Jon Paul Maloy 66996b6c47 tipc: extend node FSM
In the next commit, we will move link synch/failover orchestration to
the link aggregation level. In order to do this, we first need to extend
the node FSM with two more states, NODE_SYNCHING and NODE_FAILINGOVER,
plus four new events to enter and leave those states.

This commit introduces this change, without yet making use of it.
The node FSM now looks as follows:

                           +-----------------------------------------+
