To prevent configuration/established session confusion, the handshake
session state is separated into the configured session (ssl->session)
and the newly created session (ssl->s3->new_session). Upon conclusion of
the handshake, the finalized session is stored
in (ssl->s3->established_session). During the handshake, any requests
for the session (SSL_get_session) return a non-resumable session, to
prevent resumption of a partially filled session. Sessions should only
be cached upon the completion of the full handshake, using the resulting
established_session. The semantics of accessors on the session are
maintained mid-renego.

For TLS 1.3, we will need to process more complex post-handshake

allow ssl3_get_message to be called at any point.
Note that this stops reserving SSL3_RT_MAX_PLAIN_LENGTH in init_buf

This isn't filled in on the client and Chromium no longer uses it for
plain RSA. It's redundant with existing APIs. This is part of removing
the need for callers to call SSL_get_session where possible.
SSL_get_session is ambiguous when it comes to renego. Some code wants
the current connection state which should not include the pending
handshake and some code wants the handshake scratch space which should.
Renego doesn't exist in TLS 1.3, but TLS 1.3 makes NewSessionTicket a
post-handshake message, so SSL_get_session is somewhat silly of an API
there too.
SSL_SESSION_get_key_exchange_info is a BoringSSL-only API, so we can
freely change it and replace it with APIs keyed on SSL. In doing so, I
think it is better to provide APIs like "SSL_get_dhe_group_size" and
"SSL_get_curve_id" rather than make the caller do the multi-step
SSL_get_current_cipher / SSL_CIPHER_is_ECDHE dance. To that end, RSA
key_exchange_info is pointless as it can already be determined from the
peer certificate.

OpenSSL's SSL_OP_NO_* flags allow discontinuous version ranges. This is a
nuisance for two reasons. First it makes it unnecessarily difficult to answer
"are any versions below TLS 1.3 enabled?". Second the protocol does not allow
discontinuous version ranges on the client anyway. OpenSSL instead picks the
first continous range of enabled versions on the client, but not the server.
This is bizarrely inconsistent. It also doesn't quite do this as the
ClientHello sending logic does this, but not the ServerHello processing logic.
So we actually break some invariants slightly. The logic is also cumbersome in
DTLS which kindly inverts the comparison logic.
First, switch min_version/max_version's storage to normalized versions. Next
replace all the ad-hoc version-related functions with a single
ssl_get_version_range function. Client and server now consistently pick a
contiguous range of versions. Note this is a slight behavior change for
servers. Version-range-sensitive logic is rewritten to use this new function.
