stp: treat a link aggregation group as one entity

Browse Source 
Spanning tree so far saw only physical ports. Two ports aggregated towards
the same neighbour look to the protocol like two parallel paths, so it
blocks one of them and cuts the group in half.

Give each of the four groups an STP entity of its own, numbered above the
physical ports. A member port answers to its group: BPDUs arriving on it
are accounted to the entity, the entity's state is written to every member
together, and its BPDUs carry the state of a live member. Ports outside
any group keep behaving exactly as before.

Membership comes from the aggregation tables once a second; when it
changed, the entity's state is reapplied to the new set of members. The
CLI takes lag <1-4> wherever it takes port <n>, the web UI shows a group
as one row, and the saved config keeps the lag form of the commands.
