c3cbaf39bb hwcontext_vulkan: don't enable deprecated VK_KHR_sampler_ycbcr_conversion extension 
It was added to Vulkan 1.1 a long time ago.
Validation layer will warn if this is enabled.

3f65d24075 hwcontext_vulkan: fix user layers, add support for different debug modes 
The validation layer option only supported GPU-assisted validation.
This is mutually exclusive with shader debug printfs, so we need to
differentiate between the two.

This also fixes issues with user-given layers, and leaks in case of
errors.

869f4aec48 vulkan_decode: use the correct queue family for decoding ops 
In 680d969a30, the new API was
used to find a queue family for dispatch, but the found queue
family was not used for decoding, just for dispatching.

54754eec1e lavfi: add a new struct for private link properties 
Specifically those that should be visible to filters, but hidden from
API callers. Such properties are currently located at the end of the
public AVFilterLink struct, demarcated by a comment marking them as
private. However it is generally better to hide them explicitly, using
the same pattern already employed in avformat or avcodec.

The new struct is currently trivial, but will become more useful in
following commits.

80af195804 avcodec/vvcdec: move frame tab memset from the main thread to worker threads 
memset tables in the main thread can become a bottleneck for the decoder.
For example, if it takes 1% of the processing time for one core, the maximum achievable FPS will be 100.
Move the memeset to worker threads will fix the issue.

daf6fcd816 avcodec/vvcdec: do not zero frame qp table

For chroma, considering the joint CbCr, the QP tab size is related to the TU.

1f801dfdb5 lavc/libx265: unbreak build for X265_BUILD >= 210 
x265 added support for alpha starting with build 210.
While doing so, x265_encoder_encode() changed its fifth arg to
an array of pointers to x265_picture. This broke building lavc/libx265.c

This patch simply unbreaks the build and maintains existing single-layer
non-alpha encoding support.
