This patch is the first step in the introduction of a new AEAD
alg type.  Unlike normal conversions this patch only renames the
existing aead_alg structure because there are external references
to it.

Those references will be removed after this patch.

The primary user of AEAD, IPsec includes the IV in the AD in
most cases, except where it is implicitly authenticated by the
underlying algorithm.

The way it is currently implemented is a hack because we pass
the data in piecemeal and the underlying algorithms try to stitch
them back up into one piece.

This is why this patch is adding a new interface that allows a
single SG list to be passed in that contains everything so the
algorithm implementors do not have to stitch.

The new interface accepts a single source SG list and a single
destination SG list.  Both must be laid out as follows:

	AD, skipped data, plain/cipher text, ICV

The ICV is not present from the source during encryption and from
the destination during decryption.

For the top-level IPsec AEAD algorithm the plain/cipher text will
contain the generated (or received) IV.

This patch adds the scatterwalk_ffwd helper which can create an
SG list that starts in the middle of an existing SG list.  The
new list may either be part of the existing list or be a chain
that latches onto part of the existing list.

As AEAD has switched over to using frontend types, the function
crypto_init_spawn must not be used since it does not specify a
frontend type.  Otherwise it leads to a crash when the spawn is
used.

This patch fixes it by switching over to crypto_grab_aead instead.

-change req_ctx->nbuf from u64 to unsigned int to silence checker
warnings; this is safe since nbuf value is <= HASH_MAX_BLOCK_SIZE
-remove unused value read from TALITOS_CCPSR; there is no requirement
to read upper 32b before reading lower 32b of a 64b register;
SEC RM mentions: "reads can always be done by byte, word, or dword"
-remove unused return value of sg_to_link_tbl()

This reverts commit 7291a932.

The conversion to be16_add_cpu() is incorrect in case cryptlen is
negative due to premature (i.e. before addition / subtraction)
implicit conversion of cryptlen (int -> u16) leading to sign loss.

The allocation/free functions have switched over to the new way of
allocating tfms.
