This is in preparation for the next step.
Note that we now don't add it to the linked list of txs we've send
until after it's sent by the immediate callback; this means it won't
get broadcast by the timer until after it's been done by broadcast_tx.
Also, this means we no longer steal the tx in broadcast_tx(); but we'll fix
up the leaks 4 patches later.

We don't simply parent them on the object, we use a dummy object which tells
us not to call the callback if freed.
This would be better fixed by rewriting ccan/io to handle tal_free() of
a conn; then we could simply parent the entire thing and forget about it.

This fixes half of #59 (the part which crashes). It doesn't fix the
fact that we should never be doing this for testnet.

Allocate the route off the current command, not dstate. And in the
case where the route is somehow not via a peer, don't leak memory.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Generally, the pattern is: everything returned is allocated off the return
value, which is the only thing allocated off the context. And it's always
freed.
Also, tal_free() returns NULL, so it's useful for one-line error
cleanups.

This shouldn't happen, but if our RNG is busted and get a duplicate,

`listinvoice` was not handling numeric labels correctly if they are not
passed in as JSON strings (which was the behavior of
`lightning-cli`). So now we accept both string labels as well as numeric
labels.
The JSON-RPC was non-standard compliant in that it omitted the required
`jsonrpc` entry and it was returning both `error` as well as
`result`. This fixes both of these issues.
Fixes#50. Was causing a segfault because it was creating an empty route
and was trying to extract the first hop as next hop. Routes through self
can still be created manually, but `sendpay` would still refuse to act
on them due to the missing self-link.
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.

Make this always the first packet after auth. That means there's no
reliance on whether a node remembers an aborted connection.
It also gives us a place to put version bits.

In particular, remove fee ranges on testnet (too unreliable) and accept

Firstly, we need to update the staging fee amount when we queue a change.
Secondly we need to remove completed fee updates, otherwise we hit a

We store peers in the database for STATE_INIT, but they don't reconnect

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.

getnodes returns an object containing a single array of 'nodes'. Each
element contains the node's ID, its hostname and its port. If
unknown (because we haven't seen a node announcement yet) then the port
is 0 and the hostname is null.
lightningd now uses a WHOIS query on itself to learn its external IP
address and announces that on the channel with the NODE message. It also
tracks other nodes in the routing table.
Refactored the signature verification to reuse it for both CHAN and NODE
messages.
'getchannels' returns a 'channels' array containing an object for each
known channel. Each channel object represents one direction of a
bidirectional channel, with a from and a to node ID along with the fees
for that direction. This matched the internal storage of channels and
allows unbalanced fees for each direction.
We *should* be in a state which accepts it (could happen with reorg),
and there's no reason to test for greater than depth since we must process
blocks in order.

Added channel announcement serialization and parsing, as well as the
entrypoints for the IRC peer discovery. Announcements are signed by the
sending endpoint and signatures are verified before adding the channels
to the local view of the topology. We do not yet verify the existence of
the anchor transaction.
It's not in a transaction in one caller, so wrap that.
This removes some more error handling code.
