Initial commit of sync engine code to browser/sync.

The code is not built on any platform yet.  That will arrive
as a subsequent checkin.

This is an implementation of the interface exposed earlier
through syncapi.h.  It is the client side of a sync
protocol that lets users sync their browser data
(currently, just bookmarks) with their Google Account.

Table of contents:

browser/sync/
  protocol - The protocol definition, and
             other definitions necessary to connect to
             the service.
  syncable/ - defines a data model for syncable objects,
              and provides a sqlite-based backing store
              for this model.
  engine/ - includes the core sync logic, including commiting
            changes to the server, downloading changes from
            the server, resolving conflicts, other parts of
            the sync algorithm.
  engine/net - parts of the sync engine focused on the
               business of talking to the server.  Some of
               this is binds a generic "server connection"
               interface to a concrete implementation
               provided by Chromium.
  notifier - the part of the syncer focused on the business
             of sending and receiving xmpp notifications.
             Notifications are used instead of polling to
             achieve very low latency change propagation.
  util - not necessarily sync specific utility code.  Much
         of this is scaffolding which should either be
         replaced by, or merged with, the utility code
         in base/.

BUG=none
TEST=this code includes its own suite of unit tests.
