crypto: skcipher - Make skcipher_walk src.virt.addr const

Mark the src.virt.addr field in struct skcipher_walk as a pointer
to const data. This guarantees that the user won't modify the data
which should be done through dst.virt.addr to ensure that flushing
is done when necessary.

crypto: ctr - add helper for performing a CTR encryption walk

Add a static inline helper modeled after crypto_cbc_encrypt_walk()
that can be reused for SIMD algorithms that need to implement a
non-SIMD fallback for performing CTR encryption.

[CRYPTO] ctr: Refactor into ctr and rfc3686

As discussed previously, this patch moves the basic CTR functionality
into a chainable algorithm called ctr. The IPsec-specific variant of
it is now placed on top with the name rfc3686.

So ctr(aes) gives a chainable cipher with IV size 16 while the IPsec
variant will be called rfc3686(ctr(aes)). This patch also adjusts
gcm accordingly.
