Log Message:
Close item 69: buffer in-flight data during self-initiated rekey

The kexinit wait loop silently discarded non-KEXINIT messages received
between sending our KEXINIT and receiving the peer's.  RFC 4253 s7.1
restricts message types on the SENDER only; the peer may have valid
connection-layer messages in flight.  Added a rekey message queue that
buffers these messages and replays them through recv_packet() after
rekey completes.  Also fixed a latent bug where recv_packet's default
case set rekey_pending during an active rekey, which would have caused
nested rekey attempts with enough in-flight packets.
