rHGf574cc00831a: node: make bin() be a wrapper instead of just an alias
rHGaba1d578c97f: node: make bin() be a wrapper instead of just an alias

Summary

This includes a full backout of 59affe7e and 30d0cb27. Per the review
of the former, we'd rather adapt the API to behave like it used to (at
least for now), and take a second run at it if it shows up in our
performance numbers. I ran perfrevlogindex with and without this
change and it didn't make a measurable difference, so maybe it's fine
(despite my intuition to the contrary).
