a52d522525 gossipd: handle ping messages for remote peers too.
This simplifies our ping handling: make gossipd always do it.

b876c601a6 Modern param style for chaintopology.c, ...
connect_control.c, dev_ping.c, gossip_control.c, invoice.c.

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

After trying (and failing) to squash and rebase #1682 I just made a new branch
from a patch file and closed #1682.

7f437715d5 Added error code parameter to command_fail
Until now, `command_fail()` reported an error code of -1 for all uses.
This PR adds an `int code` parameter to `command_fail()`, requiring the
caller to explicitly include the error code.

This is part of #1464.

The majority of the calls are used during parameter validation and
their error code is now JSONRPC2_INVALID_PARAMS.

The rest of the calls report an error code of LIGHTNINGD, which I defined to
-1 in `jsonrpc_errors.h`.  The intention here is that as we improve our error
reporting, all occurenaces of LIGHTNINGD will go away and we can eventually
remove it.

I also converted calls to `command_fail_detailed()` that took a `NULL` `data`
parameter to use the new `command_fail()`.

The only difference from an end user perspecive is that bad input errors that
used to be -1 will now be -32602 (JSONRPC2_INVALID_PARAMS).

e92b710406 tools/generate-wire.py: remove length argument from fromwire_ routines.
We always hand in "NULL" (which means use tal_len on the msg), except
for two places which do that manually for no good reason.

32411de90e lightningd: split struct peer into struct peer and struct channel.
Much like the database; peer contains id, address, channel contains
per-channel information.  Where we create a channel, we always create
the peer too.

For the moment, peer->log and channel->log coexist side-by-side, to
reduce some of the churn.

Note that this changes the API to dev-forget-channel: if we have more
than one channel, we insist they specify the short-channel-id.

91a22dc496 jsonprc: make json_get_params() fail the command, for better error reporting.
We move it into jsonrpc where it belongs, and make it fail the command.
This means it can tell us exactly what was wrong.

8c665835fa jsonrpc: make explicit call to indicate cmd is still pending.
jsonrpc handlers usually directly call command_success or
command_fail; not doing that implies they're waiting for something
async.

Put an explicit call (currently a noop) there, and add debugging
checks to make sure it's used.

474887512d gossipd: rewrite to do the handshake internally.
Now the flow is much simpler from a lightningd POV:

1. If we want to connect to a peer, just send gossipd `gossipctl_reach_peer`.
2. Every new peer, gossipd hands up to lightningd, with global/local features
   and the peer fd and a gossip fd using `gossip_peer_connected`
3. If lightningd doesn't want it, it just hands the peerfd and global/local
   features back to gossipd using `gossipctl_handle_peer`
4. If a peer sends a non-gossip msg (eg `open_channel`) the gossipd sends
   it up using `gossip_peer_nongossip`.
5. If lightningd wants to fund a channel, it simply calls `release_channel`.

Notes:
* There's no more "unique_id": we use the peer id.
* For the moment, we don't ask gossipd when we're told to list peers, so
  connected peers without a channel don't appear in the JSON getpeers API.
* We add a `gossipctl_peer_addrhint` for the moment, so you can connect to
  a specific ip/port, but using other sources is a TODO.
* We now (correctly) only give up on reaching a peer after we exchange init
  messages, which changes the test_disconnect case.

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).

85ff95e829 common: new directory for any shared objects.
To avoid everything pulling in HTLCs stuff to the opening daemon, we
split the channel and commit_tx routines into initial_channel and
initial_commit_tx (no HTLC support) and move full HTLC supporting versions
into channeld.

f24aab1916 sphinx: Updating daemon to new sphinx implementation
Mainly switching from the old include to the new include and adjusting
the actual size of the onion packet. It also moves `channel.c` to use
`struct hop_data`.

It introduces a dummy next hop in `channel.c` that will be replaced in
the next commit.
