[evolution-data-server/openismus-work-master: 7/9] Make local addressbook backend store image data as URIs.

commit 614af51013f3945c41936af9972261dde3902802
Author: Tristan Van Berkom <tristan van berkom gmail com>
Date:   Fri Jul 22 20:05:21 2011 -0400

    Make local addressbook backend store image data as URIs.
    
    Whenever the local address book receives a uri as a binary
    blob it proceeds to transform it to a uri accessbile on
    the system somewhere under $XDG_DATA_HOME. The local backend
    cleans up old photo uris when contacts are removed or modified
    to use new photos.
    
    Additionally, whenever it is detected that the user is
    cross-referencing a uri which belongs to another contact,
    a hard-link will be created to the addressbook owned file
    on disk and a new uri will be assigned to any additional
    contacts which try to share a uri owned by the addressbook.
