Add support to read/write from disk

[GoogleCodeExporter]

Adding file I/O would allow iperf to check of the bottleneck was the network or 
the disk.

This should be for both the client and server, and should support /dev/zero and 
/dev/null as files,
and also maybe reading from stdin and writing to stdout too.

Looks like the "-F" flag is available for this.
