gossip_getnodes_entry was used by gossipd for reporting nodes, and for
reporting peers. But the local_features field is only available for peers,
and most other fields are only available from node_announcement.
Note that the connectd change actually means we get less information
about peers: gossipd used to do the node lookup for peers and include the
node_announcement information if it had it.
Since generate_wire.py can't create arrays-of-arrays, we add a 'struct
peer_features' to encapsulate the two feature arrays for each peer, and
for convenience we add it to lightningd/gossip_msg.

This patch guts gossipd of all peer-related functionality, and hands
all the peer-related requests to channeld instead.
gossipd now gets the final announcable addresses in its init msg, since
it doesn't handle socket binding any more.
lightningd now actually starts connectd, and activates it. The init
messages for both gossipd and connectd still contain redundant fields
which need cleaning up.
There are shims to handle the fact that connectd's wire messages are
still (mostly) gossipd messages.

connectd has a dedicated fd to gossipd, so it can ask for a new gossip_fd
for a peer.
gossipd has a standalone routine to create a remote peer (this will
eventually be the only way gossipd creates a new peer).
For now lightningd creates a socketpair but doesn't run connectd, so
gossipd never sees any requests on this fd.

This is just copying most of gossipd/gossip.c into connectd/connect.c.
It shares the same wire format as gossipd during transition, and changes
are deliberately minimal.
It also has an additional message 'connect_reconnected' which it sends
to the master daemon to tell it to kill a peer; gossipd relied on
closing the gossipfd to do this, but connectd doesn't maintain an fd
with remote peers.

This will avoid us having to round-trip to the HSM each time we want it.
For now we still derive it, too, and assert it's correct.

This means onchaind doesn't need the per-channel secret at all (aka. peer seed)
so we remove that from the onchaind_init message.

Really, we should have a 'struct point' since we don't use all points
as pubkeys. But this is the minimal fix to avoid type cast nastiness.

Removed `json_get_params`.
Also added json_tok_percent and json_tok_newaddr. Probably should
have been a separate PR but it was so easy.

This converts about 50% of all calls of `json_get_params` to `param`.

I crashed the HSMD, and it gave no output at all. That's because we
were only reading the status fd when we were waiting for a reply.
Fix this by using a separate request fd and status fd, which also means
that hsm_sync_read() is no longer required.

We need this later, to generate its seed. When we switch to lnd's key system,
we'll only need this, and not peerid.
Note also that the peerid is not just for messages any more, too.

- fixes problem with polling interval > 150 * 0.9
- fixes log message 'feerate hit floor' at every feerate change
- smoothed fee now reaches 90% of (exp weighted) fee estimates polled in last
120s, independent of polling interval
- only apply smoothing when effect > 10 percent so it doesn't correct forever
- fix indentation
This is a cosmetic change only. No functional changes.
I shortened the names of macros and changed param_parse() to param().
Also went through params.h with a fine-toothed comb and updated the comments
to reflect the current API.
I wanted to change the files:
params.c -> param.c
params.h -> param.h
run-params.c -> run->param.c
but that confused `git diff` for params.h so its best left for another PR.
I'm keeping #1682 updated locally with all these changes.

@wythe points out that many cases want a default value, not NULL.
Nicer to do it in the param_parse() call.

I'm not completely convinced that it's only ever set to a failcode
with the BADONION bit set, especially after the previous patches in
this series. Now that channeld can handle arbitrary failcodes passed
this way, simply rename it.
We add marshalling assertions that only one of failcode and failreason
is set, and we unmarshal an empty 'fail' to NULL (just the the
generated unmarshalling code does).

typesafe_cb isn't suitable here, as it is simply a conditional cast,
and the result is passed through '...' and doesn't matter.

json_listpeers returns an array of peers, and an array of nodes: the latter
is a subset of the former, and is used for printing alias/color information.
This changes it so there is a 1:1 correspondance between the peer information
and nodes, meaning no more O(n^2) search.
If there is no node_announce for a peer, we use a negative timestamp
(already used to indicate that the rest of the gossip_getnodes_entry
is not valid).
Other fixes:
1. Use get_node instead of iterating through the node map.
2. A node without addresses is perfectly valid: we have to use the timestamp
to see if the alias/color are set. Previously we wouldn't print that
if it didn't also advertize an address.

@rustyrussell showed we don't need temporary objects for params.
This means params no longer need a tal context.

@wythe points out we don't need to keep the around now param_is_set()
is removed. We can in fact go further and avoid marshalling them into
temporary objects at the caller altogether.
This means internally we have an array of struct param, rather than an
array of 'struct param *', which causes most of the noise in this
patch.
