  vulkan: use a single command buffer per command buffer pool
  
  We violated the spec, which, despite the actual command buffer pool
  *not* being involved in any functions which require external synchronization
  of the pool, *require* external synchronization even if only the
  command buffers are used.
  
  This also has the effect of *significantly* speeding up execution
  in case command buffers are contended.

  avcodec/dvbsubenc: Sanity check num_rects
  
  It is written as region_id which is a single byte.
  Also fixes a potential (defined) overflow in the num_rects * 6
  multiplication later; this has been found by 김승호 <kimsho98@naver.com>.

• Revert "lavf/id3v2dec : support multiple values and TIPL frames"

  Revert "lavf/id3v2dec: support multiple values and TIPL frames"
  
  see: Re: [FFmpeg-devel] [PATCH 2/2] avformat/id3v2: Check that decode_str() did advance
  
  but in short, first our API since 16years says we dont have multiple values per key
  (which it supports since 9 years only)
  
  and it causes some problems for ffprobe apparently.
  I do believe the original patch is the correct direction but it requires
  more changes. So revert this until other things are in place and until
  we have a consensus.
  
  This reverts commit 80b77e8e8d0630710ad6069133f397459015f139.
