This currently only works for certificates parsed from the network, but
if making several connections that share certificates, some KB of memory

e8509090cf Hold certificates in an SSL_SESSION as CRYPTO_BUFFERSs as well.
This change adds a STACK_OF(CRYPTO_BUFFER) to an SSL_SESSION which
contains the raw form of the received certificates. The X509-based
members still exist, but their |enc| buffer will alias the
CRYPTO_BUFFERs.

The serialisation format of SSL_SESSIONs is also changed, in a backwards
compatible way. Previously, some sessions would duplicate the leaf
certificate in the certificate chain. These sessions can still be read,
but will be written in a way incompatible with older versions of the
code. This should be fine because the situation where multiple versions
exchange serialised sessions is at the server, and the server doesn't
duplicate the leaf certifiate in the chain anyway.

f5b30cc28c Add a simplified SSL BIO for curl.
A recent change to curl[1] added support for HTTPS proxies, which
involves running a TLS connection inside another TLS connection. This
was done by using SSL BIOs, which we removed from BoringSSL for being
crazy.

This change adds a stripped-down version of the SSL BIO to decrepit in
order to suport curl.

559f0644a5 Support setting per-connection OCSP staple
Right now the only way to set an OCSP response is SSL_CTX_set_ocsp_response
however this assumes that all the SSLs generated from a SSL_CTX share the
same OCSP response, which is wrong.

This is similar to the OpenSSL "function" SSL_get_tlsext_status_ocsp_resp,
the main difference being that this doesn't take ownership of the OCSP buffer.

In order to avoid memory duplication in case SSL_CTX has its own response,
a CRYPTO_BUFFER is used for both SSL_CTX and SSL.

ce8c9d2b41 Maintain SSL_HANDSHAKE lifetime outside of handshake_func.
We currently look up SSL_HANDSHAKE off of ssl->s3->hs everywhere, but
this is a little dangerous. Unlike ssl->s3->tmp, ssl->s3->hs may not be
present. Right now we just know not to call some functions outside the
handshake.

Instead, code which expects to only be called during a handshake should
take an explicit SSL_HANDSHAKE * parameter and can assume it non-NULL.
This replaces the SSL * parameter. Instead, that is looked up from
hs->ssl.

Code which is called in both cases, reads from ssl->s3->hs. Ultimately,
we should get to the point that all direct access of ssl->s3->hs needs
to be NULL-checked.

As a start, manage the lifetime of the ssl->s3->hs in SSL_do_handshake.
This allows the top-level handshake_func hooks to be passed in the
SSL_HANDSHAKE *. Later work will route it through the stack. False Start
is a little wonky, but I think this is cleaner overall.

bf48364a8c Support setting per-connection default session lifetime value
Due to recent changes, changing the SSL session timeout from cert_cb is
not possible anymore since the new |SSL_SESSION| is initialized *after*
cert_cb is run. The alternative would be using |SSL_CTX_set_timeout| but
the specific |SSL_CTX| could be shared by multiple |SSL|s.

Setting a value on a per-connection basis is useful in case timeouts
need to be calculated dynamically based on specific certificate/domain
information that would be retrieved from inside cert_cb (or other
callbacks).

It would also be possible to set the value to 0 to prevent session
resumption, which is not otherwise doable in the handshake callbacks.

123db57009 Measure session->timeout from ticket issuance.
The distinction for full handshakes is not meaningful (the timestamp is
currently the start of the handshake), but for renewed sessions, we
currently retain the timestamp of the original issuance.

Instead, when minting or receiving tickets, adjust session->time and
session->timeout so that session->time is the ticket issuance time.

This is still not our final TLS 1.3 behavior (which will need a both
renewable and non-renewable times to honor the server ticket lifetime),
but it gets us closer and unblocks handling ticket_age_add from TLS 1.3
draft 18 and sends the correct NewSessionTicket lifetime.

This fixes the ticket lifetime hint which we emit on the server to
mirror the true ticket lifetime. It also fixes the TLS 1.3 server code
to not set the ticket lifetime hint. There is no need to waste ticket
size with it, it is no longer a "hint" in TLS 1.3, and even in the TLS
1.3 code we didn't fill it in on the server.

a4c8ff0190 Move TLS 1.2 key exchange fields to SSL_HANDSHAKE.
SSL_HANDSHAKE is dropped after the handshake, so I've removed the logic
around smaller sizes. It's much simpler when we can use CBS_stow and
CBB_finish without extra bounds-checking.

Now not only the pointers but also the list itself is released after the
handshake completes.

a048678cd6 Move some fields from tmp to hs.
This releases memory associated with them after the handshake. Note this
changes the behavior of |SSL_get0_certificate_types| and
|SSL_get_client_CA_list| slightly. Both functions now return NULL
outside of the handshake. But they were already documented to return
something undefined when not called at the CertificateRequest.

A survey of callers finds none that would care. (Note
SSL_get_client_CA_list is used both as a getter for the corresponding
server config setter and to report client handshake properties. Only the
latter is affected.) It's also pretty difficult to imagine why a caller
would wish to query this stuff at any other time, and there are clear
benefits to dropping the CA list after the handshake (some servers send
ABSURDLY large lists).

This function is used by NGINX to enable specific curves for ECDH from a
configuration file. However when building with BoringSSL, since it's not
implmeneted, it falls back to using EC_KEY_new_by_curve_name() wich doesn't
support X25519.

65ac997f20 Implement draft-davidben-tls-grease-01.
This GREASEs cipher suites, groups, and extensions. For now, we'll
always place them in a hard-coded position. We can experiment with more
interesting strategies later.

If we add new ciphers and curves, presumably we prefer them over current
ones, so place GREASE values at the front. This prevents implementations
from parsing only the first value and ignoring the rest.

Add two new extensions, one empty and one non-empty. Place the empty one
in front (IBM WebSphere can't handle trailing empty extensions) and the
non-empty one at the end.

Upstream makes 0 mean "min/max supported version". Match that behavior,
although call it "default" instead. It shouldn't get you TLS 1.3 until
we're ready to turn it on everywhere.
