This implements the state changes for the wimax devices. It will
</p><p>
- verify that the state transition is legal (for now it'll just
print a warning if not) according to the table in
linux/wimax.h's documentation for 'enum wimax_st'.
</p><p>
- perform the actions needed for leaving the current state and
whichever are needed for entering the new state.
</p><p>
- issue a report to user space indicating the new state (and an
optional payload with information about the new state).
