In order to support 64 bits byte count, which does not fit in the space reverse for them in the stream (4 bytes minus 3 control bits) and the position and some byte count do not fit in the variable used in existing code (arguments to WriteVersion, SetByteCount, ReadVersion and CheckByteCount), we need to pass them indirectly. Since the streaming is inherently serial, we can leverage the sequence of calls and cache the 64 bits values in a queue. The bytecount that can not be stored in place in the stream will be held in a collection (fByteCounts) that need to be stored externally to the buffer.
