Rename the structs to match (and remove dev-echo).
This makes it clear that they're not the normal API.

This is less convenient to use, but makes far more sense for a real
user (like a wallet). It can ask about the route, then decide whether
to use it or not.
This will make even more sense once we add a parameter to control how
long we let the HTLC be delayed for, so a client can query for high,
medium and low tolerances and compare results.

We add a "dev-restart" command which causes the daemon to close fds
and exec itself. Then we do it after every command, with the caveat
that we always send a commit before newhtlc, because if not committed,
that is forgotten. Fulfillhtlc and failhtlc get resent, since they're
idempotent.

To do this we keep an order counter so we know how to retransmit. We
could simply keep old packets, but this is a little clearer for now.

This is the command an actual user would use: it figures out the fee
and route, and pays it if it can.

We're about to change the code so that if it can't route, it will fail
the HTLC. The current low-level tests will hate this, so have a dev switch
to turn that off.

A new 'accept-payment' command tells the node to fulfill HTLCs using
the R value if the amount is correct. It's not wired in yet.

We need to control the *inputs* to the anchor tx, to make sure they
pay to witness scripts (thus the anchor is immalleable). The easiest
way to do this is to hand out P2SH addresses for the user, and have
them pay into those. Then they hand us that tx and we use it to
create the anchor.
This is not a long-term solution!

We now keep a list of commitment transaction states for "us" and
"them", as well as a "struct channel_state" for staged changes.
We manipulate these structures as we send out packets, receive
packets, or receive acknowledgement of packets. In particular, we
update the other nodes' staging_cstate as we send out our requests,
and update our own staging_cstate are we receive acks. When we
receive a request, we update both (as we immediately send out our
ack).
The RPC output is changed; rather than expose the complexity, we
expose our last committed state: what would happen if we have to drop
to the blockchain now.
