DHE ciphers are gone, so we no longer need to clear drop the "group_id"
field there. That leaves static RSA, but:
- We mass-invalidated every serialized client session in
364f7a6d21, long after we stopped
filling in key_exchange_info on the client.
- Server sessions were not mass-invalidated, but static RSA
key_exchange_info never worked on the server.
This means it is safe to remove this logic.

As a precursor to removing the code entirely later, disable the protocol
by default. Callers must use SSL_CTX_set_min_version to enable it.
This change also makes SSLv3_method *not* enable SSL 3.0. Normally
version-specific methods set the minimum and maximum version to their
version. SSLv3_method leaves the minimum at the default, so we will
treat it as all versions disabled. To help debugging, the error code is
switched from WRONG_SSL_VERSION to a new NO_SUPPORTED_VERSIONS_ENABLED.
This also defines OPENSSL_NO_SSL3 and OPENSSL_NO_SSL3_METHOD to kick in
any no-ssl3 build paths in consumers which should provide a convenient
hook for any upstreaming changes that may be needed. (OPENSSL_NO_SSL3
existed in older versions of OpenSSL, so in principle one may encounter
an OpenSSL with the same settings.)

This only works at TLS 1.2 and above as, before TLS 1.2, there is no way
to advertise support for Ed25519 or negotiate the correct signature
algorithm. Add tests for this accordingly.
For now, this is disabled by default on the verifying side but may be
enabled per SSL_CTX. Notably, projects like Chromium which use an
external verifier may need changes elsewhere before they can enable it.
(On the signing side, we can assume that if the caller gave us an
Ed25519 certificate, they mean for us to use it.)

When we refactored all the buffering logic, we retained upstream
OpenSSL's allocation patterns. In particular, we always allocated fixed
size write buffer, even though, unlike when reading, we trivially know a
tighter bound (namely however much we happen to be writing right now).
Since the cutoff for when Windows' malloc starts having a hard time is
just below the TLS maximum record size, do the more natural thing of
allocating what we need to hold outgoing ciphertext.
(This only does anything to the write half. Read half is a bit more
involved.)

Once 0-RTT data is added to the current 0-RTT logic, the server will
trigger a write when processing incoming data via SSL_read. This means
SSL_read will block on transport write, which is something we've not
tried to avoid far (assuming no renegotiation).
The specification allows for tickets to be sent at half-RTT by
predicting the client Finished. By doing this we both get the tickets on
the wire sooner and avoid confusing I/O patterns. Moreover, we
anticipate we will need this mode for one of the QUIC stateless reject
patterns.
This is tested by always processing NewSessionTickets in the
ExpectHalfRTTData path on 0-RTT connections. As not other
implementations using BoGo may not do this, this is configurable via the
shim config.
