When receiving a live stream, ffserver hits 100% CPU usage because it 
busyloops while reading the non-blocking input socket. It should simply return 
from the read loop, to allow the poll loop to continue. With this patch 
ffserver's CPU usage drops from 100% to only 1% while receiving and 
broadcasting a stream.
