[evolution-data-server/openismus-work] Add E_BOOK_SDB_ERROR_INVALID_QUERY



commit 2704d71dc2d521158d0a13336b417e3960785af3
Author: Tristan Van Berkom <tristanvb openismus com>
Date:   Wed Feb 27 20:02:08 2013 +0900

    Add E_BOOK_SDB_ERROR_INVALID_QUERY
    
    The invalid query is reported for queries where e_sexp_parse() fails,
    or for any queries of the E_BOOK_QUERY_EQUALS_*_PHONE_NUMBER type
    where the query term is not a recognized phone number.
    
    Additionally, this patch removes the g_warnings() fired when
    invalid phone number values are added to the summary columns
    indexed with the E_BOOK_INDEX_PHONE index type (since it's a
    perfectly normal use case to set invalid phone number values in
    contact phone number fields, we don't want warnings printed
    for that).
