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.

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!

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.

Uses a gcc extension (cast to union) for typechecking, but that can be
removed for compilers which don't support it.

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.

Rather than p2sh of a 2of2, it's now a version 0 witness program.
This means that the commit transaction input and mutual close
transaction input are both different.

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.
