The context used to store the key blob used a fixed 80 bytes buffer. And all the set_key functions did not even check the given key size. With CCA variable length AES cipher keys there come key blobs with about 136 bytes and maybe in the future there will arise the need to store even bigger key blobs. This patch reworks the paes set_key functions and the context buffers to work with small key blobs (<= 128 bytes) directly in the context buffer and larger blobs by allocating additional memory and storing the pointer in the context buffer. If there has been memory allocated for storing a key blob, it also needs to be freed on release of the tfm. So all the paes ciphers now have a init and exit function implemented for this job.
