The new spec removes the offer_id, in favor of mirroring all the
fields. So we need a way of generating a convenient identifier to
identify the offer, and this works.
We also want to extract parts of streams elsewhere, so expose that.

It's just to a direct peer, and we only create one, but this is
enough to test, and make payments to non-public nodes work.

This is needed for offers to generate blinded paths.
No documentation changes since listincoming is an undocumented
internal hack interface which topology presents for production
of routehints.

And check it in invoice.c, insead of a hack where we compare against invhash.
Restore checking, too.

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.

Instead of doing command_fail() in the else, do it immediately then
unindent the normal path.
No code changes.

We had a scheme where lightningd itself would put a per-node secret in
the blinded path, then we'd tell the caller when it was used. Then it
simply checks the alias to determine if the correct path was used.
But this doesn't work when we start to offer multiple blinded paths.
So go for a far simpler scheme, where the secret is generated (and
stored) by the caller, and hand it back to them.
We keep the split "with secret" or "without secret" API, since I'm
sure callers who don't care about the secret won't check that it
doesn't exist! And without that, someone can use a blinded path for a
different message and get a response which may reveal the node.

We actually want lightningd to create these, since it wants to put the
path_id secret in the last element. So best API is actually a generic
one, rather than separate APIs to create first and last ones.
And really, the more explicit initialization makes the users clearer.

We simply take the first one, and route to the start of that. Then we
append the blinded path to the onion construction.

This current spec is not strict enough: we might complain that the
next peer is not connected, for example, which leaks information.
So return WIRE_INVALID_ONION_BLINDING even if we're the first hop
on the path, to be safe.

This makes us match eed2ab0c30ad7f93e3b2641ca9d7ade32f3d121d
("Use `invalid_onion_blinding` everywhere").
1. Numerous typographical changes.
2. Make sure we *always* return WIRE_INVALID_ONION_BLINDING if
we're in a blinded path.
3. Handle p->total_msat correctly (MPP payments).
4. Reorganize blinding handling just like spec order.

Since the "struct command" is different from plugins and lightningd, we
need an accessor for this to work (the plugin one is a dummy for now!).

The runner version was recently bumped causing our tests to fail
because it couldn't find the `poetry` version it just installed. We
instead install python3.10, and force its use, since otherwise we end
up compiling grpcio and fail to do so.

1. Remove the very concept of ONION_REPLY_SIZE, instead make it a
local variable in create_onionreply().
2. Use the proper fromwire_ primitives in unwrap_onionreply() so we
don't have to do explicit length checks.
3. Make fromwire_tal_arrn() return NULL if it fails to pull, instead of
a zero-length allocation.

Changelog-Fixed: Protocol: we now correctly decrypt non-256-length onion errors (we always forwarded them fine, now we actually can parse them).
Reckless was failing to install multiple plugins due to git not
appreciating the cwd being a now removed dir after the first plugin
tmp files were cleaned up.
While loading the appropriate lightningconfig file, it is now checked
against the active config file in lightningd. Because a deviation from the
default file structure would not be possible, a -conf option is also added
to explicitly pass the lightningd config file into reckless.
This also simplifies dynamic enable/disable by catching the exception
raised when the cli is unable to connect to RPC (lightningd offline or
misconfigured relative to reckless).
This change makes it easier to follow retrieval of parent directories.
Additional os.path operations replaced with their pathlib.Path equivalents
to keep module usage consistent.
The goal was to support passing a list to install, enable, etc. in order
to improve performance. Passing lists to most of the functions was less
practical than iterating through the items from the top level.
`reckless help <cmd>` previously called the function docstring. This could
be updated to use the subparser help, but would require a strict naming
convention or a dictionary. Providing a hint to use the built-in
contextual help via the option flag is hopefully sufficient.
Regtest environments commonly use explicit definition of the config
file for lightningd. This can be queried and utilized by default,
saving redundant definitions between lightning and reckless.
