Christian Decker 3cb576d69d refactor: Moving gossip/routing specific state into its own struct
This used to be part of `lightningd_state` which is being split up for
the various subdaemons. The main change is the addition of the `struct
routing_state` in `routing.h` and the addition of `rstate` in `struct
lightningd_state` for backwards compatibility.

Rusty Russell 6f360422d4 chaintopology: restore anchor timeout.
Instead of using wall-clock time, we use blocks.  This is simpler and

Rusty Russell b45b4eaba6 bitcoind: explicit flag to bitcoin-cli for testnet/regtest.
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.

Christian Decker 2a5a114f27 irc: Handle node announcements
lightningd now uses a WHOIS query on itself to learn its external IP

tracks other nodes in the routing table.

Refactored the signature verification to reuse it for both CHAN and NODE
messages.

Rusty Russell 012574790d pay: make interface idempotent.
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 makes more sense eventually: we may know the network addresses of

Rusty Russell 190b30e958 daemon: test restarting.
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.

Rusty Russell fa7934dfe3 htlc: implement deadline as per BOLT.
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.

Rusty Russell a3375516e5 daemon: don't ever use timeouts in seconds, always blocks,
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.

Rusty Russell 51de503096 daemon: keep track of simple addresses for injecting funds.
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!
