net: bridge: vlan: add rtm range support
Add a new vlandb nl attribute - BRIDGE_VLANDB_ENTRY_RANGE which causes RTM_NEWVLAN/DELVAN to act on a range. Dumps now automatically compress similar vlans into ranges. This will be also used when per-vlan options are introduced and vlans' options match, they will be put into a single range which is encapsulated in one netlink attribute. We need to run similar checks as br_process_vlan_info() does because these ranges will be used for options setting and they'll be able to skip br_process_vlan_info().
