9c254c8387 gossipd: when we refresh channel, don't override pending updates.
We can have an update pending because it's too fast, but
refresh_local_channel is supposed to make sure we're up-to-date, so
force immediate application in that case.

Otherwise, we call update_local_channel at the bottom which frees the
pending update.  This can mean that we miss a change in fees, for example.

Changelog-Fixed: errors: Errors returning a `channel_update` no longer return an outdated one.

7e7ab4cb3b gossipd: remove routing, listchannels and listnodes infrastructure.
This involves removing some fields from the now-misnamed routing.h
datastructures, and various internal messages.

One non-obvious change is to our "keepalive" logic which refreshes
channels every 13 days: instead of using the 'enabled' flag on the
last channel broadcast to decide whether to refresh it, we use the
local connected status directly.

c34c055d82 Makefile: use completely separate spec-derived files for EXPERIMENTAL_FEATURES
This avoids overwriting the ones in git, and generally makes things neater.

We have convenience headers wire/peer_wire.h and wire/onion_wire.h to
avoid most #ifdefs: simply include those.

7f45e55d84 gossipd: set the push marker for our own messages.
This is a better fix than doing it manually, which turned out
to do it in the wrong order (node_announcement followed by
channel_announcement) anyway.

Should fix many "Bad gossip" messages.

ca53c1b699 gossipd: push our own gossip messages harder.
I had a report of a 0.7.2 user whose node hadn't appeared on 1ml.  Their
node_announcement wasn't visible to my node, either.

I suspect this is a consequence of recent version reducing the amount of
gossip they send, as well as large nodes increasingly turning off gossip
altogether from some peers (as we do).  We should ignore timestamp filters
for our own channels: the easiest way to do this is to push them out
directly from gossipd (other messages are sent via the store).

We change channeld to wrap the local channel_announcements: previously
we just handed it to gossipd as for any other gossip message we received
from our peer.  Now gossipd knows to push it out, as it's local.

This interferes with the logic in tests/test_misc.py::test_htlc_send_timeout
which expects the node_announcement message last, so we generalize
that too.

0091300ee3 gossipd: track what peer gave us gossip msgs so we can credit it.
Since we have to validate, there can be a delay (and peer might
vanish) between receiving the gossip and actually confirming it, hence
the use of softref.

We will use this information to check that the peers are making progress
as we start asking them for specific information.

This preempts the acceptance of
https://github.com/lightningnetwork/lightning-rfc/pull/666 but it's
clear that feature bits are going to be distinct, so this is safe to
do anyway.
