klist: implement klist_add_{after|before}()
Add klist_add_after() and klist_add_before() which puts a new node
after and before an existing node, respectively. This is useful for
callers which need to keep klist ordered. Note that synchronizing
between simultaneous additions for ordering is the caller's
responsibility.
