MessageBuffer.slice()

[xerial]

Current v07-draft branch uses limit() setLimit(...) methods to obtain the written data range. Instead, we should provide MessageBuffer slice(int offset, int len) method to make MessageBuffer immutable (except its memory contents).

I simply removed limit parameter from MessageBuffer, and provide slice() method. Memory management of generated slices need to be discussed in another ticket.
