We now track all pending RPC passthrough calls, and terminate them with an
error if the plugin dies.
Changelog-Fixed: JSON-RPC: Pending RPC method calls are now terminated if the handling plugin exits prematurely.
The spec states that invoices with an amount, but lacking a multiplier, should
be interpreted as integer Bitcoin amounts:
`amount`: optional number in that currency, followed by an optional
`multiplier` letter. The unit encoded here is the 'social' convention of a
payment unit -- in the case of Bitcoin the unit is 'bitcoin' NOT satoshis.

Changelog-Fixed: invoice: The invoice parser assumed that an amount without a multiplier was denominated in msatoshi instead of bitcoins.
We had them split according the separate use-cases:
- testing
- doc-gen
- wire-gen
But that was causing new contributors to miss some dependencies when they
first got hacking. So this consolidates all of our own dependencies in a root
requirements.txt, with the notable exception of `pyln-client`, `pyln-testing`
and `pyln-proto` which are distributed as PyPI modules and therefore have
their own dependencies that need to be tracked in the module root.
Closes#3518
Note that now we check capacity once we've figured out which peer, which
broke a test (we returned "unknown peer" instead of "capacity exceeded"),
so we rework that too.

Shows what features we use in various contexts, including those added
by plugins in getmanifest.

Changelog-Added: Plugin: `feature_set` object added to `init`
A CONSERVATIVE/3 target for them.
Some noisy changes to the tests as we had to update the estimatesmartfee
mock.
Changelog-Changed: We now use a higher feerate for resolving onchain HTLCs and for penalty transactions
Changelog-Fixed: Passing 0 as minconf to withdraw allows you to use unconfirmed transaction outputs, even if explicitly passed as the `utxos` parameter
This is to prepare for dynamic features, including making plugins first
class citizens at setting them.

This restriction was removed from the spec as of
86c2ebcc5973a4133d3ce4d80ae1c203061a1646.
We also fix up some strange formatting in that part of the documentation.
Changelog-changed: We now announce multiple addresses of the same type, if given.

Changelog-Removed: JSON: `fundchannel` and `fundchannel_start` `satoshi` parameter removed (renamed to `amount` in 0.7.3).
This adapts our fee estimations requests to the Bitcoin backend to the
new semantic, and batch the requests.
This makes our request for fees much simpler, and leaves some more
flexibility for a plugin to do something smart (it could still lie before
but now it's explicit, at least.) as we don't explicitly request
estimation for a specific mode and a target.
Changelog-Changed: We now batch the requests for fee estimation to our Bitcoin backend.
Changelog-Changed: We now get more fine-grained fee estimation from our Bitcoin backend.
We kept track of an URGENT, a NORMAL, and a SLOW feerate. They were used
for opening (NORMAL), mutual (NORMAL), UNILATERAL (URGENT) transactions
as well as minimum and maximum estimations, and onchain resolution.
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
- `penalty` used for resolving revoked transactions
We don't modify our requests to our Bitcoin backend, as the next commit
will batch them !
Changelog-deprecated: The "urgent", "slow", and "normal" field of the `feerates` command are now deprecated.
Changelog-added: The fields "opening", "mutual_close", "unilateral_close", "delayed_to_us", "htlc_resolution" and "penalty" have been added to the `feerates` command.
pytest captures the output by monkey patching out `sys.stdout`. This may
conflict with our use of `sys.stdout` when configuring logging, resulting in
the "Write to closed file" issue that is spamming the logs. By making the
logging configuration a fixture hopefully we always use the correct
stdout (after pytest has monkey-patched it).
Some tests may not spawn a node at all, so make sure that our assumption that
the directory exists in the fixture cleanup is correct by creating the
directory.
a few things. one is that `is_in_log` returns a result rather than
enforcing a condition. so these lines all need asserts
two is that with the 'allow_deprecated_apis' option on, the python json
parser overwrites the now typed input with the later-added string
version, so the only option value present in the option key-value set is
the last, string one. the check for this has been updated to only verify
that the string version is included (i manually verified that both are
printed to the JSON message)
We were nesting like the following:
```json
{"params": {
"rpc_command": {
"rpc_command": {
}
}
}
```
This is really excessive, so we unwrap once, and now have the following:
```json
{"params": {
"rpc_command": {
}
}
```
Still more wrapping than necessary (the method is repeated in the `params`
object), but it's getting closer.
Changelog-Deprecated: JSON-RPC: Removed double wrapping of `rpc_command` payload in `rpc_command` JSON field.

Before this patch we would only update `channel->last_tx` with the newly
proposed closure tx from the peer if the fee of the new one was lower.
In negotiations where we are at the higher end and the peer starts
lower, all peer's subsequent proposals will be higher than his initial
proposal and in this case we would never update `channel->last_tx`
and would wrongly broadcast his initial proposal at the end of the
negotiation.
Fixes https://github.com/ElementsProject/lightning/issues/3549
Changelog-Fixed: Always broadcast the latest close transaction at the end of the close fee negotiation, instead of sometimes broadcasting the peer's initial closing proposal.
We are returning a `BADONION` error despite the cause being an invalid onion
payload containing an unknown even TLV type. It really should return
`INVALID_ONION_PAYLOAD` errors instead.
ChangeLog-Added: New `getsharedsecret` command, which lets you compute a shared secret with this node knowing only a public point. This implements the BOLT standard of hashing the ECDH point, and is incompatible with ECIES.
Instead of saving a stripped_update, we use the new
local_fail_in_htlc_needs_update.
One minor change: we return the more correct
towire_temporary_channel_failure when the node is still syncing.
