Added an initiator flag (bit 31) to the IV.

Browse Source 
The flag is used to distinguish between the initiator and responder
directions of a stream-mode connection, allowing them to use the same
connection number without risking IV reuse.

The flag is also raised for batch-mode connections, which only have
one direction.
