This patch is preparation for adding new algorithm types.

Some elements which are AEAD specific were renamed.
The algorithm template structure was changed to
use crypto_alg, and talitos_alg_alloc was made
more general with respect to algorithm types.
ipsec_esp_edesc is renamed to talitos_edesc
to use it in the upcoming ablkcipher routines.
