Please note this is an experimental module.  It works for me.  It may work
for you, it may panic your kernel, or it may just sit there using ram.

Features:

 * Detects STUN and stays out of the way.
 * Understands proposed client_port=3DM/N syntax.
 * There is a configurable policy for the destination parameter.

TODO:

 * Handle multiple SETUP messages in a single packet.
 * Un-mangle client_port on return trip.
 * IPv6 modules
 * Much more...

This should work with 2.4.20 and all of 2.4.21-pre# series up to and
including pre7, at least.  It should not work with 2.4.19 or prior.  I am
making _no_ attempt to do p-o-m or non-kernel iptables support.  Others may
feel free if they wish (hey, it's GPL).

The diff was prepared against 2.4.21-pre6.  Please use the "-p1" option to
patch(1) for proper application:

        # cd linux-2.4.21-pre7
        # cat ../nf-rtsp.diff | patch -p1

Comments (especially bug reports and success reports) welcome.

Hints about IPv6 conntrack and nat modules very appreciated (why is there no
IRC or FTP modules for IPv6?)
