Implementation of streambuf for use by the Buffer's ostream.
This class derives from std::streambuf and implements the virtual functions needed to operate on OutputBuffer. The override functions are overflow and xsputn. Typically custom streambufs will also override sync for output, but we have no need since all writes are immediately stored in the buffer.
