8370a627bb invoice: Parse amounts without a multiplier as BTC not msats
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.

Suggested-by: Stefano Pellegrini <@St333p>
Signed-off-by: Christian Decker <@cdecker>
Changelog-Fixed: invoice: The invoice parser assumed that an amount without a multiplier was denominated in msatoshi instead of bitcoins.

b68066e8e8 python: Consolidate requirements.txt files in a single place
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

158d2212c2 closingd: configurable closing fee negotiation step
When negotiating the transaction fee for closing a channel [1], we used
to always pick the middle of the range between our proposal and the
peer's proposal.

Introduce a new option `fee_negotiation_step` to the close command, so
the peer who initiates the close can choose his back off step.

Partially resolves https://github.com/ElementsProject/lightning/issues/3270

[1] https://github.com/lightningnetwork/lightning-rfc/blob/master/02-peer-protocol.md#closing-negotiation-closing_signed

Changelog-Added: New optional parameter to the `close` command to control the closing transaction fee negotiation back off step

d4fe4073a4 lightning/bitcoind: adapt and batch fees estimations
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.

dce2e87928 chaintopology: better feerate targets differentiation
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.

7201cb7315 pytest: Configure logging in a fixture to match stdout capturing
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).

a08905c344 plugin tests: actually check log result + move over to '' -> true
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)

d2688bbaf5 plugin: Unwrap the rpc_command payload
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.

66eca2ff3f lightningd: always broadcast the latest close tx
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.
