- In order to not add many X509_XXXX_with_libctx() functions the libctx and propq may be stored in the X509 object via a call to X509_new_with_libctx().
- Loading via PEM_read_bio_X509() or d2i_X509() should pass in a created cert using X509_new_with_libctx().
- Renamed some XXXX_ex() to XXX_with_libctx() for X509 API's.
- Removed the extra parameters in check_purpose..
- X509_digest() has been modified so that it expects a const EVP_MD object() and then internally it does the fetch when it needs to (via ASN1_item_digest_with_libctx()).
- Added API's that set the libctx when they load such as X509_STORE_new_with_libctx() so that the cert chains can be verified.

If we receive a KeyUpdate message (update requested) from the peer while
we are in the middle of a write, we should defer sending the responding
KeyUpdate message until after the current write is complete. We do this
by waiting to send the KeyUpdate until the next time we write and there is
no pending write data.
This does imply a subtle change in behaviour. Firstly the responding
KeyUpdate message won't be sent straight away as it is now. Secondly if
the peer sends multiple KeyUpdates without us doing any writing then we
will only send one response, as opposed to previously where we sent a
response for each KeyUpdate received.

This should be faster than going through an indirection and due to
fewer allocations, but I'm not seeing any significant performance
improvement; it seems to be within the margin of error in timing.

We were setting a limit of SSL3_RT_MAX_PLAIN_LENGTH on the size of the
ClientHello. AFAIK there is nothing in the standards that requires this
limit.
The limit goes all the way back to when support for extensions was first
added for TLSv1.0. It got converted into a WPACKET max size in 1.1.1. Most
likely it was originally added to avoid the complexity of having to grow
the init_buf in the middle of adding extensions. With WPACKET this is
irrelevant since it will grow automatically.
This issue came up when an attempt was made to send a very large
certificate_authorities extension in the ClientHello.
We should just remove the limit.

In TLSv1.2 and below a CertificateRequest is sent after the Certificate
from the server. This means that by the time the client_cert_cb is called
on receipt of the CertificateRequest a call to SSL_get_peer_certificate()
will return the server certificate as expected. In TLSv1.3 a
CertificateRequest is sent before a Certificate message so calling
SSL_get_peer_certificate() returns NULL.
To workaround this we delay calling the client_cert_cb until after we
have processed the CertificateVerify message, when we are doing TLSv1.3.

* 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.
