This was introduced to allow creating a shared secret, but it's better to use
makesecret which creates unique secrets. getsharedsecret being a generic ECDH
function allows the caller to initiate conversations as if it was us; this
is generally OK, since we don't allow untrusted API access, but the commando
plugin had to blacklist this for read-only runes explicitly.
Since @ZmnSCPxj never ended up using this after introducing it, simply

The old model of coin movements attempted to compute fees etc and log
amounts, not utxos. This is not as robust, as multi-party opens and dual
funded channels make it hard to account for fees etc correctly.
Instead, we move towards a 'utxo' view of the onchain events. Every
event is either the creation or 'destruction' of a utxo. For cases where
the value of the utxo is not (fully) debited/credited to our account, we
also record the output_value. E.g. channel closings spend a utxo who's
entire value we may not own.
Since we're now tracking UTXOs onchain, we can now do more complex
assertions about the onchain footprint of them. The integration tests
have been updated to now use more 'chain aware' assertions about the
ending state.

We were always prefixing the `message` field with the internal type

the type being constant is of no interest to the plugin and the length
being implicit due to the JSON-encoding.

Secondly, we assume that the wallet considers outputs spent as soon as

This adapts our fee estimations requests to the Bitcoin backend to the

We now keep track of more fine-grained feerates:
- `opening` used for funding and also misc transactions
- `mutual_close` used for the mutual close transaction
- `unilateral_close` used for unilateral close (commitment transactions)
- `delayed_to_us` used for resolving our output from our unilateral close
- `htlc_resolution` used for resolving onchain HTLCs

This completes the custommsg epic, finally we are back where we began all that
time ago (about 4 hours really...): in a plugin that implements some custom
logic.
This solves a couple of issues with the need to synchronously drop the
connection in case we were required to understand what the peer was talking
about while still allowing users to experiment, just not kill connections.
This is needed to fully implement handling of blockheight disagreements
between us and payee.
If payee believes the blockheight is higher than ours, then `pay`
should wait for our node to achieve that blockheight.
Changelog-Add: Implement `waitblockheight` to wait for a specific blockheight.
Some Linux OSs impose a length limit on the path a Unix socket may have. This
is not an issue in `lightningd` since we `chdir()` into that directory before
opening the socket, however in pyln this became a problem for some tests,
since we use absolute paths in the testing framework. It's also a rather
strange quirk to expose to users.
This patch introduces a `UnixSocket` abstraction that attempts to work around
these limitations by aliasing the directory containing the socket into
`/proc/self/fd` and then connecting using that alias.
