Subject: Allow `txn-mempool-conflict` errors when broadcasting transactions
X-Git-Url: http://git.bitcoin.ninja/index.cgi?p=ldk-sample;a=commitdiff_plain;h=c743491c5a2bbecebb46c16f35209d399bbbd67a

Allow `txn-mempool-conflict` errors when broadcasting transactions

This can be seen, among other times, when a channel is
cooperatively- (or counterparty-)closed and we restart, causing us
to attempt to broadcast our local commitment tx, which conflicts
with the original closing transaction.
