I agree that atleast in Linux we should just remove the calls to change
recvbuf and sendbuf. Haven't tested in Windows how well Windows can tune
those itself to be proper.

Atleast for my testing HD udp/ts multicat stream drop packets here and
there with default code and removing recvbuf calls all together and use
os level stuff to tune buffers fix this.
