Conceptually in TLSv1.3 there can be multiple sessions associated with a
single connection. Each NewSessionTicket issued can be considered a
separate session. We can end up issuing multiple NewSessionTickets on a
single connection at the moment (e.g. in a post-handshake auth scenario).
Each of those issued tickets should have the new_session_cb called, it
should go into the session cache separately and it should have a unique
id associated with it (so that they can be found individually in the
cache).

With the current mechanism, old cipher strings that used to work in 1.1.0,
may inadvertently disable all TLSv1.3 ciphersuites causing connections to
fail. This is confusing for users.
In reality TLSv1.3 are quite different to older ciphers. They are much
simpler and there are only a small number of them so, arguably, they don't
need the same level of control that the older ciphers have.
This change splits the configuration of TLSv1.3 ciphers from older ones.
By default the TLSv1.3 ciphers are on, so you cannot inadvertently disable
them through your existing config.

When early data support was first added, this seemed like a good
idea, as it would allow applications to just add SSL_read_early_data()
calls as needed and have things "Just Work". However, for applications
that do not use TLS 1.3 early data, there is a negative side effect.
Having a nonzero max_early_data in a SSL_CTX (and thus, SSL objects
derived from it) means that when generating a session ticket,
tls_construct_stoc_early_data() will indicate to the client that
the server supports early data. This is true, in that the implementation
of TLS 1.3 (i.e., OpenSSL) does support early data, but does not
necessarily indicate that the server application supports early data,
when the default value is nonzero. In this case a well-intentioned
client would send early data along with its resumption attempt, which
would then be ignored by the server application, a waste of network
bandwidth.
Since, in order to successfully use TLS 1.3 early data, the application
must introduce calls to SSL_read_early_data(), it is not much additional
burden to require that the application also calls
SSL_{CTX_,}set_max_early_data() in order to enable the feature; doing
so closes this scenario where early data packets would be sent on
the wire but ignored.
Update SSL_read_early_data.pod accordingly, and make s_server and
our test programs into applications that are compliant with the new
requirements on applications that use early data.

* Add SSL_VERIFY_POST_HANDSHAKE to postpone client authentication until after

* Update SSL_VERIFY_CLIENT_ONCE now only sends out one CertRequest regardless
of when the certificate authentication takes place; either initial handshake,

* Remove some dead code

* Illegal use of PHA extension
* TLSv1.3 certificate tests
DTLS and TLS behave ever-so-slightly differently. So, when DTLS1.3 is
implemented, it's PHA support state machine may need to be different.
Add a TODO and a #error
Update handshake context to deal with PHA.
The handshake context for TLSv1.3 post-handshake auth is up through the
ClientFinish message, plus the CertificateRequest message. Subsequent
Certificate, CertificateVerify, and Finish messages are based on this
handshake context (not the Certificate message per se, but it's included
after the hash). KeyUpdate, NewSessionTicket, and prior Certificate
Request messages are not included in post-handshake authentication.
After the ClientFinished message is processed, save off the digest state
for future post-handshake authentication. When post-handshake auth occurs,
copy over the saved handshake context into the "main" handshake digest.
This effectively discards the any KeyUpdate or NewSessionTicket messages
and any prior post-handshake authentication.
This, of course, assumes that the ID-22 did not mean to include any
previous post-handshake authentication into the new handshake transcript.
This is implied by section 4.4.1 that lists messages only up to the
first ClientFinished.

Certain callback APIs allow the callback to request async processing
by trickling a particular error value up the stack to the application
as an error return from the handshake function. In those cases,
SSL_want() returns a code specific to the type of async processing
needed.
The create_ssl_connection() helper function for the tests is very
helpful for several things, including creating API tests. However,
it does not currently let us test the async processing functionality
of these callback interfaces, because the special SSL error codes
are treated as generic errors and the helper continues to loop until
it reaches its maximum iteration count.
Add a new parameter, 'want', that indicates an expected/desired
special SSL error code, so that the helper will terminate when
either side reports that error, giving control back to the calling
function and allowing the test to proceed.
