    PPP, MPPE, discard late packet in stateless mode
    
    When PPP is used over a link which does not guarantee packet ordering,
    we might get late MPPE packets. This is a problem because MPPE must be
    kept synchronized and the current implementation does not drop them and
    rekey 4095 times instead of 0, which is wrong.
    
    In order to prevent rekeying about a whole count space times (~ 4095
    times), drop packets which are not within the forward 4096/2 window and
    increase sanity error counter.

    PPP, MPPE, sanity error path rework
    
    We are going to need sanity error path a little further, rework to be
    able to use the sanity error path anywhere in decompressor.
