Add support for KTLS zerocopy sendfile on Linux

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

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.

Enforce secure renegotiation support by default

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.

Avoid errors with a priori inapplicable protocol bounds

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.
