3121015dceb1d269d79690c8f15c8e1406c9b09f as tests are failing.

Fix T78776: Cycles OpenCL error after recent changes for holdouts

Cleanup: minor refactoring in Cycles update detection code

Cleanup: reduce hardcoded numbers in denoising neighbor tiles code

Cycles: support OpenImageDenoise in final renders

Performance is not great currently due to the API not seeming to support
efficient denoising of multiple tiles at the same time. So in many cases
only one or a few threads will actually be denoising at the same time.

In renders with many samples this is not a big problem, but for faster
renders it's a signficant overhead.

We should try to optimize this still, possibly by batching denoising of
a bigger neighborhood of multiple tiles at once.

Fix T78775: broken Embree build in make deps for 2.83

The release was re-issued for unknown reasons, changes seems like they would
have no impact on Cycles and Embree is disabled by default anyway.

Build: add more libc compatibility functions for upcoming libraries update

These are needed by the x264 library.
