Pierre-Marie Padiou ee7038c7a6 Rework mutual closing (#247) ... * include raw tx when sig check fails See BOLT 1 recommendation: "when failure was caused by an invalid signature check: SHOULD include the raw, hex-encoded transaction in reply to a funding_created, funding_signed, closing_signed, or commitment_signed message." Also, removed redundant signature check in state `WAIT_FOR_FUNDING_SIGNED`. * enforce closing fee <= commitment fee In accordance to BOLT 2. Note that it is safe to consider feerates instead of fees, because weight(closingTx) < weight(commitTx). This fixes #243. * use channel logger in Helpers.scala and Commitment.scala * handle multiple closing txes Nothing prevents the counterparty to publish any or several of the closing txes before the negotiation is finished, we need to handle this case. This fixes #245. * added msg+state when chanel failure occurs * proper handling of invalid closing sig * removed hardcoded error messages in channel * return an `error` to sync attemps when in CLOSING * peer now return an error for unknown channels * added fee negotiation details in logs * properly display errors, reject closing fee to high		2017-12-06 13:53:09 +01:00
