The old custom extensions API was not TLSv1.3 aware. Extensions are used
extensively in TLSv1.3 and they can appear in many different types of
messages. Therefore we need a new API to be able to cope with that.

hang waiting for a session file that's never going to arrive.

It turns out that /DSF didn't do any good for our purposes. Instead,
remove the CALL_DEBUG flag from any image we link. This ensures that
we can have debugging information in the image files, but don't
automatically end up in a debugging session upon image activation.
Unfortunately, this means the CALL_DEBUG must be turned on when there
is a need to run with the debugger activated, and to turn it off when
done. This has been documented in NOTES.VMS.

DBG$IMAGE_DSF_PATH, which is require so the debugger can find the Debug

There are cases when, if you pass a NULL UI_METHOD, the called

there may be cases when this is undesirable and one would rather send
in a UI that does absolutely nothing (sort of a /dev/null). UI_null()
is the UI_METHOD for this purpose.

Provide a callback interface that gives the application the ability
to adjust the nascent SSL object at the earliest stage of ClientHello
processing, immediately after extensions have been collected but
before they have been processed.
This is akin to BoringSSL's "select_certificate_cb" (though it is not
API compatible), and as the name indicates, one major use is to examine
the supplied server name indication and select what certificate to
present to the client. However, it can also be used to make more
sweeping configuration changes to the SSL object according to the
selected server identity and configuration. That may include adjusting
the permitted TLS versions, swapping out the SSL_CTX object (as is
traditionally done in a tlsext_servername_callback), changing the
server's cipher list, and more.
We also wish to allow an early callback to indicate that it needs to perform
additional work asynchronously and resume processing later. To that effect,
refactor the second half of tls_process_client_hello() into a subroutine to be
called at the post-processing stage (including the early callback itself), to
allow the callback to result in remaining in the same work stage for a later
call to succeed. This requires allocating for and storing the CLIENTHELLO_MSG
in the SSL object to be preserved across such calls, but the storage is
reclaimed after ClientHello processing finishes.
Information about the CliehtHello is available to the callback by means of
accessor functions that can only be used from the early callback. This allows
extensions to make use of the existing internal parsing machinery without
exposing structure internals (e.g., of PACKET), so that applications do not
have to write fragile parsing code.
Applications are encouraged to utilize an early callback and not use
a servername_callback, in order to avoid unexpected behavior that
occurs due to the relative order of processing between things like
session resumption and the historical servername callback.
Also tidy up nearby style by removing unnecessary braces around one-line
conditional bodies.

Move ssl_bytes_to_cipher_list() to ssl_lib.c and create a public
wrapper around it. This lets application early callbacks easily get
SSL_CIPHER objects from the raw ciphers bytes without having to
reimplement the parsing code. In particular, they do not need to
know the details of the sslv2 format ClientHello's ciphersuite
specifications.
Document the new public function, including the arguably buggy behavior
of modifying the supplied SSL object. On the face of it, such a function
should be able to be pure, just a direct translation of wire octets to
internal data structures.

implementation expands the evptests by including the test cases from
RFC 5794 and ARIA official site rather than providing an individual

applications, but not TLS. Implemented modes are CBC, CFB1, CFB8,

TLSProxy normally fires off s_client, which creates a connection to the
server. TLSProxy also pipes some data to send to the process and s_client
automatically exits when the pipe hits eof. Unfortunately this means that
it sends the data and closes before it has processed the NewSessionTicket
returned from the server in TLSv1.3. This commits adds an option for
s_client to stay loaded until the sesion has been processed. A side effect
of this is that s_client never sends a close_notify in this mode, so we
count success as seeing that data has been transferred.
