- When used as KEMs in TLS the ECDHE algorithms are NOT subjected to
HPKE Extract/Expand key derivation. Instead the TLS HKDF is used
as usual.
- Consequently these KEMs are just the usual ECDHE key exchange
operations, be it with the encap ECDH private key unavoidably
ephemeral.
- A new "MLX" KEM provider is added that supports four hybrids of EC/ECX
DH with ML-KEM:
* ML-KEM-768 + X25519
* ML-KEM-1024 + X448
* P-256 + ML-KEM-768
* P-384 + ML-KEM-1024
- Support listing of implemented TLS groups.
The SSL_CTX_get0_implemented_groups() function and new
`openssl list -tls-groups` and `openssl list -all-tls-groups`
commands make it possible to determine which groups are
implemented by the SSL library for a particular TLS version
or range of versions matching an SSL_CTX.

This PR is the implementation of concluded discussion that occurred in a
draft PR #25605. This changes were mainly authored by @martinschmatz
with some contribution from myself.
It addresses issue #21633
This extends the group list definition to support a more complex
definition while still retaining backward compatibility with the simple
form of colon separated groups.
Details of the agreed format and expected behaviour can be found in
#25605 and in the documentation changes.

TLS device offload allows to perform zerocopy sendfile transmissions.
FreeBSD provides this feature by default, and Linux 5.19 introduced it
as an opt-in. Zerocopy improves the TX rate significantly, but has a
side effect: if the underlying file is changed while being transmitted,
and a TCP retransmission happens, the receiver may get a TLS record
containing both new and old data, which leads to an authentication
failure and termination of connection. This effect is the reason Linux
makes a copy on sendfile by default.
This commit adds support for TLS zerocopy sendfile on Linux disabled by
default to avoid any unlikely backward compatibility issues on Linux,
although sacrificing consistency in OpenSSL's behavior on Linux and
FreeBSD. A new option called KTLSTxZerocopySendfile is added to enable
the new zerocopy behavior on Linux. This option should be used when the
the application guarantees that the file is not modified during
transmission, or it doesn't care about breaking the connection.
The related documentation is also added in this commit. The unit test
added doesn't test the actual functionality (it would require specific
hardware and a non-local peer), but solely checks that it's possible to
set the new option flag.

Add -client_renegotiation flag support. The -client_renegotiation flag is
equivalent to SSL_OP_ALLOW_CLIENT_RENEGOTIATION. Add support to the app,
the config code, and the documentation.
Add SSL_OP_ALLOW_CLIENT_RENEGOTIATION to the SSL tests. We don't need to
always enable it, but there are so many tests so this is the easiest thing
to do.
Add a test where client tries to renegotiate and it fails as expected. Add
a test where server tries to renegotiate and it succeeds. The second test
is supported by a new flag, -immediate_renegotiation, which is ignored on
the client.

Previously we would set SSL_OP_LEGACY_SERVER_CONNECT by default in
SSL_CTX_new(), to allow connections to legacy servers that did not
implement RFC 5746.
It has been more than a decade since RFC 5746 was published, so
there has been plenty of time for implmentation support to roll out.
Change the default behavior to be to require peers to support
secure renegotiation. Existing applications that already cleared
SSL_OP_LEGACY_SERVER_CONNECT will see no behavior change, as
re-clearing the flag is just a little bit of redundant work.
The old behavior is still available by explicitly setting the flag
in the application.
Also remove SSL_OP_LEGACY_SERVER_CONNECT from SSL_OP_ALL, for
similar reasons.
Document the behavior change in CHANGES.md, and update the
SSL_CTX_set_options() and SSL_CONF_cmd manuals to reflect the change
in default behavior.

The 'MinProtocol' and 'MaxProtocol' configuration commands now silently
ignore TLS protocol version bounds when configurign DTLS-based contexts,
and conversely, silently ignore DTLS protocol version bounds when
configuring TLS-based contexts. The commands can be repeated to set
bounds of both types. The same applies with the corresponding
"min_protocol" and "max_protocol" command-line switches, in case some
application uses both TLS and DTLS.
SSL_CTX instances that are created for a fixed protocol version (e.g.
TLSv1_server_method()) also silently ignore version bounds. Previously
attempts to apply bounds to these protocol versions would result in an
error. Now only the "version-flexible" SSL_CTX instances are subject to
limits in configuration files in command-line options.

While stereotyped repetitions are frowned upon in literature, they
serve a useful purpose in manual pages, because it is easier for
the user to find certain information if it is always presented in
the same way. For that reason, this commit harmonizes the varying
formulations in the HISTORY section about which functions, flags,
etc. were added in which OpenSSL version.
It also attempts to make the pod files more grep friendly by
avoiding to insert line breaks between the symbol names and the
corresponding version number in which they were introduced
(wherever possible). Some punctuation and typographical errors
were fixed on the way.

In 1.0.2 you could configure automatic ecdh params by using the
ECDHParameters config directive and setting it to the value
"+Automatic" or just "Automatic". This is no longer required in 1.1.0+
but we still recognise the "+Automatic" keyword for backwards compatibility.
However we did not recognise just "Automatic" without the leading "+" which
is equally valid. This commit fixes that omission.
