Previously, error strings were kept in arrays for each subdirectory and
err.c would iterate over them all and insert them at init time to a hash
table.
This means that, even if you have a shared library and lots of processes
using that, each process has ~30KB of private memory from building that
hash table.
This this change, all the error strings are built into a sorted list and
are thus static data. This means that processes can share the error
information and it actually saves binary space because of all the
pointer overhead in the old scheme. Also it saves the time taken
building the hash table at startup.
This removes support for externally-supplied error string data.

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.

These helper functions will be used in the implementation of the legacy CBC
mode AEADs. The file is copied as-is and then modified to remove the dependency
on ssl/. Notably explicit IV logic is removed (that's a side effect of how
explicit IVs are currently implemented) and the padding length is returned
directly rather than smuggled into rec->type.
(Diffing tls_cbc.c and s3_cbc.c is probably the easiest for a review.)
The helpers are currently unused.

As useless as it might seem, the certificates in PKCS#12 files appear to
always be encrypted with 40-bit RC2. OpenSSL, NSS and Windows are all
the same on this point. Thus, in order to be able to import PKCS#12
files we need RC2 support.
RC2 has deliberately not been added to EVP_get_cipherbynid so that the
linker can drop the RC2 code unless the PKCS#12 functions are actually
called.

Initial fork from f2d678e6e89b6508147086610e985d4e8416e867 (1.0.2 beta).
(This change contains substantial changes from the original and
effectively starts a new history.)
