    pluto: build payloads with struct initializers; tidy
    
    These changes are linked by changes to np (next payload) emitting.
    
    - for output payload structs, switch to using struct initializer to
      fill in fields where possible.  This replaced field assignment subsequent
      to the struct declaration
    
    - fix leaks of auth_chain and add comments to explain required discipline
    
    - sprinkle more "const"
    
    - reduce scope of auto variables by declaring them as late as possible.
    
    - try to combine declaration of each auto variable with its initial
      assignment
    
    - eliminate out_modify_previous_np
