    IKE SPI: replace get_cookie(bool,uint8_t*) with fill_ike_{initiator,responder}_spi(ike_sa,...)
    
    Uses IKEv2 names.  Split into explicit initiator/responder functions
    (don't rely on 'bool' and 'uint8_*' being correctly aligned).
    
    Uses a local secret_of_the_day; with size increased to match
    SHA2 algorithm.
    
    New code lives in ike_spi.[hc].  Bunch of unnecessary #includes
    deleted as a side effect.
    
    Also add, but don't yet use, zero_ike_spi, and ike_spi_is_zero().
