nbdrootd uses port reserved for sieve (Port 2000)

Really we should apply to IANA and get a valid well-known number for nbdroot and nbdswap
I'll take this on.

Since 4 Aug 2010 upstream nbd-server is using IANA assigned port 10809:
http://nbd.git.sourceforge.net/git/gitweb.cgi?p=nbd/nbd;a=commit;h=d208e07570e454ba421a3d7d5fcba393564a7b64

Maybe nbdrootd should use the same port since it "hides" the nbd-server through inetd stdio.

Also nbdswapd could be merged into nbdrootd and use the same port because now nbd supports named exports:
https://bugs.launchpad.net/ubuntu/+source/nbd/+bug/593227/comments/7

Commited support for nbdname= to ltsp-trunk and ldm-trunk.
The default for Oneiric is now to run nbd-server as a daemon instead of using inetd.conf

Current support is limited to root device, swap still uses inetd.conf (might be broken on Oneiric for the same reason nbdroot was).

This bug was fixed in the package ltsp - 5.2.12-0ubuntu1
