From cfdb9907cb87d15eaab72ceefbfa42fd7a4c3127 Mon Sep 17 00:00:00 2001
From: Josh Haberman <haberman@google.com>
Date: Sat, 11 May 2013 16:45:38 -0700
Subject: Synced with 3 months of Google-internal development.

Major changes:
- Got rid of all bytestream interfaces in favor of
  using regular handlers.
- new Pipeline object represents a upb pipeline, does
  bump allocation internally to manage memory.
- proto2 support now can handle extensions.
