Maxim Mikityanskiy cd715b7e7f 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.

John Baldwin f16e52b67c Correct the return value of BIO_get_ktls_*().
BIO_get_ktls_send() and BIO_get_ktls_recv() are documented as
returning either 0 or 1.  However, they were actually returning the
internal value of the associated BIO flag for the true case instead of
1.

Also trim redundant ternary operators.

John Baldwin 7f0f88240e Slightly abstract ktls_start() to reduce OS-specific #ifdefs.
Instead of passing the length in from the caller, compute the length
to pass to setsockopt() inside of ktls_start().  This isolates the
OS-specific behavior to ktls.h and removes it from the socket BIO
implementations.

John Baldwin 4b09e19216 Fix the socket BIO control methods to use ktls_crypto_info_t.
This is mostly a cosmetic cleanup I missed when adding the
ktls_crypto_info_t type.  However, while fixing this I noticed that
the changes to extract the size from crypto_info from the wrapper
structure for Linux KTLS had not been propagated from bss_sock.c to
bss_conn.c, so I've fixed that to use the correct length.

If we hit an EOF while reading in libssl then we will report an error
back to the application (SSL_ERROR_SYSCALL) but errno will be 0. We add
an error to the stack (which means we instead return SSL_ERROR_SSL) and
therefore give a hint as to what went wrong.
