New style AEAD instances must use aead_register_instance. This
worked by chance because aead_geniv_alloc is still setting things
the old way.
This patch converts the template over to the create model where
we are responsible for instance registration so that we can call
the correct function.

This patch adds a new AEAD IV generator echainiv. It is intended
to replace the existing skcipher IV generator eseqiv.
If the underlying AEAD algorithm is using the old AEAD interface,
then echainiv will simply use its IV generator.
Otherwise, echainiv will encrypt a counter just like eseqiv but
it'll first xor it against a previously stored IV similar to
chainiv.
