We used to have a `struct chan` while we're waiting for an update; now we
keep that internally. So a `struct chan` without a channel_announcement
in the store is private, and other is public.

We currently create a struct chan when we receive a `channel_announcement`,
but we can only broadcast once we have a `channel_update` (since that
provides the timestamp).
This means a `struct chan` can be in a weird state where it exists,
but is unusable (can't use without an update), and also means we need to
keep the channel_announcement message around until an update arrives, so
we can put it in the gossip_store.
Instead, keep track of these "unupdated" channels separately, and check
for them in all the places we search for a specific channel to update.

If we have a channel_announcement, we catch any node_announcement for
either end while we validate the channel_announcement. But if we have
multiple channel_announcements and the first one failed to verify, it
would remove this catch, meaning we'd discard following node_announcements
even though there was a pending channel_announcement.
The answer is to use a simple reference count, and as a further
optimization, only place the `pending_node_announce` if there's no
node already.
We also move the process_pending_node_announcement() calls lower down,
so *any* new channel creation checks it. This is more robust, and
will prove useful for the next patch, where we can use the same
mechanism to handle node_announcements on channel_announcements which
are verified, but don't yet have a channel_update.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
This is currently done higher up, in handle_channel_update(), but
that's one reason why handle_channel_update() has to do a channel
lookup. Moving the check down means handle_channel_update() can do a
minimal "get node id for this channel" so it can check the signature.
This helps, because the chan lookup semantics are changing in the next
few patches.

We used an s64 so we could use -1 and save a check, but that's just
silly as we have adjacent non-u64 fields: wastes 7 bytes per node
and 16 per channel.

now we print the subtypes out when you call printwire
note that we have to reverse the order the subtypes appear in
because
1) they're static and,
2) a few of them are nested
the original version of the subtype generator emitted '$'
to designate that a field was a subtype; now it's got a different
format:
funding_type,8,num_inputs,2
funding_type,10,input_info,num_inputs*input_info
this patch updates our generator to understand this new format
This is needed so that some csv's can expose their subtype parsing
functions in their header. This gets used in a later PR where
we start replacing manually created 'subtype' definitions with
generated ones.
Travis caught an error where this happened: when closingd reconnects it
was sending the reestablish message without the option_dataloss_protect
fields. That causes the peer to fail the channel!
