P2P: Add option for Provision Discovery before GO Negotiation
This is a workaround for interoperability issues with some deployed P2P
implementations that require a Provision Discovery exchange to be used
before GO Negotiation. The new provdisc parameter for the p2p_connect
command can be used to request this behavior without having to run a
separate p2p_prov_disc command.
