qemu port update, kqemu

[Juergen Lock]

I have just tested kqemu (with Antony T Curtis' wrapper, thanx for that!)
and as it seems to work i added it to the port.  If anyone would like
to commit it, or just try it before its committed, the pr is at
http://www.freebsd.org/cgi/query-pr.cgi?pr=ports/80595
(fetch the raw pr if you would like to apply it to your ports tree.)

 And btw, kqemu is great! :)
