Jindřich Makovička 1a8c6917f6 h264: avoid stuck buffer pointer in decode_nal_units 
When decode_nal_units() previously encountered a NAL_END_SEQUENCE,
and there are some junk bytes left in the input buffer, but no start codes,
buf_index gets stuck 3 bytes before the end of the buffer.

This can trigger an infinite loop in the caller code, eg. in
try_decode_trame(), as avcodec_decode_video() then keeps returning zeroes,
with 3 bytes of the input packet still available.

With this change, the remaining bytes are skipped so the whole packet gets
consumed.
