common: detect "sync error" from lnd.
I'm deeply reluctant to do this, as I'd thought this was fixed with
recent lnd versions. Logs below show that it continues, with channel
loss on almost every restart.
At this rate, we risk bifurcating the network. In fact, only four
errors my node have ever been NOT "sync error".

common/read_peer_msg: deconstruct into individual helper routines.
The One Big API is confusing, and has enough corner cases that we should

See: https://www.sandimetz.com/blog/2016/1/20/the-wrong-abstraction
In particular, when openingd is changed to chat to peers even when
it's not actively opening a channel, it wants to handle (most) errors
by continuing, not calling peer_failed().
This exposes the constituent parts.

gossipd: drain fd instead of passing around gossip index.
(This was sitting in my gossip-enchancement patch queue, but it simplifies
this set too, so I moved it here).
In 94711969f
we added an explicit gossip_index so when gossipd gets
peers back from other daemons, it knows what gossip it has sent (since
gossipd can send gossip after the other daemon is already complete).
This solution is insufficient for the more general case where gossipd
wants to send other messages reliably, so replace it with the other
solution: have gossipd drain the "gossip fd" which the daemon returns.
This turns out to be quite simple, and is probably how I should have
done it originally :(

status: split off error messages into a new 'peer_status' type.
Several daemons (onchaind, hsm) want to use the status messages, but
don't communicate with peers. The coming changes made them drag in
more code they didn't need, so instead we have a different
non-overlapping type.
We combine the status_received_errmsg and status_sent_errmsg
into a single status_peer_error, with the presence or not of the
'error_for_them' field indicating direction.
We also rename status_fatal_connection_lost() to
peer_failed_connection_lost() to fit in.

This change is really to allow us to have a --dev-fail-on-subdaemon-fail option
so we can handle failures from subdaemons generically.
It also neatens handling so we can have an explicit callback for "peer
did something wrong" (which matters if we want to close the channel in
that case).
