Instead of reusing HSMFD_ECDH, we have an explicit channeld hsm fd,
which can do ECDH and will soon do channel announce signatures as well.

We *should* split the struct into key and data, rather than only comparing
the key parts in the htlc_end_eq function. But meanwhile, this fixes
the code.

This lets us link HTLCs from one peer to another; but for the moment it
simply means we can adjust balance when an HTLC is fulfilled.

This version correctly extracts fields with _ in them, meaning we get
more fields.
Also adds Makefile dependency which I noticed broke the build.

This is an approximate result (it's only our confirmed balance, not showing
outstanding HTLCs), but it gives an easy way to check HTLCs have been
resolved.

1) Need config.h before wire/gen_ are compiled.
2) The rule to checkout the libbase58 submodule doesn't work, so use the older
one-depends-on-the-other approach.

This just means we put the outgoing_cltv_value where we used to put zeroes.
The old daemon simply ignores this, but the new one should check it as per
BOLT 4.

If a peer dies, and then we get a reply, that can cause access after free.
The usual way to handle this is to make the request a child of the peer,
but in fact we still want to catch (and disard) it, so it's a little
more complex internally.

We call channel_sent_commit *before* sending (so we know if we need
to), so the name is wrong. Similarly channel_sent_revoke_and_ack.
We can usefully have them tell is if there is outstanding work to do,
too.

Passing through 'struct peer *' was a layering violation.

The three cases we care about only happen on specific transitions:
1. They can no longer spend our failed HTLC: we can fail the source now.
2. They are fully committed to their new HTLC htlc: we can forward now.
3. They can no longer timeout their fulfilled HTLC: the funds are ours.

Appending the channel direction ensures that the directions will be
treated independently. Without this only one direction would be
forwarded to the peers.
