38a0ee8638 jsonrpc: current pending commands are not a leak.
The pay command in particular, attaches a reasonable number of
temporaries to cmd, knowing they'll be freed once cmd is done.

ccb7047291 lightningd: add notleak annotations.
We have things which we don't keep a pointer to, but aren't leaks.
Some are simply eternal (eg. listening sockets), others cases are
io_conn tied to the lifetime of an fd, and timers which expire.

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.

78cd25d620 ipaddr: rename to wireaddr.
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.

bd1cac34ce netaddr: remove.
We use ipaddr everywhere now, so we can remove this.

3c6eec87e3 Add DEVELOPER flag, set by default.
This is a bit messier than I'd like, but we want to clearly remove all
dev code (not just have it uncalled), so we remove fields and functions
altogether rather than stub them out.  This means we put #ifdefs in callers
in some places, but at least it's explicit.

We still run tests, but only a subset, and we run with NO_VALGRIND under
Travis to avoid increasing test times too much.

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.

eac770760c jsonrpc: Make sure we handle the case where jcon outlives command
So far only happens during normal shutdown, but it may happen in other
cases as well. We simply define a new destructor that unregisters the
`cmd` from the `jcon`.

3564263e12 jsonrpc: use-after-free bug due to unspecified free behavior 1/2
These were fun to hunt down. The jcon and the conn are allocated off
of ld, so the free order is unspecified and if conn is freed before
conn then the finish_jcon destructor uses conn after free.

[ Edit: split commit, modified to use a destructor directly on jcon,
  which is more robust than relying on it only being freed via conn --RR ]

8375857116 common: absorb remaining files from daemon/
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).
