  lavc/vvc: Fix derivation of inverse LMCS idx
  
  The clamping of idxYInv from H.266(V3) section 8.8.2.3 was missing.
  This could lead to OOB reads from lmcs->pivot or input_pivot.
  
  I also changed the derivation of the forward LMCS idx to use a shift
  rather than a division for speed and as this is actually how the
  variable is declared in the specification (8.7.5.2).

  avformat/dvdvideodec: fix seeking on multi-angle discs
  
  When seeking on multi-angle titles, libdvdnav does not lock on
  to the correct sectors initially as it seeks to find the right NAV packet.
  
  This manifests itself as two bugs:
  (1) When seeking on the first angle in a multi-angle segment,
  frames from another angle will appear (for example in intro
  or credits scenes). This issue is present in VLC also.
  
  (2) When seeking during a segment on angle n+1, the demuxer
  cannot deduce the right position from dvdnav and does not allow
  seeking within the segment (due to it maintaining a strict state).
  
  Correct the issue by switching to angle 1 before doing the seek
  operation, and skipping 3 VOBUs (NAV packet led segments) ahead
  where dvdnav will have positioned itself correctly.
