Cycles supports OptiX on Maxwell and up architectures, but the
default in OSL is to generate PTX targeting Pascal and up. Adjust the
OSL target architecture to Maxwell to fix this.

Multiple of our libraries would pull in system libraries that we have static versions of.
These where libxml2 and libz and also libzstd.
I also noticed that the script that was supposed to check on this was not really usable to check for these kinds of things so I updated it.
Now you can run it with `python3.11 tools/check_blender_release/check_release.py -- ../build_linux_release/bin/` and it will check all binaries and libraries that we ship for any system libraries that we don't expect to be linked.
The libraries I'm aware of that pulled in system libs were:
boost
mesa
osl
llvm
(The removed cmake flags for osl was because these were unused and cmake printed warnings)

Turns out we were not building OSL with OptiX enabled anymore.
Also check now if the OSL builds has OptiX support and if not
disable it in Cycles.
Building OSL with support for this (still) does not require
either the OptiX SDK or CUDA, it only needs LLVM.

Listing the "Blender Foundation" as copyright holder implied the Blender
Foundation holds copyright to files which may include work from many
developers.
While keeping copyright on headers makes sense for isolated libraries,
Blender's own code may be refactored or moved between files in a way
that makes the per file copyright holders less meaningful.
Copyright references to the "Blender Foundation" have been replaced with
"Blender Authors", with the exception of `./extern/` since these this
contains libraries which are more isolated, any changed to license
headers there can be handled on a case-by-case basis.
Some directories in `./intern/` have also been excluded:
- `./intern/cycles/` it's own `AUTHORS` file is planned.
- `./intern/opensubdiv/`.
An "AUTHORS" file has been added, using the chromium projects authors
file as a template.

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.

Pass `-DLINKSTATIC=ON` to the OSL CMake, to ensure it statically links to
our libpng. Previously this was only applied on Windows, it's now on all
platforms.
This diff somewhat snowballed out of updating OIDN to 1.4.1 it had some
changes that allowed us to remove the arm hacks we had in place and
revert to using identical versions for a whole bunch of deps. But that
required an update to ISPC which needed a newer LLVM and if we're
updating LLVM we may as well update OSL, and when we update OSL, OIIO
may as well be dragged in soo......anyhow...
This diff updates:
LLVM 9.0.0 (11.0.1 for mac/arm) -> 12.0.0
OIIO 2.1.15.0 -> 2.2.15.1
OSL 1.11.10.0 -> 1.11.14.1
winflex_bison 2.5.5-> 2.5.24 (ispc needed newer bison, windows only dep)
OIDN 1.4.0 -> 1.4.1
ISPC v1.14.1(random hash for mac/arm) -> v1.16.0
Flex 2.6.4 (ISPC needed newer Flex than available on CentOS 7)
and removes most of the "special arm/mac" versions. I think just ssl and
embree are left with special versions.
notable changes:
@LazyDodo included some clang headers in the linux/mac harvest which are
needed to start writing custom clang based tooling like D9465 these were
already shipping on windows, but not the other platforms.
[macOS] Change the `LC_ID_DYLIB` of OpenMP for {D11997}. This changes

Allow downloading of source packages of Blender's dependencies, so that
it's easier to provide a "full source archive" that contains the blender
source + all dependencies archives. A `make` command for this will be
introduced soon.
This changes the deps builder slightly to be more flexible with the
origin of our source packages.
To support this a new CMake variable has been added called `PACKAGE_DIR`
where all sources archives will be stored.
default: a directory called `packages` in the build folder.
alternative-default: if a directory called `packages` exists in the
blender source folder that will be used. This is to support the "full
source archive" use case.
The download phase have been moved from the build phase to the configure
phase. Configure will download all sources validate the hashes while
downloading.
All `[depname].cmake` files have been changed to take a local
`file://[path_to_local_tarball]` path rather than a remote URI.
A second requirement was that there needed to be an option to grab the
sources from the blender SVN mirror rather than upstream. For this an
option has been added PACKAGE_USE_UPSTREAM_SOURCES (default ON). The
exact location in SVN still needs to be worked out, I tested with my
local webserver and codewise it checks out. The path that is in there
currently will not work (given there is no mirror there yet).
To build this mirror our local package caches can be used.

This bumps OSL to 1.11.10.0. OSL Has a new build time
dependency: Clang, and more importantly it expects
clang and llvm to share a library folder, which it
previously for us did not.
This patch changes:
-OSL Update to 1.11.10.0
-refactor the llvm/clang/clang-tools-extra builds into the llvm
build using the llvm-project tarball for building that has all
of the subprojects in it.
-update ispc/openmp builds since clang no longer its own dependency
and they have to depend on the llvm build now.
-Update the windows builder to use the 64 bit host tools since it
ran out of ram linking clang
-Since OSL now needs clang to link successfully a findclang.cmake
has been provided for linux/OSX

This separates out PugiXML that was previously
bundled by OIIO.
As this linux/mac libs are not available
this commit only contains the builder and windows
changes, and the option to enable pugixml is
guarded by a platform if, this can be removed
once all platforms have committed the svn libs.
For details see D8628
When there is no system python OSL will fail to build the documentation.
Given we don't ship the documentation, this is safe to disable.

This aligns with the VFX reference platform 2020 along with the decision
to stick to Python 3.7, see T68774.
Blosc was downgraded to 1.5 as recommended by the OpenVDB documentation.
IlmBase and OpenEXR are now built together with CMake rather separately

This time both full `make deps` and final compilation is tested on
a freshly installed CentOS 7.
The thing is: OpenImageIO is not configured to use an external PugiXML
library, so it was compiling its own.
At the same time the OpenShadingLanguage library was commanded to use
an externally compiled PugiXML. This caused some sort of discrepancy
which lead to Blender-link-time errors. Could be linking error, could
be namespace related, could be ABI related. In any case since we do
have PugiXML in the OpenImageIO already lets just stick to it.
Now, things are becoming REALLY confusing. The script does build
pugi, but is never telling OIIO to use an external one. Which makes
it to use a bundled one.
Trying to link OSL to a different version of pugi causes a lot of
linking errors.
Interestingly enough, that was me who made OSL to use external pugi
to solve configuration problem. But now i can not reproduce that
anymore.
Ideally we would either link everything against our pugi, or not
compile it at all.
Mainly this is following Linux to build own xml2/lzma/ssl/sqlite and linking
them all statically. This ensures the Python ssl module uses a recent openssl
version rather than a very old one shipped with macOS.
there is an issue with objects destructing in a non deterministic way during process shutdown, temporary work around this until osl has a fix in place.
