Using |size_t| was correct, except for NaCl, which is a 64-bit build
with 32-bit pointers. In that configuration, |size_t| is smaller than
the native word size.
This change adds |crypto_word_t|, an unsigned type with native size and
switches constant-time functions to using it.

The changes to delocate.go are needed because modes/ does things like
return the address of a module function. Both of these need to be
changed from referencing the GOT to using local symbols.
Rather than testing whether |ghash| is |gcm_ghash_avx|, we can just keep
that information in a flag.
The test for |aesni_ctr32_encrypt_blocks| is more problematic, but I
believe that it's superfluous and can be dropped: if you passed in a
stream function that was semantically different from
|aesni_ctr32_encrypt_blocks| you would already have a bug because
|CRYPTO_gcm128_[en|de]crypt_ctr32| will handle a block at the end
themselves, and assume a big-endian, 32-bit counter anyway.

Not that this is remotely necessary since the code bounds to 1MB, the
caller bounds to INT_MAX (due to EVP_CIPHER) and the grandcaller bounds
to 16k (due to TLS).

The old one was rather confusing. Switch to returning 1/0 for whether
the padding is publicly invalid and then add an output argument which
returns a constant_time_eq-style boolean.

This function allows one to extract the current IVs from an SSL
connection. This is needed for the CBC cipher suites with implicit IVs
because, for those, the IV can't be extracted from the handshake key
material.

OpenSSH, especially, does some terrible things that mean that it needs
the EVP_CIPHER structure to be exposed ☹. Damian is open to a better API
to replace this, but only if OpenSSL agree too. Either way, it won't be
happening soon.

Beyond generally eliminating unnecessary includes, eliminate as many
includes of headers that declare/define particularly error-prone
functionality like strlen, malloc, and free. crypto/err/internal.h was
added to remove the dependency on openssl/thread.h from the public
openssl/err.h header. The include of <stdlib.h> in openssl/mem.h was
retained since it defines OPENSSL_malloc and friends as macros around
the stdlib.h functions. The public x509.h, x509v3.h, and ssl.h headers
were not changed in order to minimize breakage of source compatibility
with external code.

Instead, add a separate init_with_direction hook. Normal AEADs ignore the
direction, while legacy AEADs must be initialized with it. This avoids
maintaining extra state to support the delayed initialization.

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.
