a4fdaab5b3 Use global secp256k1_ctx instead of passing it around.
If I'd known how large this patch would be (though trivial), I'd
have done it in parts.

71b8a07c56 db.c: database API.
These tables could use a rework, as they largely reflect our internal
state.  But it's a start.

0bb183e028 peer: split and expose new_peer function.
More of a pure allocator, for when we load peers from db.  Also moves
shachain_init out of secrets and into new_peer where it logically
belongs.

7709eb9b4a protocol: use separate ack packet.
It's a data-leak to send ack before we have verified identity of peer.
Plus, we can't send it until we know which peer it is, anyway!

364c2cd2c0 key_from_base58 / pubkey_from_privkey: don't support non-compressed keys.
It just clutters the API, and we don't support them on the wire anyway.

caf50c9ae4 peer: handle fulfull and fail onchain.
We now need to use bitcoin_witness_htlc with the r value, so that API
is updated to take 'struct rval' or 'struct sha256'.

We use the nc->delay amount (ie. dstate->config.min_htlc_expiry) to
wait for a timeout refund to be buried before "failing" upstream.
This should probably be made into a clearer parameter rather than
overloading this one.

Header from folded patch 'dont-use-peer-nc-in-onchain-code.patch':

peer: Don't use peer->nc->delay for onchain case.

Use the config var directly.  We should be freeing peer->nc when the
connection dies anyway.

5eb50345ae daemon: implement bitcoin_htlc_timeout()
This is called when an HTLC times out, and we need to send it back to
ourselves.  We also adjust the locktime, since in practice we should
refuse an HTLC less than our locktime.

bd081d219d protocol: anchor output is now witness 2of2.
Rather than p2sh of a 2of2, it's now a version 0 witness program.
This means that the commit transaction input and mutual close

862509637b daemon: implement unilateral commit.
This is only for the simple case where there are no HTLCs.

We group the current commit information together in the struct;
this involves a trivial transform from peer->cur_commit_theirsig to
peer->cur_commit.theirsig.
