Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

This patch replaces the seqniv generator with seqiv when the
underlying algorithm understands the new calling convention.

This not only makes more sense as now seqiv is solely responsible
for IV generation rather than also determining how the IV is going
to be used, it also allows for optimisations in the underlying
implementation.  For example, the space for the IV could be used
to add padding for authentication.

This patch also removes the unnecessary copying of IV to dst
during seqiv decryption as the IV is part of the AD and not cipher
text.
Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

This patch fixes a bug where we were incorrectly including the
IV in the AD during encryption.  The IV must remain in the plain
text for it to be encrypted.

During decryption there is no need to copy the IV to dst because
it's now part of the AD.

This patch removes an unncessary check on authsize which would be
performed by the underlying decrypt call.

Finally this patch makes use of the type-safe init/exit functions.

This patch adds a type-safe function for freeing AEAD instances

instance that it's freeing.
Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

Currently the task of freeing an instance is given to the crypto
template.  However, it has no type information on the instance so
we have to resort to checking type information at runtime.

This patch introduces a free function to crypto_type that will be
used to free an instance.  This can then be used to free an instance
in a type-safe manner.

This patch fixes a host of reentrancy bugs in the nx driver.  The
following algorithms are affected:

* CCM
* GCM
* CTR
* XCBC
* SHA256
* SHA512

The crypto API allows a single transform to be used by multiple
threads simultaneously.  For example, IPsec will use a single tfm
to process packets for a given SA.  As packets may arrive on
multiple CPUs that tfm must be reentrant.

The nx driver does try to deal with this by using a spin lock.
Unfortunately only the basic AES/CBC/ECB algorithms do this in
the correct way.

The symptom of these bugs may range from the generation of incorrect
output to memory corruption.
