    libswan: tidy secrets.[ch]
    
    - eliminate deadwood from secrets.h.  Some functions disappear, some
      become file-static.
    
    - sprinkle const
    
    - simplify control flow of functions
    
    - reduce scope of autos
    
    - move asssignments embedded in boolean expressions
    
    - delete unused and buggy lsw_get_defaultsecret()
    
    - add add_secret(), absorbing create_empty_idlist() and eliminating
      duplicated and error-prone code
    
    - in lsw_find_secret_by_id(), print match values in octal (more natural)
    
    - add a few ??? comments
