[evolution-data-server/639605-google-contacts-async: 2/15] Rebase the Google Contacts backend as an asynchronous EBookBackend

commit c115e6437c3be6f1eee76a2312eb1f513c61c682
Author: Philip Withnall <philip tecnocode co uk>
Date:   Sat Nov 20 17:37:07 2010 +0000

    Rebase the Google Contacts backend as an asynchronous EBookBackend
    
    None of the code takes advantage of this yet (it is all still synchronous),
    but the backend no longer depends on EBookBackendSync.
