This adds CONFIG_IP_NF_MMS: support for Microsoft Streaming Media 
Services. This allows client (Windows Media Player) and server
to negotiate protocol (UDP, TCP) and port for the media stream.

A partially reverse engineered protocol analysis is available 
from http://get.to/sdp, together with a link to a Linux client.

By default, the helper module tracks TCP traffic over port 1755
and adds the necessary UPD or TCP expectation. It is recommended 
to also open UDP port 1755 to the server, as this port is used 
for retransmission requests.

This helper has been tested in SNAT and DNAT setups.

Note that this helper has *nothing* to do with ip_masq_mms for 
2.2 kernels!
