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. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
