move some utility functions inside octave namespace
* lo-utils.h, lo-utils.cc (is_one_or_zero): Rename from
xis_one_or_zero and move inside octave namespace. Change all uses.
(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.
