Backed out changeset 938794bc82b7 Renaming octave_base_value::count to m_count breaks some packages that define new octave_value data types. Maybe those packages shouldn't be touching the count directly, but they do. Since we may also want to switch to using std::shared_ptr to manage octave_value objects instead of our own custom reference counting implmentation, it is probably best to delay this change until we know exactly what path we want to take.
