Unidirectional transports and connections are now called
simplex rather than batch. Bidirectional transports and connections
are now called duplex rather than stream.

Ignore expected IVs that arrive by the wrong transport.

This prevents an attacker from replaying connections to test whether a
transport endpoint has the same owner as an endpoint on another
transport (eg probing a Bluetooth device to see whether it has the
same owner as a given internet host).
