    Merge branch 'tkm-sig'

    Adds support for signature authentication (the exception is RSA-PSS,
    the focus in the TKM is generally on ECC) and makes the arguments for
    signature verification and creation symmetrical (previously, the whole
    AUTH payload data was passed when verifying, now only the actual
    signature).  Also changes some other things in the interface (adds ISA
    flags and uses blobs to pass IKE_SA_INIT messages in preparation for the
    downgrade-prevention changes).
