   avformat: check avio_read() return values in dss/dtshd/mlv
   Multiple demuxers call avio_read() without checking its return
   value. When input is truncated, destination buffers remain
   uninitialized but are still used for offset calculations, memcmp,
   and metadata handling. This results in undefined behavior
   (detectable with Valgrind/MSan).
   
   Fix this by checking the return value of avio_read() in:
   - dss.c: dss_read_seek() — check before using header buffer
   - dtshddec.c: FILEINFO chunk — check before using value buffer
   - mlvdec.c: check_file_header() — check before memcmp on version
   
   Fixes: #21520
