setting of window size should be explicit

Presently we set the window size to DEFAULT_TCP_BUFSIZE.

This has two issues:

1. it overrides the system default implicitly
2. it may prevent the system's auto tuning from working

Instead we should set socket_snd_bufsize and socket_rcv_bufsize to zero by default (probably in
iperf_defaults()). Then when it comes time to set the socket_snd_bufsize and socket_rcv_bufsize
only set it if it isn't zero.

for the present iperf the tool should use -w to set both socket_snd_bufsize and
socket_rcv_bufsize, but in the long term we probably want options to set the individually.
