Eric Biggers c9a3ff8f22 crypto: x86/salsa20 - cleanup and convert to skcipher API 
Convert salsa20-asm from the deprecated "blkcipher" API to the
"skcipher" API, in the process fixing it up to use the generic helpers.
This allows removing the salsa20_keysetup() and salsa20_ivsetup()
assembly functions, which aren't performance critical; the C versions do
just fine.

This also fixes the same bug that salsa20-generic had, where the state
array was being maintained directly in the transform context rather than
on the stack or in the request context.  Thus, if multiple threads used
the same Salsa20 transform concurrently they produced the wrong results.

This is a generic implementation of AES that attempts to eliminate
data dependent latencies as much as possible without affecting
performance too much. It is intended for use by the generic CCM
and GCM drivers, and other CTR or CMAC/XCBC based modes that rely
solely on encryption (although decryption is supported as well, but
with a more dramatic performance hit)
Instead of using 16 lookup tables of 1 KB each, (8 for encryption and
8 for decryption), this implementation only uses just two S-boxes of
256 bytes each, and attempts to eliminate data dependent latencies by
prefetching the entire table into the cache at the start of each
block.

The Jitterentropy RNG is a noise that is intended
to provide seed to another RNG. The RNG does not
perform any cryptographic whitening of the generated
random numbers. This Jitterentropy RNG registers with
the kernel crypto API and can be used by any caller.
