We're going to wean off IRC, but as a quick fix, only announce 0-60 seconds
after we see a join, or every 6 hours.

In particular, remove fee ranges on testnet (too unreliable) and accept
a single confirm.
(Note that an earlier version of this had a bug when there was no
config file, this version includes the fix).

Three days of on and off debugging, before I realized my server was talking
to a non-testnet bitcoind. There was a bitcoind on that machine running
on testnet, but it uses the same dir and config, so the --bitcoin-datadir
option couldn't help.
This is more certain: specify whether we're testnet on every single query.
Now we can skip the attempt to parse bitcoin.conf, too.

We need some ordering to deliver them to the JSON "waitinvoice" command;
we use a counter where 0 means "unpaid".
We keep two lists now, one for unpaid and one for paid invoices.

We stopped automatically retransmitting locally-generated add/removes
after a reconnect, but this breaks the "pay" interface as it stands.
The correct solution to this is to make the pay interface idempotent:
you can trigger it as many times as you want and it will only succeed
once.

This allows hardcoded routes in the config file, which is required until
we get route advertisements.

This makes more sense eventually: we may know the network addresses of
many peers, not just those we're connecting to. So keep a mapping, and
update it when we successfully connect outwards.

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 avoids us having to query it when we create anchor transaction, and
lets us always use dynamic fee information.
The config options for max and min are now percentages, rather than absolute.

Thus a node MUST estimate the deadline for successful redemption for
each HTLC it offers. A node MUST NOT offer a HTLC after this
deadline, and MUST fail the connection if an HTLC which it offered is
in either node's current commitment transaction past this deadline.

If a block triggers two peers to close, we ran io_break() on both of them; the
second overrode the first and we didn't end up freeing that one.
Rather than chase such bugs in future, simply iterate to see if any
peers need freeing.

Note that the base fee is in millisatoshi, the proportional fee is
in microsatoshi per satoshi. ie. 1,000,000 means charge 1 satoshi for
every satoshi carried.

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.

The protocol still supports both, but we now only support blocks.
It's hard to do risk management with timeouts in seconds, given block
variance. This is also signficantly simpler, as HTLC timeouts are
always fired in response to blocks, not wall-clock times.

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.

While useful for testing, it doesn't make sense to have an explicit commit
command; we should commit whenever there are outstanding changes.
We have a 10ms timer to allow limited batching, however.

Rather than polling for interesting bitcoin txs via importaddress, we use

This allows us to track precise transaction depth ourselves,

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!

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.

When a peer is finally to be freed (ie. STATE_CLOSED), doing this
inside the state logic is a bit fraught. We're better off exiting the
io loop and freeing it there.

bitcoind has a limit of 16 requests at once, by default, so our simplest
solution is to serialize them.

Because we use the bitcoin wallet to create the anchor transaction, we
need to make sure it doesn't broadcast it; safest to check their config
for the option.
