Add static compile-time checking of printf functions in liboctave. * util/lo-error.h: Use macro OCTAVE_FORMAT_PRINTF for printf functions. * array/Array.h: Use format specifier "z" for type size_t. * array/Array-util.cc, numeric/oct-norm.cc: Supply a format string of "%s" when printing a single string. * array/idx-vector.cc, array/MatrixType.cc, array/Sparse.cc, numeric/DASPK.cc, numeric/DASRT.cc, numeric/DASSL.cc, numeric/LSODE.cc, util/lo-array-errwarn.cc, util/sparse-util.cc: Use preprocessor macro OCTAVE_IDX_TYPE_FORMAT as the format identifier for octave_idx_type. * util/f77-fcn.c: Cast width argument to int. * util/lo-utils.cc: Pass missing argument c0.
