binary still needs to be re-linked when the AOT of oneAPI
option is toggled, but that's already the case in the buildbot due
to the WITH_BUILDINFO.

In rBed6c8d82b804 it was wrongly assumed that the constraint functions
always apply the transformations.
But that is not the case for when axes are aligned.
The `mul_m3_v3(t->con.pmtx, out)` fallback is still required.

The bokeh blur node flipped its bokeh input due to the conceptual
difference between the search window space and the weights texture
space. This patches fixes that by inverting the weights texture to match
the search window.
The variable size option actually flips the bokeh input for the CPU
compositor. It is unclear if this is expected, so we deviate from that
behavior for now.

- postfix the libraries with _d for debug

Adds the possibility of having a little number on top of icons.
At the moment this is used for:
* Outliner
* Node Editor bread-crumb
* Node Group node header
For the outliner there is almost no functional change. It is mostly a refactor
to handle the indicators as part of the icon shader instead of the outliner
draw code. (note that this was already recently changed in a5d3b648e3e2).
The difference is that now we use rounded border rectangle instead of
circles, and we can go up to 999 elements.
So for the outliner this shows the number of collapsed elements of a
certain type (e.g., mesh objects inside a collapsed collection).
For the node editors is being used to show the use count for the data-block.
This is important for the node editor, so users know whether the node-group
they are editing (or are about to edit) is used elsewhere. This is
particularly important when the Node Options are hidden, which is the
default for node groups appended from the asset libraries.
---
Note: This can be easily enabled for ID templates which can then be part
of T84669. It just need to call UI_but_icon_indicator_number_set in the
function template_add_button_search_menu.

Special thanks Clément Foucault for the help figuring out the shader,
Julian Eisel for the help navigating the UI code, and Pablo Vazquez for
the collaboration in this design solution.

With {D15885} this isn't useful as when disabled the view_layer

locating the source bases, then duplicate and sync and locate

This patch removes the resync forbid and improve the times

This patch implements the tone map node for the realtime compositor
based on the two papers:
Reinhard, Erik, et al. "Photographic tone reproduction for digital
images." Proceedings of the 29th annual conference on Computer graphics
and interactive techniques. 2002.
Reinhard, Erik, and Kate Devlin. "Dynamic range reduction inspired by
photoreceptor physiology." IEEE transactions on visualization and
computer graphics 11.1 (2005): 13-24.
The original implementation should be revisited later due to apparent
incompatibilities with the reference papers, which makes the operation
less useful.

THis is bumping dependencies to fix known CVEs, with the exception of
OpenImageIO which also includes bugfixes for performance and correctness
with some image types.
zlib 1.2.12 -> 1.2.13
freetype 2.11.1 -> 2.12.1
openimageio 2.3.13.0 -> 2.3.20.0
python 3.10.2 -> 3.10.8
openjpeg 2.4.0 -> 2.5.0
ffmpeg 5.0 -> 5.1.2
sndfile 1.0.28 -> 1.1.0
xml2 2.9.10 -> 2.10.3
expat 2.4.4 -> 2.4.9
openssl 1.1.1g/i -> 1.1.1q
sqlite 3.31.1 -> 3.37.2
Notable changes:
* AOM: the hack we had in place to make it not detect pthreads on windows no
longer worked with a more recent cmake version. Disabled pthreads with a
diff on Windows.
* Python: embedded copy of zlib 2.1.12 swapped out for our 2.1.13 copy with
some folder manipulation on Windows.
* Freetype: was harbouring a copy of zlib 2.1.12 as well, so that had to end.
* FFmpeg: patch used to fix D11796 is no longer needed. Add new patch to deal
with simple_idct.asm generating an object file with no sections in it,
backport from upstream commit.
* TinyXML: still being downloaded but no longer used by OpenColorIO, removed.
* GMP applied upstream patch to fix CVE-2021-43618, as there is no release yet.
* SQLite and Libsndfile patches no longer needed.
