When using `sendonion` with `shared_secrets` we may be able to decode the
onioned error message but we cannot infer which node reported the failure
since we don't know which nodes where involved.
We are breaking with a couple of assumptions, namely that we have the
`path_secrets` to decode the error onion. If this happens we just want it to
error out.
This is what provides us with the ability to add custom fields in the payload
when using `createonion` so make sure we actually have access to it.
Changelog-Changed: The TLV payloads for the onion packets are no longer considered an experimental feature and generally available.
Changelog-Added: Plugins may now handle modern TLV-style payloads via the `htlc_accepted` hook

These are useful for the `createonion` JSON-RPC we're going to build next. The
secret is used for the optional `session_key` while the hex-encoded binary is
used for the `assocdata` field to which the onion commits. The latter does not
have a constant size, hence the raw binary conversion.
addresses issue #2753.
Formatting the JSON with the default parameters will escape the unicode
symbols in a way that c-lightning won't allow, leading to an exception.
Changelog-Fixed: `pylightning` now handles unicode characters in JSON-RPC requests and responses correctly.
This, in the case of data loss on a channel with `option_static_remotekey`
negotiated, allows to likely (if the dbid is not unreasonable) recover
the funds from a remote unilateral close just with the hsm_secret.
Changelog-added: A new command, 'guesstoremote', is added to the hsmtool. It is meant to be used to recover funds after an unilateral close of a channel with `option_static_remotekey` enabled.
We were using sleeps to hope we catch the password prompt. This makes the test
flaky. So I added a help text followed by a `fflush` to make sure we catcht he
right moment, instead of guessing. The `fflush` is also useful for debugging
if a user ever pipes the output to a file it'd get buffered and the user would
wait forever. The same applies for automated systems such as `expect` or
`pexpect` based scripts that enter the password on prompt.
In the c-lightning tests we have `tests/conftest.py` which annotates test
function with the outcome. If we use pyln-testing outside of the c-lightning
tree we cannot rely on that annotation being there, so we assume it passed.
Using the psycopg2-binary package means that the apropriate compiled binary
for the user platform will be shipped alongside the python binaries. Otherwise
the python bindings and the C shims would be shipped which would then require
the postgres development packages as well.
This just makes things easier, since we don't require the build dependencies.

fromwire_opening_got_offer_reply() allocates two fields off NULL:
err_reason and our_upfront_shutdown_script. err_reason is used
immediately afterwards (and was the leak detected here), so fixing
that is easy.
To fix the leak of our_upfront_shutdown_script, it makes sense to simply
make it a member of 'state'.

This will change the command `listconfigs` output in several ways:
- Deprecated the duplicated "plugin" JSON output by replacing it with
- a "plugins" array with substructures for each plugin with:
- path, name and their options
Changelog-Changed: JSON-RPC: `listconfigs` now structures plugins and include their options
Changelog-Deprecated: JSON-RPC: `listconfigs` duplicated "plugin" paths
The spec is (RSN!) going to explicitly denote where each feature should
be presented, so create that infrastructure.
Incorporate the new proposed bolt11 features, which need this.

We don't set the secret to compulsory (yet!) but put code in for the
future. Meanwhile, if there is a secret, check it is correct.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
In a future version, we will use features to insist that payers
provide the secret. In transition, we may have old invoices which
didn't insist on that, so we need to know this on a per-invoice basis.
Not sure if I got the right syntax for adding an empty blob though!

This was decided at a recent spec meeting: in particular, mpp and
var_onion_optin options will be used here.
We enhanced "features_supported" into "features_unsupported" so it
can return the first un-handlable bit number.

Also pulls in a new onion error (mpp_timeout). We change our
route_step_decode_end() to always return the total_msat and optional
secret.
We check total_amount (to prohibit mpp), but we do nothing with
secret for now other than hand it to the htlc_accepted hook.

Do the same thing '--help' does with them; append `...`.
Valgrind noticed that we weren't NUL-terminarting if answer was over
78 characters.
Changelog-Fixed: JSONRPC: listconfigs appends '...' to truncated config options.
