net/tstun: refactor peerConfig to allow storing more details

Browse Source

This refactors the peerConfig struct to allow storing more
details about a peer and not just the masq addresses. To be
used in a follow up change.

As a side effect, this also makes the DNAT logic on the inbound
packet stricter. Previously it would only match against the packets
dst IP, not it also takes the src IP into consideration. The beahvior
is at parity with the SNAT case.
