Detailed Description

This class handles the p2p message MNAUTH.

MNAUTH is sent directly after VERACK and authenticates the sender as a masternode. It is only sent when the sender is actually a masternode.

MNAUTH signs a challenge that was previously sent via VERSION. The challenge is signed differently depending on the connection being an inbound or outbound connection, which avoids MITM of this form: node1 <- Eve -> node2 while still allowing: node1 -> Eve -> node2

This is fine as we only use this mechanism for DoS protection. It allows us to keep masternode connections open for a very long time without evicting the connections when inbound connection limits are hit (non-MNs will then be evicted).

If we ever want to add transfer of sensitive data, THIS AUTHENTICATION MECHANISM IS NOT ENOUGH!! We'd need to implement proper encryption for these connections first.
