Hi all,

This is subset 3 of the larger RDS-TCP patch series I posted last
Oct.  The greater series aims to correct multiple rds-tcp issues that
can cause dropped or out of sequence messages.  I've broken it down into
smaller sets to make reviews more manageable.

In this set, we introduce extension headers for byte accounting
and fix several RDS/TCP protocol issues including message preservation
during connection transitions and multipath lane handling.

The entire set can be viewed in the rfc here:

Questions, comments, flames appreciated!
Thanks!
Allison
