retransmittion by handover event (fast mobility code) - Fixed problem of mobility code which is caused by remaining parameters in the deleted primary destination. - Add a missing lock. When a peer sends an INIT, and while we are processing it to send an INIT-ACK the socket is closed, we did not hold a lock to keep the socket from going away. Add protection for this case. - Fix so that arwnd is alway uses the minimal rwnd if the user has set the socket buffer smaller. Found this when the test org decided to see what happens when you set in a rwnd of 10 bytes (which is not allowed per RFC .. 4k is minimum). - Fixes so a cookie-echo ootb will NOT cause an abort to be sent. This was happening in a MPI collision case. - Examined all panics and unless there was no recovery, moved any that were not already to INVARANTS. Approved by: re@freebsd.org (gnn)
