It's a u64, we should pass by copy. This is a big sweeping change,
but mainly mechanical (change one, compile, fix breakage, repeat).

This has the benefit of being shorter, as well as more reliable (you
will get a link error if we can't print it, not a runtime one!).

We have various functions to convert to a string, rename them all so we can
count on fmt_X being the formatter for struct X, and make them all return
`char *`.
Sometimes they existed but were private, sometimes they had a
different name. Most take a pointer, but simple types pass by copy:
short_channel_id, amount_msat and amount_sat.
The following public functions changed:
1. psbt_to_b64 -> fmt_wally_psbt.
2. pubkey_to_hexstr -> fmt_pubkey.
3. short_channel_id_to_str -> fmt_short_channel_id (scid by copy now!)
4. fmt_signature -> fmt_secp256k1_ecdsa_signature
5. fmt_amount_sat/fmt_amount_msat pass copy not pointer, return non-const char *.
6. node_id_to_hexstr -> fmt_node_id

If we accept a channel_update in state "NEED_SIGS" we should not set
refresh timer: we're simply holding it for the moment we get to that state
(which will happen as we mine the block).

This was triggered by the recover plugin tests (not yet merged!) and causes a crash
because we don't have signatures yet. It can only happen if we lost our database,
but at least don't crash!

It's an unnecessary round-trip, and can cause us to complain in CI, in
the case where the channel has been closed by the time we ask.

This caused a flake in test_gossip_lease_rates, since the peer would ignore
the node_announcement due to duplicate timestamps!

This is a nice reflection of channel stability: in particular, worse case
ping time is 45 seconds, so we should have had some traffic.

This is useful to see if we've really made progress, or just bounced
off the peer (e.g. it doesn't know the channel, or we have fallen
behind somehow).
Changelog-Added: JSON-RPC: `listpeerchannels` new field `reestablished` set once we've exchanged `channel_reestablish` messages.

In particular, we were sending `announcement_signatures` before
`channel_reestablish`; we allow this because LND used to do it, but
it's not spec compliant.

It then waits 10 more seconds (for plugins to call setlease, especially)
before it will update a node_announcement.
