Subject: Implement AsyncPaymentsMessageHandler for ChanMan and use everywhere
X-Git-Url: http://git.bitcoin.ninja/index.cgi?a=commitdiff_plain;h=969578703db85ba62410e121e61fb512be000f0d;p=rust-lightning

Implement AsyncPaymentsMessageHandler for ChanMan and use everywhere

Dummy implementation for now. This avoids having to change a bunch of type
signatures in the future when we replace the dummy impl with a real one.
