This function needs to be power up tested as part of the FIPS validation and
thus it needs to be inside the provider boundary. This is realised by
introducing a new KDF "TLS13-KDF" which does the required massaging of
parameters but is otherwise functionally equivalent to HKDF.

The initial implementation always deferred the generation of the
requested ticket(s) until the next application write, but this
is not a great fit for what it actually does, architecturally wise.
A request to send a session ticket means entering back into the
handshake state machine (or "in init", as it's known in the
implementation). The state machine transition is not something that
only occurs at an application-data write, and in general could occur at
any time. The only constraint is that we can't enter "init" while in
the middle of writing application data. In such cases we will need to
wait until the next TLS record boundary to enter the state machine,
as is currently done.
However, there is no reason why we cannot enter the handshake state
machine immediately in SSL_new_session_ticket() if there are no
application writes pending. Doing so provides a cleaner API surface to
the application, as then calling SSL_do_handshake() suffices to drive
the actual ticket generation. In the previous state of affairs a dummy
zero-length SSL_write() would be needed to trigger the ticket
generation, which is a logical mismatch in the type of operation being
performed.
This commit should only change whether SSL_do_handshake() vs zero-length
SSL_write() is needed to immediately generate a ticket after the
SSL_new_session_ticket() call -- the default behavior is still to defer
the actual write until there is other application data to write, unless
the application requests otherwise.

It can be useful to know what group was used for the handshake's
key exchange process even on non-TLS 1.3 connections. Allow this
API, new in OpenSSL 3.0.0, to be used on other TLS versions as well.
Since pre-TLS-1.3 key exchange occurs only on full handshakes, this
necessitates adding a field to the SSL_SESSION object to carry the
group information across resumptions. The key exchange group in the
SSL_SESSION can also be relevant in TLS 1.3 when the resumption handshake
uses the "psk_ke" key-exchange mode, so also track whether a fresh key
exchange was done for TLS 1.3.
Since the new field is optional in the ASN.1 sense, there is no need
to increment SSL_SESSION_ASN1_VERSION (which incurs strong incompatibility
churn).

TLS 1.3 allows for the "psk_ke" and "psk_dhe_ke" key-exchange modes.
Only the latter mode introduces a new ephemeral (Diffie-Hellman)
key exchange, with the PSK being the only key material used in the
former case.
It's a compliance requirement of RFC 8446 that the server MUST NOT
send a KeyShareEntry when using the "psk_ke" mode, but prior to
this commit we would send a key-share based solely on whether the
client sent one. This bug goes unnoticed in our internal test suite
since openssl communicating with openssl can never negotiate the
PSK-only key-exchange mode. However, we should still be compliant
with the spec, so check whether the DHE mode was offered and don't
send a key-share if it wasn't.

libimplementations.a was a nice idea, but had a few flaws:
1. The idea to have common code in libimplementations.a and FIPS
sensitive helper functions in libfips.a / libnonfips.a didn't
catch on, and we saw full implementation ending up in them instead
and not appearing in libimplementations.a at all.
2. Because more or less ALL algorithm implementations were included
in libimplementations.a (the idea being that the appropriate
objects from it would be selected automatically by the linker when
building the shared libraries), it's very hard to find only the
implementation source that should go into the FIPS module, with
the result that the FIPS checksum mechanism include source files
that it shouldn't
To mitigate, we drop libimplementations.a, but retain the idea of
collecting implementations in static libraries. With that, we not
have:
libfips.a
Includes all implementations that should become part of the FIPS
provider.
liblegacy.a
Includes all implementations that should become part of the legacy
provider.
libdefault.a
Includes all implementations that should become part of the
default and base providers.
With this, libnonfips.a becomes irrelevant and is dropped.
libcommon.a is retained to include common provider code that can be
used uniformly by all providers.
