Subject: Expose `ChannelMonitor::get_counterparty_node_id`
X-Git-Url: http://git.bitcoin.ninja/index.cgi?a=commitdiff_plain;h=e87762b652fc41d0986eb0693a2ef4b7ba8209ff;p=rust-lightning

Expose `ChannelMonitor::get_counterparty_node_id`

This fixes an oversight in ac842ed9dd7a36a4a26eb6b856d80ab04eecf750
namely that it left users unable to implement their own
`ChainMonitor` from outside of the `rust-lightning` crate.
