    libfdt: Add new errors for the overlay code
    
    Add a few new error codes to report the failure conditions we might
    encounter in the overlay application code:
       - FDT_ERR_BADOVERLAY, when an overlay cannot be parsed, even though its
         structure is correct
       - FDT_ERR_NOPHANDLES, when we ran out of available phandles and we
         cannot use a new phandle without either using an invalid one (-1 or
         0), or one already used.
