Several users have noticed that they cannot pay satoshis.place or similar places
that have tiny payment amounts if they are not directly connected. This is due
to the forwarding fee dominating the transferred amount.
This commit adds a new option, exempting tiny fees (up to 5 satoshis by default)
from having to pass the maxfeepercent flag. While we could have told users to
tweak maxfeepercent I think it is usefull to have a default exemption.

Developer errors result in command_fail being called
just like other errors. The bad_programmer() Test is now updated
and passing.

They now just call command_fail() and cause param() to return false.
Temporarily disabled all the run-param.c tests that redirect
asserts so CI would still pass.

We use these for receiving arrays at init time, we should also use them
for fulfull/fail of HTLCs in normal operation. That we we benefit from all
those assertions.

The master tells us the short_channel_id of the outgoing channel when
failing an HTLC, but channeld didn't store it anywhere. It also
didn't tell channeld the short_channel_id in the case where we're
reconnecting and it's feeding us an array of failed htlcs.

We used to just manually set ROUTING_FLAGS_DISABLED, but that means we
then suppressed the real channel_update because we thought it was a
duplicate!
So use a local flag: set it for the channel when the peer disconnects,
and clear it when channeld sends a local update.

This needs to be done separately from the rest of the daemon since we can
otherwise not make sure that it happens before the DB is freed and we might
still need the DN, and be running in a DB transaction, for some destructors to
run.
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.

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

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.
