Right now I believe we are testing against DTLS 1.3 ClientHellos. Fix
this in preparation for making VersionTLS13 go elsewhere in the Go code.
Unfortunately, I made the mistake of mapping DTLS 1.0 to TLS 1.0 rather
than 1.1 in Go. This does mean the names of the tests naturally work out
correctly, but we have to deal with this awkward DTLS-1.1-shaped hole in
our logic.

TLS 1.3 defines a new SignatureScheme uint16 enum that is backwards
compatible on the wire with TLS1.2's SignatureAndHashAlgorithm. This
change updates the go testing code to use a single signatureAlgorithm
enum (instead of 2 separate signature and hash enums) in preparation for
TLS 1.3. It also unifies all the signing around this new scheme,
effectively backporting the change to TLS 1.2.
For now, it does not distinguish signature algorithms between 1.2 and
1.3 (RSA-PSS instead of RSA-PKCS1, ECDSA must match curve types). When
the C code is ready make a similar change, the Go code will be updated
to match.

This replaces the old key_exchange_info APIs and does not require the
caller be aware of the mess around SSL_SESSION management. They
currently have the same bugs around renegotiation as before, but later
work to fix up SSL_SESSION tracking will fix their internals.
For consistency with the existing functions, I've kept the public API at
'curve' rather than 'group' for now. I think it's probably better to
have only one name with a single explanation in the section header
rather than half and half. (I also wouldn't be surprised if the IETF
ends up renaming 'group' again to 'key exchange' at some point. We'll
see what happens.)

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.
