    Removed eval of unchecked strings.

     * eval() was previously used to marshall unchecked strings as
       filter parameters for QuantumDbPluginV2.get_ports() via
       the --fixed_ips flag.
     * This change removes the use of eval and cleans up the filtering
       implementation for get_ports().
     * The new filtering implementation does not support arbitrary
       OR'ing or AND'ing. Instead, multiple values for a given filter
       key are logically OR'ed, and filters across keys are AND'ed.
     * Example usage - filter for .2 or .3 in the given subnet:

         quantum port-list -- --fixed_ips ip_address=10.0.0.3 \
             ip_address=10.0.0.2 subnet_id=nOtaRealId

     * Addresses bug 1052179
