A couple new io buffers that encapsulate more data and are therefore easier to use and easier to reason about. Inspired by RequestHeaders and ResponseHeaders in http_network_transaction.h Separated out of the refactoring of HttpNetworkTransaction to support pipelining. (http://codereview.chromium.org/249031)
