Remove liboctave methods and classes deprecated for longer than 3 years. * Array2.h, Array3.h, ArrayN.h, MArray2.h, MArrayN.h: remove these files with their corresponding classes which have been deprecated. * numeric/lo-mappers.h, numeric/lo-mappers.cc (octave_is_NaN_or_NA): remove deprecated function for input of doubles and floats. * util/lo-ieee.h, util/lo-ieee.cc (__lo_ieee_float_is_NaN_or_NA): remove deprecated function for input of doubles and floats. * array/Array.h (Array<T>::chop_trailing_singletons): remove deprecated method. * array/Array.h (Array<T>::Array (octave_idx_type), Array<T>::Array (octave_idx_type, T)): remove deprecated constructors which casused confusions since there are no 1D arrays. * dim-vector.h (dim_vector::dim_vector (octave_idx_type)): remove deprecated constructor which caused confusion since there are no 1D arrays. * liboctave/array/module.mk: update list of files.
