And divide fees as specified there.
We still use fixed values rather than floating, and we don't send or
handle update_fee messages.

We don't actually implement closing when we have HTLCs (we should
allow it, as that's what the clearing phase is for), since soon we'll
rewrite HTLC to match the async HTLC protocol of BOLT #2.
Note that this folds the close paths, using a simple check if we have
a close transaction. That's a slight state layer violation, but
reduces code duplication.

This means we send the first two revocation hashes; this is important
once we move to a commit model as we need to send (unsolicited) the
signature for the *next* commit tx so we need its commit hash.

This encapsulates proposals more cleanly, and is important when we change
the protocol to have more than one outstanding at a time.

The channel funding code needs to know who offered the anchor, as they
are responsible for paying fees until the other side is able to. This
is actually a hack, but at least now it's internal to funding and not
passed in at every funding_delta() call.

It currently points into freed memory once we've make_commit_txs; we
don't currently dereference it after that, but I did in some test code
and got a surprise. Make a copy in all cases where we set it, so
there can't be lifetime problems.

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.

We do the simplest thing: a timer goes off, and we check all HTLCs for
one which has expired more than 30 seconds ago.

This lets us implement accept_pkt_anchor().
Also had to predeclare sha256 in commit_tx.h, revealed by the new
includes.
