update out_of_range error messages * sub2ind.cc (Fsub2ind): Don't redimension dim_vector object so that the sub2ind function may report original dimensions in error messages. * Range.h (Range::dims): New function. * lo-array-errwarn.h, lo-array-errwarn.cc (out_of_range::set_size, out_of_range::set_extent): Delete. (out_of_range::out_of_range): Accept size and extent arguments. (out_of_range::details): Simplify. Always report extent and dimensions. (err_index_out_of_range): Deprecate overload that does not accept dim_vector argument. Change all uses to call the one that does. Simplify by passing extent and dims to out_of_range_object constructor. * test/index.tst: Update error messages in tests.
