Eelco Chaudron ef557e2c55 utilities: Add the ovs_show_fdb command to gdb ...

This adds the ovs_show_fdb command:

  Usage: ovs_show_fdb {<bridge_name> {dbg} {hash}}

  <bridge_name> : Optional bridge name, if not supplied FDB summary
                  information is displayed for all bridges.
  dbg           : Will show structure address information
  hash          : Will display the forwarding table using the hash
                  table, rather than the rlu list.

Some examples:

  (gdb) ovs_show_fdb

      table.n         : 0
