[PATCH crypto-next 00/23] crypto: skcipher - Remove VLA usage

[Kees Cook]

This is the full follow-up to earlier discussions[1] that suggested
adding a new struct crypto_sync_skcipher to handle the VLA removal from
SKCIPHER_REQUEST_ON_STACK.

This series is effectively a no-op change: everything is a wrapper
around struct crypto_skcipher, but provides compile-time enforcement
for not putting an ASYNC skcipher on the stack, which allows us to
declare the on-stack requests with a fixed stack size.
