Rusty Russell c536616bee lightningd/lightningd: wire up lightningd_gossip.
Now we hand peers off to the gossip daemon, to do the INIT handshake and
re-transmit/receive gossip.  They may stay there forever if neither we nor
them wants to open a channel.

Rusty Russell 1800e84db7 subdaemon: callback to handle subdaemon status updates.
It's a bit messy, since some status messages are accompanied by an FD:
in this case, the handler returns STATUS_NEED_FD and we read that then
re-call the handler.

Rusty Russell 4b9eb19c68 status: don't send overlarge messages.
We'll assert if we try: better to truncate, trace a warning, and let the
recipient complain about a truncated message,

This is particularly an issue when we're sending encapsulated messages;
this avoids extra checks in the caller.

Rusty Russell a0ac5c276e status: API for status reporting.
The API formalizes how daemons should report their statuses back to
the main lightningd.  It's a simple write API, which includes tracing
support (currently it always sends traces, later it could send iff
there's a failure, for example).

Christian Decker bd6b9c377e coverage: Enable compilation with `--coverage`
Setting the environment variable `COVERAGE=1` allows us to turn
coverage measurements on. This produces a number of auxiliary gcno and
gcda files which can then be converted into coverage reports.

I know line coverage and branch coverage is not a perfect metric, but
it might get us some more visibility into where more tests might be
needed.

The recent update to BOLT #4 includes failure message specifications,

This lets us marshal and unmarshal undefined complex types; the fromwire

This turns out to be really nice for marshalling 'struct crypto_state'.
