-Remark:
-(1) back source process: create by master process, get stream from 
-    upnode server if edge, create stream if origin, serve the stream 
-    process.
-(2) stream process: create by master process, get stream from back
-    source process, serve the client.
-(3) the embeded mininum http server, also provides vod service. for
-    http server, it provides http api, hls(live/vod) delivery. for
-    vod server, it slice the file to hls(m3u8/ts).
-Remark:
-(a) This multiple processes architecture is design by wenjie, it's a
-    very simple and powerful multiple process architecture, for the
-    master no need to pass between stream process.
-(b) The CLI architecture is similar to this, instead, cli process
-    will collect informations from all stream process, master process
-    only send signals to child processes.
-(c) Maybe multiple thread is ok? By winlin.
