dns: don't allow non-stream sockets.

It was "connecting" to "localhost 30000" successfully, because it was
using UDP. Oops.
This reveals another issue: init_conn() uses the wrong address to
connect to, as we'd already incremented the pointer in try_connect_one().

74f294e36c
daemon: encrypted communication (version 3)
...
After useful feedback from Anthony Towns and Mats Jerratsch (of
thunder.network fame), this is the third version of inter-node crypto.
1) First, each side sends a 33-byte session pubkey. This is a
bitcoin-style compressed EC key, unique for each session.
2) ECDH is used to derive a shared secret. From this we generate
the following transmission encoding parameters for each side:
Session AES-128 key: SHA256(shared-secret || my-sessionpubkey || 0)
Session HMAC key: SHA256(shared-secret || my-sessionpubkey || 1)
IV for AES: SHA256(shared-secret || my-sessionpubkey || 2)
3) All packets from then on are encrypted of form:
/* HMAC, covering totlen and data */
struct sha256 hmac;
/* Total data transmitted (including this). */
le64 totlen;
/* Encrypted contents, rounded up to 16 byte boundary. */
u8 data[];
4) The first packet is an Authenticate protobuf, containing this node's
pubkey, and a bitcoin-style EC signature of the other side's session
pubkey.
5) Unknown protobuf fields are handled in the protocol as follows
(including in the initial Authenticate packet):
1) Odd numbered fields are optional, and backwards compatible.
2) Even numbered fields are required; abort if you get one.
Currently both sides just send an error packet "hello" after the
handshake, and make sure they receive the same.
