Update version, adapt patch, correct PID writing, correct build on newer
FreeBSD releases, and most importantly introduce new patch to try to
avoid segfault caused by multiple network interfaces with the same (or
no) address. This is common when configuring bridges and tunnels.

 #   This allows us to unpack the tarball by just skipping the leading
 #   80KB (= 8192*10, see above).
