Refactor HttpBasicStream to store data in HttpBasicState

In preparation for WebSocketBasicHandshakeStream, factor out common member
variables and functionality to a new HttpBasicState class.

See design doc at
https://docs.google.com/a/google.com/document/d/1AH2lRR2i2Wf4yODgckgdsvZeuGwpbvsvMGLnAMUXUbM/edit
and the WebSocketBasicHandshakeStream implementation CL at
https://codereview.chromium.org/25417005/

BUG=303568
TEST=net_unittests --gtest_filter=HttpBasicState*
