f085a474b2 fix: Only add cli_args if we have some defined
This was causing calls to `bitcoin-cli` to fail on mainnet since it
was interpreting the empty string as the RPC method to call.

fbe3a017a9 gossip: Fix crash of getroute if we don't know any channels
This happens when we either have no channel open, or didn't announce
the channel. This patch just fails the getroute request. I'll later
add the non-broadcast announcement for local channels that should fix
this for unannounced channels.

2c0b52fb77 bitcoin: Make chainparams const
`cli` and `cli_args` were not `const` before since they are added to a
non-`const` array. Using `cast_const` we can keep them `const` without
unsafe cast.

3f65f0f000 lightningd: fix up malformed onion handling.
In the case where we can't decrypt the onion, we can't fail it in the
normal way (which is encrypted using the onion shared secret), we need
to respond with a update_fail_malformed_htlc message.

Moreover, we need to remember this for persistence.  This means that
we really have three conclusions for an HTLC: fulfilled, failed,
malformed.  Fix up the logic everywhere which assumed failed or
fulfilled.

05e951d748 wire: Correct the short channel id serialization to use 3+3+2
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.

b8ba8f003c logging: Removed automatic subprocess logging for bitcoind
This was responsible for a huge number of loglines simply because we
log every subprocess start and termination. Moving the logging
upstream to where it is really needed gets rid of the polling, that
are successful. A highly unscientific test shows a reduction in
loglines produced by lightningd from 17000 to 10000 lines.

2d76b066c2 routing: Cleaning up old hostname and port handling
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.

daf8866eb5 gossip: Implement the basic node_announcement
Rather a big commit, but I couldn't figure out how to split it
nicely. It introduces a new message from the channel to the master
signaling that the channel has been announced, so that the master can
take care of announcing the node itself. A provisorial announcement is
created and passed to the HSM, which signs it and passes it back to
the master. Finally the master injects it into gossipd which will take
care of broadcasting it.

b99c5620ef struct secret: use everywhere.
We alternated between using a sha256 and using a privkey, but there are

6a072c4c6e Fix a double-free bug in the negotiation phase
The callback on `key_negotiate` was closing the connection under
certain circumstances and would also `free` the key_negotiate, which
would then be freed again once it returns. We steal it off of the
connection during the callback and doing the free manually afterwards
to make sure this can't happen.

Thanks to @jgriffiths for tracking this one down.
