crypto: more self-test improvements

This series makes some more improvements to the crypto self-tests, the largest of which is making the AEAD fuzz tests test inauthentic inputs, i.e. cases where decryption is expected to fail due to the (ciphertext, AAD) pair not being the correct result of an encryption with the key.

It also updates the self-tests to test passing misaligned buffers to the various setkey() functions, and to check that skciphers have the same min_keysize as the corresponding generic implementation.

I haven't seen any test failures from this on x86_64, arm64, or arm32. But as usual I haven't tested drivers for crypto accelerators.

For this series to apply this cleanly, my other series "crypto: skcipher - simplifications due to {,a}blkcipher removal" needs to be applied first, due to a conflict in skcipher.h.

Eric Biggers (7):
crypto: aead - move crypto_aead_maxauthsize() to <crypto/aead.h>
crypto: skcipher - add crypto_skcipher_min_keysize()
crypto: testmgr - don't try to decrypt uninitialized buffers
crypto: testmgr - check skcipher min_keysize
crypto: testmgr - test setting misaligned keys
crypto: testmgr - create struct aead_extra_tests_ctx
crypto: testmgr - generate inauthentic AEAD test vectors
