[strongSwan] many cipher/hash modes seems to be unavailable

[Andreas Steffen]

Hi Chris,

IKEv2 support for the AEAD modes CCM and GCM will be introduced
with the forthcoming strongSwan release 4.5.0. Thus Debian sid
certainly does not support them. I you want to test IKEv2 AEAD,
please download the latest developers release

   http://download.strongswan.org/strongswan-4.5.0dr3.tar.bz2

Regards

Andreas
