Update Bitcoin Core to v28.x. This releases contains the following interesting features: - automatic utxo unlocking on wallet conflicts - support for testnet4 - 1-parent 1-child package relay (channel force-close) - `max_tx_weight` parameter to `fundrawtransaction`
In order to use opportunistic package relay (with 1-parent-1-child) we must use confirmed inputs when funding our anchor transactions. This will also be a requirement when using v3 transactions. We also take this opportunity to honor the `require_confirmed_inputs` parameter set by our peer during `interactive-tx`.
We use bitcoin core's `submitpackage` RPC to publish our local commit tx and its anchor transaction. This ensures that even if we have the remote commit in our mempool, it will be replaced by our local commit. We will also be able to get our local commit propagated even if its feerate is below the mempool minimum feerate, as long as enough nodes run bitcoin core v28 or higher.

Start using package relay for anchor channels, thanks for opportunistic relay added to bitcoind v28.x.
