Please linewrap your commit description.
You should also leave out __pure in .c files, it won't do anything
useful there, since it's relevant to callers only.
Also, you can leave out out of comparator functions for avl and kvlist.
Since they're stored as a function pointer in the tree struct and called
from there, there's no way that this can ever help the compiler make a
better decision.
