  lavc/vvc: Skip enhancement layer NAL units
  
  The native VVC decoder does not yet support quality/spatial/multiview
  scalability.  Bitstreams requiring this feature could cause crashes.
  Patch fixes this by skipping NAL units which are not in the base layer,
  warning the user while doing so.

  avutil/frame: remove comment about avcodec_get_frame_class()
  
  The function was deprecated a while back and deleted last year.

  avcodec/ac3: Remove unused fixed-point ARMv7 DSP
  
  This diff removes 4 unused ARMv7 NEON fixed-point DSP functions.
  
  The function were originally moved here by 4958f35a2 (Dec 2013).
  
  After 9e05421db (Jan 2021), as part of the refactor of the AC3
  DSP to consistently use 32-bit sample format in the encoder, these
  functions were removed from the DSP function table, but the ARMv7
  implementations were kept.

  avcodec/x86/vvc/vvcdsp_init: add avg prototypes
  
  When we used the --disable-ssse3 --disable-optimizations options,
  the compiler would not skip the MC_LINKS like the compilation that
  enabled the optimization, so it would fail to find the function
  prototypes. Hence, this commit uses the same way to add prototypes
  for the functions as HEVC DSP.
  
  And, when prototypes are added for the functions, we cannot add the static qualifier.
  Therefore, the ff_vvc prefix is needed to avoid the naming conflict.
