(is_zero): Rename from xis_zero and move inside octave namespace. Change all uses. (is_int_or_inf_or_nan): Rename from xis_int_or_inf_or_nan and move inside octave namespace. Change all uses. (too_large_for_float): Rename from xtoo_large_for_float and move inside octave namespace. Change all uses. (too_large_for_float): Rename from xtoo_large_for_float and move inside octave namespace. Change all uses. (is_int_or_inf_or_nan): Rename from xis_int_or_inf_or_nan and move inside octave namespace. Change all uses. (fgets): Rename from octave_fgets and move inside octave namespace. Change all uses. (fgetl): Rename from octave_fgetl and move inside octave namespace. Change all uses. (any_all_test, strsave): Move inside octave namespace. Tag uses with octave:: prefix as needed. * lo-utils.h: Provide deprecated templates and inline functions to preserve old names in global namespace.
