Implement session inactivity timeout

This timeout will prevent an attacker from using a session that has been
inactive for too long.
This inactivity timeout combined with the timeout before expiration makes a
good combination of security mechanisms to prevent session theft.

If no activity timeout is provided, then the feature is disabled and only
session expiration remains as a protection.
