Rusty Russell f2a4bd6ad8 wire: import new onion message spec.
One change from the obsolete version handling, gossipd will no longer send
forwarding onion msgs to lightningd, but will forward it directly.
That was the effect before, anyway.

Rusty Russell 00a0d09340 tools/check-includes.sh: test that c files include their .h files.
This is best-practice (to ensure prototypes match up), but there were a
few places we didn't (at least, directly).  Make it a requirement,
either of form "foo.h" or <dir/foo.h>.

The noise is the change to our print templates.

Rusty Russell cb22015b2a common/channel_type: wrapper for generated 'struct channel_type'.
We make it a first-class citizen internally, even though we won't use
it over the wire (at least, non-experimental builds).  This scheme
follows the latest draft, in which features are flagged compulsory.

We also add several helper functions.

Since uses the *even* bits (as per latest spec), not the *odd* bits,
we have some other fixups.

Rusty Russell 75720ad0e1 lightningd: wait for gossipd to finish initalizing before starting plugins.
This mainly helps our CI under valgrind, which starts a fresh instance
and immediately calls the invoice command.  This can cause the topology
plugin to try to access the gossmap file before it's created.

We can also move the gossmap reading in topology to init time.

Rusty Russell 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.

Rusty Russell 7b853d0fa5 gossip_store: don't make bogus assumption that writes are atomic wrt readers.
They're not defined to be, though we've not seen this on Linux (testing
showed that it is page-level atomic, which means it can still happen across
page boundaries though!).  This was pointed out by whitslack in
https://github.com/ElementsProject/lightning/issues/4288

In practice, this just means not complaining when it happens, and also
not trying to get tricky to use it on MacOS (we can safely seek & write,
since we're single-threaded).
