Fix some const confusion with simpler code.

  Fix some const confusion with simpler code.

  XXX note that 1.3.13 grew the xmethods in some recent patch:
  typedef struct {
    table *action_types;       /* Added with Action... */
    char *scripted[METHODS];   /* Added with Script... */
    array_header *xmethods;    /* Added with Script -- extension methods */
  } action_dir_config;
  XXx seems like whoever applied needs to port forward to 2.0 :-)
