openbgpd + 8.0

[Li, Qing]

I am not sure if what you are observing is a side effect of
svn-r196714. In particular, the code I added for:

--------------------
- Routing messages are not generated when adding and removing
  interface address aliases.
--------------------

If my memory serves me right, I put in the above patch for SCTP.
I'd be happy to work with you offline and confirm either way...
