This commit removes the call toe `ListLeasedOutputs` in `LeaseOutput` -
the returned info from `ListLeasedOutputs` can easily be accessed via
`FetchInputInfo` and this info is only used at one callsite.
`ListLeasedOutputs` then becomes unnecessary here, plus it's very slow
and needs to be refactored in `btcwallet` instead.
This commit replaces the usage of `FetchInputInfo` with
`FetchOutpointInfo` and `FetchDerivationInfo` to remove unncessary
fetching of the derivation path.
To reflect the new sweeping behavior, also makes it easier to be used as
we need to method to quickly cleanup force closes without concerning the
details when we are not testing the force close behavior.
Previously we may get a floor feerate when calling `EstimateFeePerKW`
due to the fee estimator not finishing its startup process, which gives
us an empty fee map.
This is now fixed to return an error if the estimator is not started.
This commit adds a new expected field, `min_relay_feerate`, in the
response body returned from the API source, allowing the API to specify
a min relay feerate to be used instead of the FeePerKwFloor.
This change is backwards compatible as for an old API source which
doesn't specify the `min_relay_feerate`, it will be interpreted as zero.
This test was previously working because we'd mine an extra block to
confirm the coins inside `FundCoinsUnconfirmed` when it's a neutrino
backend, as shown in
https://github.com/lightningnetwork/lnd/blob/fdd28c8d888792ea8fde3c557ba9f2594e0a6ec8/lntest/harness.go#L1431
Since neutrino has trouble seeing unconfirmed balance, we now send some
coins to the wallet, confirm those, then do a self-transfer so the node
will have unconfirmed outputs to perform the test.
This commit makes sure the sweep requests are received before mining
blocks to trigger the actual sweeping.
In addition, `testFundingExpiryBlocksOnPending` is updated to deal with
the old `channel link not found` issue.
We may get a flake like the following,
```
lnd_route_blinding_test.go:468:
Error Trace: /Users/runner/work/lnd/lnd/itest/lnd_route_blinding_test.go:468
/Users/runner/hostedtoolcache/go/1.22.3/arm64/src/runtime/asm_arm64.s:1222
Error: Received unexpected error:
rpc error: code = Canceled desc = context canceled
Test: TestLightningNetworkDaemon/tranche15/144-of-156/bitcoind/disable_introduction_node
```
This happens when the test successfully finishes, the parent context is
canceled, causing the child context to return an error. We fix it by
ignoring it in the goroutine.
