Move fetching of full-fledged auth cookies to a time when we have the user's real profile available. Also, enable the use of a localaccount on Chrome OS

many of the changes here are just callsite fixes, because I changed the signature of a function.  I also moved my code into the chromeos namespace, which accounts for several other files.  The important stuff is in:

1) google_authenticator*
2) cookie_fetcher*
3) login_utils.cc
