    The station change API isn't being checked properly before
    drivers are called, and as a result it is difficult to see
    what should be allowed and what not.
    
    In order to comprehensively check the API parameters parse
    everything first, and then have the driver call a function
    (cfg80211_check_station_change()) with the additionally
    information about the kind of station that is being changed;
    this allows the function to make better decisions than the
    old code could.
    
    While at it, also add a few checks, particularly in mesh
    and clarify the TDLS station lifetime in documentation.
    
    To be able to reduce a few checks, ignore any flag set bits
    when the mask isn't set, they shouldn't be applied then.
