147eaced2e developer: consolidiate gossip timing options into one --dev-fast-gossip.
It's generally clearer to have simple hardcoded numbers with an
#if DEVELOPER around it, than apparent variables which aren't, really.

Interestingly, our pruning test was always kinda broken: we have to pass
two cycles, since l2 will refresh the channel once to avoid pruning.

Do the more obvious thing, and cut the network in half and check that
l1 and l3 time out.

ee3480e56b derive_keyset: don't rotate key for remote iff option_static_remotekey.

It can also now resolve unknown commitments, even if it doesn't have a

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.
