[Serdev] Path support

[Greger V. Teigre]

Hi,
The path module in experimental was incomplete when Andreas Granig 
created a more complete patch. I believe the intention was to use Path 
headers together with usrloc-cl, thus enabling may registrars to save 
location to a common mysql db/cluster and easily route outgoing messages 
to the registrar/proxy being able to traverse the far-end NAT of a UA.

What is the status of this patch in Ottendorf?  I believe the patch was 
posted to the bugtracker, but I cannot find it?!
