AES-GCM should have a 12-byte nonce. However, non-standard nonce sizes
are defined by NIST and, although they are a bad idea, people have used
them because they've confused an IV with an nonce and passed in a
16-byte nonce.
This change adds a test for this.

Derived from upstream's new evp_test. The tests were taken from upstream
but tweaked so the diff from the old cipher_test.txt is more obvious.

I tried so hard to get rid of AES-192, but it's called from too many
places. I suspect that those places don't actually use it, but it's
dangerous to assume that.

Test that SSLv3 accepts arbitrary padding bytes (hello, POODLE) and rejects
non-minimal padding, while TLS accepts non-minimal padding but rejects
arbitrary padding bytes.
Also test what happens when the MAC is correct, but there is no padding. This
is the case that triggers a failing padding_ok check after the MAC check
on padding_len = 0 passes.

This introduces another knob into SSL_AEAD_CTX to omit the version from the ad
parameter. It also allows us to fold a few more SSL3_ENC_METHOD hooks together.

The EVP_CIPHER codepath should no longer be used with TLS. It still exists for
DTLS and SSLv3. The AEAD construction in TLS does not allow for
variable-overhead AEADs, so stateful AEADs do not include the length in the ad
parameter. Rather the AEADs internally append the unpadded length once it is
known. EVP_aead_rc4_md5_tls is modified to account for this.
Tests are added (and RC4-MD5's regenerated) for each of the new AEADs. The
cipher tests are all moved into crypto/cipher/test because there's now a lot of
them and they clutter the directory listing.
In ssl/, the stateful AEAD logic is also modified to account for stateful AEADs
with a fixed IV component, and for AEADs which use a random nonce (for the
explicit-IV CBC mode ciphers).
The new implementation fixes a bug/quirk in stateless CBC mode ciphers where
the fixed IV portion of the keyblock was generated regardless. This is at the
end, so it's only relevant for EAP-TLS which generates a MSK from the end of
the key block.
