    pluto: more tidying around x509 code
    
    - sprinkle const
    
    - tweak control flow
    
    - reduce scope of auto variables
    
    - reduce range where a variable is uninitialized
    
    - make dntoasi safer and more convenient to use:
    
      + add dntoasi_buf_t
    
      + return a pointer to the resulting string
    
    - exploit struct initializers for autos
    
    - use DBGF
    
    - eliminate code to handle impossible situations: it just adds
      confusion
    
    - eliminate pointless initializers
