4ffda340d3 check: make sure all files outside contrib/ include "config.h" first.
And turn "" includes into full-path (which makes it easier to put
config.h first, and finds some cases check-includes.sh missed
previously).

config.h sets _GNU_SOURCE which really needs to be done before any
'#includes': we mainly got away with it with glibc, but other platforms
like Alpine may have stricter requirements.

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Changelog-Fixed: errors: Errors returning a `channel_update` no longer return an outdated one.

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.

We assume if they set this to 0 (which nobody did previously), they're

83aea6b2bb gossip_store: make private channels more similar to channel_announcement
Instead of a boutique message, use a "real" channel_announcement for
private channels (with fake sigs and pubkeys).  This makes it far
easier for gossmap to handle local channels.

Backwards compatible update, since we update old stores.

We also fix devtools/dump-gossipstore to know about the tombstone markers.

Since we increment our channel_announce count for local channels now,
the stats in the tests changed too.

b0c9059602 tools/generate-wire: no more lonely messages!
When we have only a single member in a TLV (e.g. an optional u64),
wrapping it in a struct is awkward.  This changes it to directly
access those fields.

This is not only more elegant (60 fewer lines), it would also be
more cache friendly.  That's right: cache hot singles!

Now that we have json_stream in common/, we can move all the related
helpers from lightningd/json to common/json. This way everyone can
benefit of them (including libplugin, the plugins themselves,

Note that the Makefile of the common/test/ had to be modified, because
the new helpers make use of common/wireaddr... Which turns out to
\#include <lightingd/lightningd.h> ! So we couldnt just include the .c
and add mocks if we redefined some structs (hello run-param).
