    kernel: use kernel_route_from_spd() to fix up addressses before calling eroute_connection()

    kernel: add kernel_route_from_spd(spd, mode, direction)
    
    lift code out of setup_half_ipsec_sa() that deals with
    transport mode and l2tp.

    kernel: struct encap_rules -> struct kernel_encap
    
    so it is clearer that this is part of the kernel interface
    
    also change <<bool .tunnel>> to <<enum encap_mode .mode>>; changing:
       if (!encap.tunnel)
    to the hopefully more readable:
       if (encap.mode == ENCAP_MODE_TRANSPORT)
    don't use ENCAPSULATION_MODE_* enum as that sucks in all sorts of
    useless stuff.
