Subject: [PATCH] avformat/hlsenc: add warning for append_list and
 hls_init_time option

When use append_list mode, the hls_init_time set nouse,
Because the append_list only support append at the old m3u8 end
cannot set init segments durations at the middle of the list.
That's invalid. and show a warning message for user.
