5d0450461f idcin: better error handling 
Add some additional checks for EOF and print error messages on an incomplete
header or packet.

FATE reference updated for id-cin-video due to the demuxer no longer
returning a partial video packet at EOF.

71194ef6a8 rtpdec_vp8: Mark broken packets with AV_PKT_FLAG_CORRUPT 
This allows the caller to either include them (and get more packets
decoded, but possibly some nonperfect frames), or discard them (by
setting fflags=discardcorrupt).
