Quiescence #869
@rustyrussell can you (or someone else with access to the branch) rebase the PR? We've started cross-compat tests between eclair and lnd, it's looking good, so we should be able to merge it soon
there are also a couple of comments asking for some small additions to clarify a few subtleties, but nothing major

Here is the PR that clarifies the aforementioned subtleties: rustyrussell#15
