potentially be exploited. This commit contains several mitigations:

- Connections are no longer closed immediately on error, but put in

- The authentication protocol now requires a valid CHAL_REPLY from the
  initiator of a connection before sending a CHAL_REPLY of its own.
- Reduce the amount of connections per second accepted.
- Null ciphers or digests are no longer allowed in METAKEYs.
- Connections that claim to have the same name as the local node are
