Add a Rapid Commit option to Solicit messages and expect a Reply to be received instead of an Advertise. When receiving a DHCPv6 message from the server in state Solicit, continue testing whether the message is a Reply. Ease up the message type checking, it's not fatal if the message is of a wrong type. Add helper functions to set/get the rapid commit of a lease. See RFC 3315, sections 17., 17.1.2., 17.1.4. and 18.1.8.
