radius: Add tagged VLAN parsing

Browse source 
1. Add tagged VLAN to struct vlan_description
    (compile limited number of tagged VLANs per description)
    For k tagged VLANs, the first k entries in vlan_description.tagged
    are used. They are sorted in ascending order. All other entries are
    zero. This way os_memcmp() can find identical configurations.
2. Let tagged VLANs be parsed from RADIUS Access-Accept
3. Print VLAN %d+ with %d=untagged VID if tagged VLANs are set
4. Select an unused vlan_id > 4096 for new tagged VLAN configurations
5. Add EGRESS_VLAN RADIUS attribute parsing also for untagged VLANs
