Pull EVP_PKEY print hooks out of the main method table. This allows the static linker to drop it in consumers which don't need this stuff (i.e. all sane ones), once crypto/x509 falls off. This cuts down on a number of dependencies from the core crypto bits on crypto/asn1 and crypto/x509.

Implement new SPKI parsers. Many consumers need SPKI support (X.509, TLS, QUIC, WebCrypto), each with different ways to set signature parameters. SPKIs themselves can get complex with id-RSASSA-PSS keys which come with various constraints in the key parameters. This suggests we want a common in-library representation of an SPKI. This adds two new functions EVP_parse_public_key and EVP_marshal_public_key which converts EVP_PKEY to and from SPKI and implements X509_PUBKEY functions with them. EVP_PKEY seems to have been intended to be able to express the supported SPKI types with full-fidelity, so these APIs will continue this. This means future support for id-RSASSA-PSS would *not* repurpose EVP_PKEY_RSA. I'm worried about code assuming EVP_PKEY_RSA implies acting on the RSA* is legal. Instead, it'd add an EVP_PKEY_RSA_PSS and the data pointer would be some (exposed, so the caller may still check key size, etc.) RSA_PSS_KEY struct. Internally, the EVP_PKEY_CTX implementation would enforce the key constraints. If RSA_PSS_KEY would later need its own API, that code would move there, but that seems unlikely. Ideally we'd have a 1:1 correspondence with key OID, although we may have to fudge things if mistakes happen in standardization. (Whether or not X.509 reuses id-ecPublicKey for Ed25519, we'll give it a separate EVP_PKEY type.) DSA parsing hooks are still implemented, missing parameters and all for now. This isn't any worse than before. Decoupling from the giant crypto/obj OID table will be a later task.

Implement new PKCS#8 parsers. As with SPKI parsers, the intent is make EVP_PKEY capture the key's constraints in full fidelity, so we'd have to add new types or store the information in the underlying key object if people introduce variant key types with weird constraints on them. Note that because PKCS#8 has a space for arbitrary attributes, this parser must admit a hole. I'm assuming for now that we don't need an API that enforces no attributes and just ignore trailing data in the structure for simplicity.

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.

Tweaks for node.js node.js is, effectively, another bindings library. However, it's better written than most and, with these changes, only a couple of tiny fixes are needed in node.js. Some of these changes are a little depressing however so we'll need to push node.js to use APIs where possible. Changes: ∙ Support verify_recover. This is very obscure and the motivation appears to be https://github.com/nodejs/node/issues/477 – where it's not clear that anyone understands what it means :( ∙ Add a few, no-op #defines ∙ Add some members to |SSL_CTX| and |SSL| – node.js needs to not reach into these structs in the future. ∙ Add EC_get_builtin_curves. ∙ Add EVP_[CIPHER|MD]_do_all_sorted – these functions are limited to decrepit.

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.

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.
