crypto: skcipher - Introduce crypto_sync_skcipher
In preparation for removal of VLAs due to skcipher requests on the stack
via SKCIPHER_REQUEST_ON_STACK() usage, this introduces the infrastructure
for the "sync skcipher" tfm, which is for handling the on-stack cases of
skcipher, which are always non-ASYNC and have a known limited request
size.
The crypto API additions:
struct crypto_sync_skcipher (wrapper for struct crypto_skcipher)
crypto_alloc_sync_skcipher()
crypto_free_sync_skcipher()
crypto_sync_skcipher_setkey()
crypto_sync_skcipher_get_flags()
crypto_sync_skcipher_set_flags()
crypto_sync_skcipher_clear_flags()
crypto_sync_skcipher_blocksize()
crypto_sync_skcipher_ivsize()
crypto_sync_skcipher_reqtfm()
skcipher_request_set_sync_tfm()
SYNC_SKCIPHER_REQUEST_ON_STACK() (with tfm type check)
