The hash_accept call fails to work on sockets that have not received
any data. For some algorithm implementations it may cause crashes.
This patch fixes this by ensuring that we only export and import on
sockets that have received data.

Merge the type-specific data with the payload data into one four-word chunk
as it seems pointless to keep them separate.
Use user_key_payload() for accessing the payloads of overloaded
user-defined keys.

x509_get_sig_params() has the same code pattern as the one in
pkcs7_verify() that is fixed by commit d71dd976730e ("crypto: pkcs7 - Fix
unaligned access in pkcs7_verify()") so apply a similar fix here: make
sure that desc is pointing at an algined value past the digest_size,
and take alignment values into consideration when doing kzalloc()

Don't #include crypto/public_key.h in akcipher as the contents of the
header aren't used and changes in a future patch cause it to fail to
compile if CONFIG_KEYS=n.

Currently a number of Crypto API operations may fail when a signal
occurs. This causes nasty problems as the caller of those operations
are often not in a good position to restart the operation.
In fact there is currently no need for those operations to be
interrupted by user signals at all. All we need is for them to
be killable.
This patch replaces the relevant calls of signal_pending with
fatal_signal_pending, and wait_for_completion_interruptible with
wait_for_completion_killable, respectively.

The testmanager code for symmetric ciphers is extended to allow
verification of the IV after a cipher operation.
In addition, test vectors for kw(aes) for encryption and decryption are
added.
