Rusty Russell 2bb365a931 common/route: route_from_dijkstra returns route_hop array.
This is what (most) callers actually want, so unify it into one place.

Rusty Russell 770a328d56 gossmap: save the offset where the channel updates are, function for details.
This takes an extra 8 bytes per channel, but means we can go back and
get more information about them; this is implemented in
gossmap_chan_get_update_details() which is what listchannels will need.

Christian Decker c78e2cc024 test: Fix memory leak in unit test run-gossmap_local
This was likely missed because we don't run the tests under valgrind anymore

I found this.

Rusty Russell c5bd518d2f gossmap: change local API.
Now we create a separate set of local mods, and apply and unapply it.
This is more efficient than the previous approach, since we can do
some work up-front.  It's also more graceful (and well-defined) when a
local modification overlaps an existing one.

Christian Decker 32000b6660 json: Add two param functions to parse string arrs and outpoint arrs
In a couple of places we accept arrays of strings and don't validate
them. If we forward them, e.g., call a JSON-RPC method from the
plugin, we end up embedding the unverified string in the JSON-RPC
call without escaping, which then leads to invalid JSON being passed
on.

This at least partially causes #4238

niftynei 4508584b21 dualfund: rearrange things so that the wire-dependent calls are separate
There's a few structs/wire calls that only exist under experimental features.
These were in a common file that was shared/used a bunch of places but
this causes problems. Here we move one of the problematic methods back
into `openingd`, as it's only used locally and then isolate the
references to the `witness_stack` in a new `common/psbt_internal` file.

This lets us remove the iff EXP_FEATURES inclusion switches in most of
the Makefiles.

Rusty Russell d5cb0d85b5 utils: use a cleaner pattern to capture wally allocations.
We force use of tal_wally_start/tal_wally_end around every wally
allocation, and with "end" make the caller choose where to reparent
everything.

This is particularly powerful where we allocate a tx or a psbt: we
want that tx or psbt to be the parent of the other allocations, so
this way we can reparent the tx or psbt, then reparent everything
else onto it.

Implementing psbt_finalize (which uses a behavior flag antipattern)
was tricky, so I ended up splitting that into 'psbt_finalize' and
'psbt_final_tx', which I think also makes the callers clearer.
