Subject: [PATCH] Align the route message length to the next natural boundary
 via ALIGN() to ensure that the next message is nicely aligned as well. Some
 archs (sparc, m88k)have strict alignement issues since the inclusion of 64bit
 counters in the messages because those values could end up on non aligned
 addresses. Found and fix tested by miod@, OK deraadt@
