    PR13261: Added map->wrap mode to script parser
    
    To activate map->wrap mode, use the '%' symbol after the variable name
    in a global declaration, for example:
    
      global foo%[100]
    
    This will let it automatically replace elements in the map if you
    try to place something out of bounds, rather than give an error.
    It also works for statistics-valued arrays.
    
    parse.cxx
      Checked for the '%' symbol in parser::parse_global(), and if
      present, sets the vardecl* d->wrap value to true.
    
    staptree.cxx
      Set the default value of the new vardecl->wrap boolean value to false.
      Added the '%' to the hash if it is enabled.
    
    staptree.h
      Added the bool wrap element to struct vardecl
    
    translate.cxx
      Added the bool wrap element to struct mapvar and initialixed it to the
      wrap element of the associated vardecl variable.
      Checked whether the mapvar->wrap has been set (from vardecl->wrap set
      in parser::parse_global()).
      If so, added the apropriate code to set the map->wrap for whether its a
      map or a pmap.
