20c373118c Become partially -Wmissing-variable-declarations-clean.
There's a few things that will be kind of a nuisance and possibly not worth it
(crypto/asn1 dumps a lot of undeclared things, etc.). But it caught some
mistakes. Even without the warning, making sure to include the externs before
defining a function helps catch type mismatches.

21cdada609 Fix warning about unused |EVP_PKEY_METHOD.ctrl_str|.
Some compilers in some configurations warn about this structure member
not being assigned a value. Since it is never used anywhere, just
remove it.

74f711083d Parse RSAPrivateKey with CBS.
This removes the version field from RSA and instead handles versioning
as part of parsing. (As a bonus, we now correctly limit multi-prime RSA
to version 1 keys.)

Most consumers are also converted. old_rsa_priv_{de,en}code are left
alone for now. Those hooks are passed in parameters which match the old
d2i/i2d pattern (they're only used in d2i_PrivateKey and
i2d_PrivateKey).

Include a test which, among other things, checks that public keys being
serialized as private keys are handled properly.

65ee9b7ce9 Remove EVP_PKEY_HMAC.
This removes EVP_PKEY_HMAC and all the support code around it. EVP_MD requires
a lot of extra glue to support HMAC. This lets us prune it all away.

As a bonus, it removes a (minor) dependency from EVP to the legacy ASN.1 stack.

e0ba4dddf6 Normalize all EVP_PKEY_CTX_ctrl return values.
No code within BoringSSL or Google (grep for EVP_PKEY_CTX_(ctrl|get|set)) is
sensitive to the various failure cases. Normalize it all to 0/1 for simplicity.

This does carry a slight risk: any new ctrl hooks we import from upstream that,
like EVP_PKEY_CTX_get_rsa_oaep_md, return something other than success/failure
cannot be called directly via EVP_PKEY_CTX_ctrl. They instead need to
internally be routed through a struct like CBS and only called through the
wrappers. To that end, unexport EVP_PKEY_CTX_ctrl and require that callers use
the wrappers. No code in Google uses it directly and, if need be, switching to
the wrapper would be an incredibly upstreamable patch.

c20febe177 Add EVP_PKEY_supports_digest.
This is intended for TLS client auth with Windows CAPI- and CNG-backed keys
which implement sign over sign_raw and do not support all hash functions. Only
plumbed through RSA for now.

8cfd8ad144 Remove unused EVP_PKEY_ASN1_METHODs and flags.
The only alias, EVP_PKEY_RSA2, is handled programmatically. ASN1_PKEY_ALIAS and
ASN1_PKEY_DYNAMIC are then unused and unexported and can be removed.

8f160a680b Add EVP_DigestVerifyInitFromAlgorithm and EVP_DigestSignAlgorithm.
Factor the AlgorithmIdentifier portions of ASN1_item_sign and ASN1_item_verify
out. This makes it possible to initialize a signature context from an
AlgorithmIdentifier without needing the data parsed into an ASN1_ITEM/void*
pair and reserialized.

ecc0ce7e67 Introduce EVP_PKEY_is_opaque to replace RSA_METHOD_FLAG_NO_CHECK.
Custom RSA and ECDSA keys may not expose the key material. Plumb and "opaque"
bit out of the *_METHOD up to EVP_PKEY. Query that in ssl_rsa.c to skip the
sanity checks for certificate and key matching.

9b561e69b6 Fix EVP_PKEY_FLAG_AUTOARGLEN behavior.
Converting check_autoarg from a macro to a function lost the behavior. Instead,
just move the logic into p_rsa.c which was the only EVP_PKEY implementation
that even needed the flag.

Also document this behavior on each of the functions. Make note of the out =
NULL case only returning the maximum output size, and not necessarily the
actual size.

For testing, update example_sign to determine the signature size using the NULL
behavior rather than querying the RSA key.
