mod_smacks: Refactor ack requesting to avoid some timer roundtrips The function was too large to comprehend! Breaking it up helps readability and reuse. The timer round rip is only to avoid ordering weirdness when sending from inside a stanza filter. No need when handling <r> and <a> CSI interactions both boiled down to sending an <r> immediately.
