8a314e3f11 lavu/opt: Fix return of uninitialised value 
In one of the failure paths of av_opt_get_array, the ret variable
was accidentally declared again, shadowing the outer one and once when
jumping to the fail label would return the still uninitialised outer
one.

To fix this simply remove the local declaration of ret that shadowed
the outer one.

Introduced in d89930f866

Fixes: CID1618663 Uninitialized scalar variable

In one failure path for av_opt_set_array, the ret variable
was declared again, shadowing the outer one and writing the
return value to the wrong one and then after the goto returning
the uninitialized one instead.

3604b2403c swscale/rgb2rgb: improve chroma conversion in ff_rgb24toyv12_c 
The current code subsamples by dropping 3/4 pixels to calculate the
chroma components. This commit calculates the average of 4 rgb pixels
before calculating the chroma components, putting it in line with the
mmxext implementation.

6df0c5f9f4 lavc/vvc: Remove experimental flag 
This reverts commit 110d8549d5.

I have been working through fixing bugs, particularly crashes I've
found using a fuzzer, in the VVC decoder for the past few months.
While I won't claim it is now bug-free, it is considerably more
resilient than it was and I think in a position to have the
experimental flag removed for release 7.1.

Additionally, most of the Main 10 features of VVC which were missing
version of the decoder released in 7.0 have now been implemented.
This includes the most major missing features: IBC, subpictures and RPR.

672713761b lavc/hevcdec: move HEVCContext.sao_pixel_buffer_[vh] to HEVCLayerContext 
Handle them together with other sps-dependent arrays.

Note that current code only allocates these arrays when hwaccel is not
set, but this is wrong as the relevant code runs BEFORE get_format() is
called and hence before we know whether hwaccel is in use.

c7f0753a6b lavc/hevcdec: move active VPS from HEVCParamSets to HEVCContext 
Active VPS is a property of the decoding process, not of the list of
parameter sets.

Check that the VPS can only change in a base layer - while this can
never happen currently (as no other layers can exist in the decoder), it
will become useful when multilayer decoding is supported.
