Justin Kim f78be9d698 srt: Introduce SRT source and sink
SRT[0] is an open source transport technology[1] that optimizes
streaming performance across unpredictable networks.

Although SRT is based on UDP, it works like connection-oriented
protocol. However, it doesn't mean that the SRT server or client
is necessarily to link to a receiver or a sender so, here, the
pairs of source and sink elements are introduced.

 - srtserversink: SRT server to feed SRT stream
 - srtclientsrc:  SRT client to get SRT stream from srtserversink

 - srtclientsink: SRT client to send SRT stream
 - srtserversrc:  SRT server to listen from srtclientsink
