The link FSM implementation is currently unnecessarily complex. It sometimes checks for conditional state outside the FSM data before deciding next state, and often performs actions directly inside the FSM logics. In this commit, we create a second, simpler FSM implementation, that as far as possible acts only on states and events that it is strictly defined for, and postpone any actions until it is finished with its decisions. It also returns an event flag field and an a buffer queue which may potentially contain a protocol message to be sent by the caller. Unfortunately, we cannot yet make the FSM "clean", in the sense that its decisions are only based on FSM state and event, and that state changes happen only here. That will have to wait until the activate/reset logics has been cleaned up in a future commit. We also rename the link states as follows: WORKING_WORKING -> TIPC_LINK_WORKING WORKING_UNKNOWN -> TIPC_LINK_PROBING RESET_UNKNOWN -> TIPC_LINK_RESETTING RESET_RESET -> TIPC_LINK_ESTABLISHING The existing FSM function, link_state_event(), is still needed for a while, so we redesign it to make use of the new function.
