aa23c2a2b2 script: consistently take the script length in identification functions
Standardizes the is_xxx script function all take a script length, and changes
their first-level callers to pass it. This has several knock on benefits:

- We remove the repeated tal_count/tal_bytelen calls on the script, in
  particular the redundant calls that result when we must check for multiple
  types of script - which is almost all cases.
- We remove the dependency on the memory being tal-allocated (It is, in
  all cases, but theres no reason we need to require that).
- We remove all cases where we create a copy of the script just to id it.
- We remove all allocations for non-interesting scripts while iterating block
  txs in process_getfilteredblock_step1().
- We remove all allocations *including for potentially interesting scripts* in
  topo_add_utxos().

1f45dd1acb wally: rename functions that clash with wally v1.0.0
Rename the offending functions from wally_foo to cln_wally_foo.

For the sake of a minimal diff, only calls which conflict with wally
v1.0.0 have been changed. However it is bad form to use the wally_
function namespace; the remaining such calls should also be renamed.

Changelog-None

843fae7caf psbt: fix PSBT mutation in the changeset
During the changeset calculation after the `openchannel2_sign`
hook.

So this commit patch the problem with the following change:

- Addressed an issue where `psbt_get_changeset` was modifying the original PSBT unnecessarily.
- This modification led to problems with a different hsmd, as referenced in [Issue #6672](https://github.com/ElementsProject/lightning/issues/6672).
- Noted a potential optimization where only a subpart of the PSBT
needs to be cloned, as the mutation is specific to inputs.

00a0d09340 tools/check-includes.sh: test that c files include their .h files.
This is best-practice (to ensure prototypes match up), but there were a
few places we didn't (at least, directly).  Make it a requirement,
either of form "foo.h" or <dir/foo.h>.

0f05238e97 psbt: set the witness script to null, also

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.

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.

6371a49ee3 psbt: sort maps before serializing, to stabilize comparison
Our psbt input/output comparison functions use serialization to compare
the things, but if there's a map with things in it and the map isn't
sorted exactly the same, it's highly likely you'll mark an identical inputs
as different.

To fix this, we sort all the input/output maps before linearizing them.

722fa1df6c psbt-utils: ignore the 'unknown' map for input + output comparison
There's no stable ordering on unknown serialization, so linearizing
identical but mis-ordered unknown data will lead to 'wrong' results.
Instead, we just ignore any data that's in the psbt unknown struct.

There's probably also problems here with other PSBT maps. Really, this
needs a finer grained comparison function .... fuck
