chunkbuffer: use += rather than cStringIO to reduce memory footprint

This significantly refactors the read() loop to use a queue of chunks.
The queue is alternately filled to at least 256k and then emptied by
concatenating onto the output buffer.

For very large read sizes, += uses less memory because it can resize
the target string in place.
