octave: libinterp/corefcn/error.cc annotate

annotate libinterp/corefcn/error.cc @ 26596:cc0d942d0e20

Remove inconsistent warning "Octave:divide-by-zero" (bug #46650). * libinterp/corefcn/errwarn.h (warn_divide_by_zero), libinterp/corefcn/errwarn.cc (warn_divide_by_zero): Deprecate function "warn_divide_by_zero", and leave implementation empty for a few releases. * libinterp/corefcn/error.cc: Use different id for test. * examples/code/make_int.cc: No longer advertise "warn_divide_by_zero" in the examples. * libinterp/operators/op-*-*.cc: Remove unused header "errwarn.h". Remove check for scalar zero divisor including the warning. * libinterp/operators/op-dms-template.cc (gripe_if_zero): Remove function. * scripts/general/quadgk.m, scripts/general/quadv.m, scripts/statistics/kurtosis.m, scripts/statistics/mean.m, scripts/statistics/skewness.m: No longer need to turn off unused warning. * scripts/help/warning_ids.m: Remove documentation of "Octave:divide-by-zero". * test/jit.tst, test/mk-sparse-tst.sh, test/prefer.tst: Remove warning "Octave:divide-by-zero".
