103ed08549 Implement legacy OCSP APIs for libssl.
Previously, we'd omitted OpenSSL's OCSP APIs because they depend on a
complex OCSP mechanism and encourage the the unreliable server behavior
that hampers using OCSP stapling to fix revocation today. (OCSP
responses should not be fetched on-demand on a callback. They should be
managed like other server credentials and refreshed eagerly, so
temporary CA outage does not translate to loss of OCSP.)

But most of the APIs are byte-oriented anyway, so they're easy to
support. Intentionally omit the one that takes a bunch of OCSP_RESPIDs.

The callback is benign on the client (an artifact of OpenSSL reading
OCSP and verifying certificates in the wrong order). On the server, it
encourages unreliability, but pyOpenSSL/cryptography.io depends on this.
Dcument that this is only for compatibility with legacy software.

Also tweak a few things for compatilibility. cryptography.io expects
SSL_CTX_set_read_ahead to return something, SSL_get_server_tmp_key's
signature was wrong, and cryptography.io tries to redefine
SSL_get_server_tmp_key if SSL_CTRL_GET_SERVER_TMP_KEY is missing.

e28552dec8 Add an API to disable RSA-PSS for certificates.
Chrome uses the platform certificate verifier and thus cannot reliably
expect PSS signatures to work in all configurations. Add an API for the
consumer to inform BoringSSL of this ability. We will then adjust our
advertisements accordingly.

Note that, because TLS 1.2 does not have the signature_algorithms_cert
extension, turning off TLS 1.3 and using this API will stop advertising
RSA-PSS. I believe this is the correct behavior given the semantics of
that code point.

The tests check the various combinations here, as well as checking that
the peer never sends signature_algorithms_cert identical to
signature_algorithms.

512a289a8a Add support for dummy PQ padding.
This extension will be used to measure the latency impact of potentially
sending a post-quantum key share by default. At this time it's purely
measuring the impact of the client sending the key share, not the server
replying with a ciphertext.

We could use the existing padding extension for this but that extension
doesn't allow the server to echo it, so we would need a different
extension in the future anyway. Thus we just create one now.

We can assume that modern clients will be using TLS 1.3 by the time that
PQ key-exchange is established and thus the key share will be sent in
all ClientHello messages. However, since TLS 1.3 isn't quite here yet,
this extension is also sent for TLS 1.0–1.2 ClientHellos. The latency
impact should be the same either way.

RSA-PSS with SHA-512 is actually too large for 1024-bit RSA. Also make

the ecdsa_sha1 TLS 1.3 test.

For now, RSA-PKCS1 is still allowed because NSS has yet to implement
RSA-PSS and we'd like to avoid complicated interop testing.

025638597a Changing representation of signature/hash to use SignatureScheme.
As part of the SignatureAlgorithm change in the TLS 1.3 specification,
the existing signature/hash combinations are replaced with a combined
signature algorithm identifier. This change maintains the existing APIs
while fixing the internal representations. The signing code currently
still treats the SignatureAlgorithm as a decomposed value, which will be
fixed as part of a separate CL.

This is easier to deploy, and more obvious.  This commit reverts a few
pieces of e25775bc, but keeps most of it.

ce902a9bcd Generalizing curves to groups in preparation for TLS 1.3.
The 'elliptic_curves' extension is being renamed to 'supported_groups'
in the TLS 1.3 draft, and most of the curve-specific methods are
generalized to groups/group IDs.

13414b3a04 Implement draft-ietf-tls-chacha20-poly1305-04.
Only ECDHE-based ciphers are implemented. To ease the transition, the
pre-standard cipher shares a name with the standard one. The cipher rule parser
is hacked up to match the name to both ciphers. From the perspective of the
cipher suite configuration language, there is only one cipher.

This does mean it is impossible to disable the old variant without a code
change, but this situation will be very short-lived, so this is fine.

Also take this opportunity to make the CK and TXT names align with convention.

87cfcdb6df Resolve another ChaCha20-Poly1305 rename deadlock.
WebRTC can't roll into Chromium without picking up the iOS build fix, but we
can't roll BoringSSL forwards because WebRTC also depends on the previously
exposed ChaCha20-Poly1305 cipher suite constants.

Define the old constants again.

271777f5ac Refactor ChaCha20-Poly1305 AEAD nonce handling.
This change reduces unnecessary copying and makes the pre-RFC-7539
nonces 96 bits just like the AES-GCM, AES-CCM, and RFC 7539
ChaCha20-Poly1305 cipher suites. Also, all the symbols related to
the pre-RFC-7539 cipher suites now have "_OLD" appended, in
preparation for adding the RFC 7539 variants.

07e138425d Move remaining functions out of tls1.h.
Now tls1.h is just a pile of protocol constants with no more circular
dependency problem.

I've preserved SSL_get_servername's behavior where it's simultaneously a
lookup of handshake state and local configuration.  I've removed it from
SSL_get_servername_type. It got the logic wrong anyway with the order of
the s->session check.

(Searching through code, neither is used on the client, but the
SSL_get_servername one is easy.)
