invoice_path_id is actually a generic path_id thing, so rename it.
We're going to use the same scheme for path secrets and the tweak to
node_id when we create a fake pubkey for invoice_requests, so a new
header is appropriate.

This is complicated, and I needed to write it down. All the current routines
are spread through the code, and I wanted it all in one place.
This implementation also support *joining* two paths together, which we
previously didn't.

Currently make a plugin that do reportings of logs on
a services like graphana is not possible. So this commit
include the possibility to write a plugin that do the report
of this analisys.
Changelog-Added: core: notify plugins when a log line is emitted.

We use an array of bit numbers. We could use an array of names, but the JSON typing is then harder.

Each feature has a name, and says when deprecation begins and ends.
There's an API coming to allow you to re-enable on a per-feature basis
even if it's ended (as long as it's not been removed from the code ofc!).
Default end is 6 months after deprecation, i.e. we complain about it
at that point, if we can detect its use.
e.g, a standard deprecation in v24.05:
v24.02: allowed
v24.02 with mods: allowed
master after v24.02: allowed unless deprecated APIs disabled.
v24.05: allowed unless deprecated APIs disabled.
v24.08: allowed unless deprecated APIs disabled.
v24.11: allowed unless deprecated APIs disabled, but logs at BROKEN level.
v25.02: allowed only if --i-promise-to-fix-broken-api-user=FEATURE.
v25.05: code is actually removed.

This is more thorough than the minimal one required for getroute(), including the feerates
and cltv deltas.

These are gathered from the config files and the commandline, but the
process is rather complex! We want to remember where the options came
from in future (for a `setconfig` command), and also generalize
and simplify handling.

The "path" is just a message to ourselves. This meets the minimal
requirement for bolt12 invoices: that there be a blinded path (at
least so we can use the path_id inside in place of "payment_secret").
We expose the method to make this path_id to a common routine: offers
will need this for generating more sophisticated paths.

Takes the dualopen collaborative transaction building and makes it available for other daemons to use
Changelog-Added: Added interactive transaction building routine
Instead of open coding in connectd/onion_message, we move it to common
with a nice API.
This lets us process the BOLT test vectors.

Don't shoehorn it into onion_nonfinal_hop() and onion_final_hop(), but
provide an explicit routine "blinded_onion_hops" and an onion helper
"onion_blinded_hop()" for it to call.

With the rise of external HSMs like VLS, this is no longer an
internal-only API. Fortunately, it doesn't change very fast so
maintenance should not be a huge burden.

We have them split over common/param.c, common/json.c,
common/json_helpers.c, common/json_tok.c and common/json_stream.c.
Change that to:
* common/json_parse (all the json_to_xxx routines)
* common/json_parse_simple (simplest the json parsing routines, for cli too)
* common/json_stream (all the json_add_xxx routines)
* common/json_param (all the param and param_xxx routines)

connectd does this internally now using ccan/io, with appropriate
credit for ZmnSCPxj who wrote this code in the first place.

Now connectd is doing the crypto, we can use normal wire io. We
create helper functions to clearly differentiate between "peer" comms
and intra-daemon comms though.

We make it a first-class citizen internally, even though we won't use
it over the wire (at least, non-experimental builds). This scheme
follows the latest draft, in which features are flagged compulsory.
We also add several helper functions.
Since uses the *even* bits (as per latest spec), not the *odd* bits,
we have some other fixups.

The fetchinvoice and offers plugins disable themselves if the option

Our new "decode" command will also handle bolt11. We make a few cleanups:
1. Avoid type_to_string() in JSON, instead use format functions directly.
2. Don't need to escape description now that JSON core does that for us.

This avoids duplication of both logic and error-prone values, such as
the salt. Grouping all hsm encryption logic into a public API will also
allow us to fuzz it.
