[evolution-data-server] Restore e_flag_timed_wait().

[Matthew Barnes <mbarnes src gnome org>]

    Restore e_flag_timed_wait().
    
    Just deprecate the function, don't delete it.  GTimeVal isn't going
    away any time soon.  It's not worth a libedataserver soname bump.

+ * e_flag_timed_wait:

+ * If @flag is already set, the function returns immediately.  The return
+ * value indicates the state of @flag after waiting.

+ * If @abs_time is %NULL, e_flag_timed_wait() acts like e_flag_wait().

+ * To easily calculate @abs_time, a combination of g_get_current_time() and

+ * Returns: %TRUE if @flag is now set
