226e2aee48 option_static_remotekey: update to latest draft.
531c8d7d9b

In this one, we always send my_current_per_commitment_point, though it's
ignored.  And we have our official feature numbers.

ee3480e56b derive_keyset: don't rotate key for remote iff option_static_remotekey.
The largest change is inside hsmd: it hands a null per-commitment key
to the wallet to tell it to spend the to_remote output.

It can also now resolve unknown commitments, even if it doesn't have a
possible_remote_per_commitment_point from the peer.

We don't rotate key for option_static_remotekey, so we don't need

7514a87b5e common/gossip_rcvd_filter: avoid DoS.
If they don't send us a gossip timestamp filter, we won't be sending
them any gossip, thus won't be aging the gossip_rcvd_filter.  So
restrict it to 10,000 elements just to be sure.

2652cc9704 common/memleak: simplify notleak() handling.
Use the same "child of tal object" trick to mark things "notleak".

That simplifies things and means we don't have to track them being
reallocated.

aca2e4f722 common/memleak: add dynamic hooks for assisting memleak.
Rather than reaching into data structures, let them register their own
callbacks.  This avoids us having to expose "memleak_remove_xxx"
functions, and call them manually.

Under the hood, this is done by having a specially-named tal child of
the thing we want to assist, containing the callback.

837e6232c3 common: reduce header differences for DEVELOPER vs non-DEVELOPER.
`make update-mocks` is usually run in DEVELOPER mode, but then it includes
definitions for functions which aren't declared in non-DEVELOPER mode.

We hacked this in a few places, but it's fragile, and worst, now we
have EXPERIMENTAL_FEATURES as well, it's complex.

Instead, declare developer-only functions (but don't define them).
This is a bit more awkward if you accidentally use one in
non-DEVELOPER code (link error rather than compile error), but makes
autogenerating test mocks much easier.

ca28c30eff funding: don't allow funding new channels until we're synced.
This is probably worth preventing.

1. Our depth estimate would be inaccurate possibly leading to us
   timing out too early.
2. If we're not up-to-date our onchain funds are unknown.
3. We wouldn't be able to send or receive HTLCs until we're synced anyway.
