Commit a57a2dcb86 introduced a time_t
in routing.h. So also move the time.h include to the header. This
fixes the build on FreeBSD.

We were dropping these on the floor while checking for txout. So now
we add a map that holds announcements while we are checking.

This is done it two parts, since we have to ask the main daemon to do
the lookup for us.
If this becomes a bottleneck, we can have a separate daemon, or even
an RPC pipe to bitcoind ourselves.

It's just a sha256_double, but importantly when we convert it to a
string (in type_to_string, which is used in logging) we use
bitcoin_blkid_to_hex() so it's reversed as people expect.

We can't get them; channel_update doesn't support it.

This will later be used to determine whether or not we should announce
ourselves as a node.

In future it will have TOR support, so the name will be awkward.
We collect the to/fromwire functions in common/wireaddr.c, and the
parsing functions in lightningd/netaddress.c.

1. The code to skip over padding didn't take into account max.
2. It also didn't use symbolic names.
3. We are not supposed to fail on unknown addresses, just stop parsing.
4. We don't use the read_ip/write_ip code, so get rid of it.

I missed these when I removed the legacy daemon. We also remove the
min_blocks field which was always 0.

Use a negative timestamp as the flag for this, making the test simple.
This allows valgrind to detect that we're accessing them prematurely,
including across the wire on gossip_getchannels_entry.

Some fields were redundant, some are simply moved into 'struct lightningd'.
All routines updated to hand 'struct lightningd *ld' now.

Also, we split the more sophisticated json_add helpers to avoid pulling in
everything into lightning-cli, and unify the routines to print struct
short_channel_id (it's ':', not '/' too).

"BOLT 7: add chain_hashes values to channel_update and channel_announcment"
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Fixes the `short_channel_id` being serialized as 4 bytes block height,
3 bytes transaction index and 1 byte output number, to use 3+3+2 as
the spec says.
The reordering in the unit test structs is mainly to be able to still
use `eq_upto` for tests.
The single string-based hostname and port has been retired in favor of
having multiple `struct ipaddr`s from the `node_announcement`. This
breaks the hostnames and ports from IRC, but I didn't bother to
backport ipaddr for it since it is only used in the legacy daemon.
The new onion uses the `channel_id` instead of the `node_id` of the
next hop to identify where to forward the payment. So we return the
exact channel chosen by the routing algo, to avoid having to look it
up again later.
The direction bit was computed in several spots and was inconsistent
in some cases. Now we compute it just in routing, and once when
starting up `channeld`, this avoids recomputing it all over the place.
Before exiting, `channeld` constructs and sends a `channel_update`
marking the channel as disabled. This is the pro-active signalling
that the channel may no longer be used.
The JSON-RPC call `getroute` and the functionality to compute the
actual route have been split so that we can reuse it independently of
the JSON-interface. Since this is now a routing-only method I also
moved it into `routing.[ch]` instead of `pay.c`.
The spec 4af8e1841151f0c6e8151979d6c89d11839b2f65 uses a 32-byte 'channel-id'
field, not to be confused with the 8-byte short ID used by gossip. Rename
appropriately, and update to the new handshake protocol.

Moved the broadcast functionality to broadcast.[ch]. So far this
includes only the enqueuing side of broadcasts, the dequeuing and
actual push to the peer is daemon dependent. This also adds the
broadcast_state to the routing_state and the last broadcast index to
the peer for the legacy daemon.
This was the only time we actually reference non-routing structs in
routing, so moving this out should allow us to get it working in the
new subdaemons.
This allows us to move some legacy functions closer to where they are
actually used, and not worry about them when including routing.h into
the new subdaemons. `struct peer` is the main culprit here.
