Using the new host_net_redir command you can easily create
redirections

While that's great, it's missing the removal of redirections, in
case you
want to have a port closed again at a later point in time.
This patch adds support for removal of redirections.
Cool. I was just too lazy to hack on slirp for this so far, but now
you
did it.

If going for a single command, this should rather look like this:
"[tcp|udp]:host-port:[guest-host]:guest-port |
remove [tcp|udp]:host-port"
BTW, I didn't refactor this interface along with the command line
changes, but I should actually. To remain consistent, we should
call it
host_net_fwd (-redir will be replaced with hostfwd=<rule>) or even
take
the chance and split it into host_net_fwd_add and
host_net_fwd_remove.
