Add SubmitPackage to the lnwallet.WalletController interface and a new WalletKit.SubmitPackage RPC, so a client of lnd can relay a package of related transactions (parents first, child last) through lnd's own chain connection. This lets a zero-fee v3/TRUC parent be accepted via its fee-paying CPFP child without the caller needing a separate connection to the chain backend. BtcWallet.SubmitPackage forwards to the chain backend's submitpackage for bitcoind/btcd, and broadcasts each transaction individually for neutrino (no mempool; relies on the peer's 1p1c package relay). The WalletKit handler maps the proto request/response to the btcjson result and is gated by the onchain:write macaroon permission. Mock controllers and the no-chain backend gain trivial implementations. |
