Migrate all btcd dependencies to the new per-package v2 modules (wire/v2, txscript/v2, chaincfg/v2, chainhash/v2, btcutil/v2, psbt/v2, btcec/v2) introduced by btcd v0.26.0, and pin the tagged ecosystem versions: btcwallet v0.17.0, neutrino v0.18.0 and lightning-onion v1.4.0. The bulk of the import rewrite was produced by the scripted diff from https://github.com/btcsuite/btcd/pull/2547 (followed by 'make rpc'). The address symbols that moved out of btcutil into the new address package are imported as btcaddr where a local "address" variable would otherwise shadow them. The go.mod/go.sum updates and the remaining manual compilation fixes are folded into this single commit so it builds on its own (the migration was previously split into a reproducible scripted-diff plus follow-ups, intended to be squashed on merge). |

chainntnfs
The chainntnfs package implements a set of interfaces which allow callers to receive notifications in response to specific on-chain events. The set of notifications available include:
- Notifications for each new block connected to the current best chain.
- Notifications once a
txidhas reached a specified number of confirmations. - Notifications once a target outpoint (
txid:index) has been spent.
These notifications are used within lnd in order to properly handle the
workflows for: channel funding, cooperative channel closures, forced channel
closures, channel contract breaches, sweeping time-locked outputs, and finally
pruning the channel graph.
This package is intentionally general enough to be applicable outside the
specific use cases within lnd outlined above. The current sole concrete
implementation of the ChainNotifier interface depends on btcd.
