See lightning/bolts#728 Add an additional reserve on the funder to prevent emptying and then being stuck with an unusable channel. As fundee we don't verify funders comply with that change. We may enforce it in the future when we're confident the network as a whole enforces that.

We may enforce it in the future when we're confident the network as a whole enforces that.
Note that c-lightning has already implemented the same logic. We can merge this regardless of spec inclusion as a safety measure for our nodes (and I think we should). The spec may bikeshed some details (like the factor) which we can update later.
@pm47 this is now ready for review.
