Ard Biesheuvel	9ae433bc79	crypto: chacha20 - convert generic and x86 versions to skcipher This converts the ChaCha20 code from a blkcipher to a skcipher, which is now the preferred way to implement symmetric block and stream ciphers. This ports the generic and x86 versions at the same time because the latter reuses routines of the former. Note that the skcipher_walk() API guarantees that all presented blocks except the final one are a multiple of the chunk size, so we can simplify the encrypt() routine somewhat.

crypto: chacha20 - convert generic and x86 versions to skcipher

This converts the ChaCha20 code from a blkcipher to a skcipher, which
is now the preferred way to implement symmetric block and stream ciphers.

This ports the generic and x86 versions at the same time because the
latter reuses routines of the former.

Note that the skcipher_walk() API guarantees that all presented blocks
except the final one are a multiple of the chunk size, so we can simplify
the encrypt() routine somewhat.

The CRNG is faster, and we don't pretend to track entropy usage in the
CRNG any more.

crypto: chacha20 - Export common ChaCha20 helpers

As architecture specific drivers need a software fallback, export a
ChaCha20 en-/decryption function together with some helpers in a header
file.
