add support for "sendfile" call

[GoogleCodeExporter]

Adding a command line option to do splice/sendfile instead of sockets would be 
very useful.

Here are some links for more info:

Linux:  http://www.kernel.org/doc/man-pages/online/pages/man2/sendfile.2.html
FreeBSD: http://www.freebsd.org/cgi/man.cgi?query=sendfile&sektion=2
