There are no users of the original glue_fpu_begin() anymore, so rename
glue_skwalk_fpu_begin() to glue_fpu_begin() so that it matches
glue_fpu_end() again.

Now that all glue_helper users have been switched from the blkcipher
interface over to the skcipher interface, remove the versions of the
glue_helper functions that handled the blkcipher interface.

Now that all users of lrw_crypt() have been removed in favor of the LRW
template wrapping an ECB mode algorithm, remove lrw_crypt(). Also
remove crypto/lrw.h as that is no longer needed either; and fold
'struct lrw_table_ctx' into 'struct priv', lrw_init_table() into
setkey(), and lrw_free_table() into exit_tfm().

Add ECB, CBC, and CTR functions to glue_helper which use skcipher_walk
rather than blkcipher_walk. This will allow converting the remaining
x86 algorithms from the blkcipher interface over to the skcipher
interface, after which we'll be able to remove the blkcipher_walk
versions of these functions.

We checked (nbytes < bsize) inside the loops so it's not possible to hit
the "goto done;" here. This code is cut and paste from other slightly
different loops where we don't have the check inside the loop.

The le128_gf128mul_x_ble function in glue_helper.h is now obsolete and
can be replaced with the gf128mul_x_ble function from gf128mul.h.

This patch adds xts helpers that use the skcipher interface rather
than blkcipher. This will be used by aesni_intel.

This patch adds AVX optimized XTS-mode helper functions/macros and converts
serpent-avx to use the new facilities. Benefits are slightly improved speed
and reduced stack usage as use of temporary IV-array is avoided.

'u128' currently used for CTR mode is on little-endian 'long long' swapped
and would require extra swap operations by SSE/AVX code. Use of le128
instead of u128 allows IV calculations to be done with vector registers
easier.

Glue_helper incorrectly XORs new IV over old IV at end of CBC encryption
function when it should store. This causes CBC encryption to give
incorrect output on multi-page encryption requests.
