[FIXBUG] [1] modify vlc httplive.c relative_URI method
		 [2] faplayer will try httplive first as stream filter, then use ts.c as demuxer
			 but sometimes this will cause A/V no sync(like CNTV)
		 [3] sohu TV, httplive will try failed, so use avformat as access_demux
		 [4] TODO all the two method httplive & ffmpeg can not play LETV
set httplive's module priority 0, not use it in hls
[hls]add hls note
