The scrypt and RSA-PSS documents were a mixture of section 3 and
section 7 material. With pre-1.1.1 OpenSSL, this is understandable,
since we had a different directory layout. With 1.1.1, we've moved to
the typical man-page directory layout, and the documents need to be
updated accordingly.
Also, the scrypt document contained a description of
EVP_PKEY_CTX_set1_pbe_pass(), which is a generic function rather than
an scrypt specific function, and therefore should be documented
separately.

Add functions that will do the work of assigning certificate, privatekey
and chain certs to an SSL or SSL_CTX. If no privatekey is given, use the
publickey. This will permit the keys to pass validation for both ECDSA
and RSA. If a private key has already been set for the certificate, it
is discarded. A real private key can be set later.
This is an all-or-nothing setting of these parameters. Unlike the
SSL/SSL_CTX_use_certificate() and SSL/SSL_CTX_use_PrivateKey() functions,
the existing cert or privatekey is not modified (i.e. parameters copied).
This permits the existing cert/privatekey to be replaced.
It replaces the sequence of:
* SSL_use_certificate()
* SSL_use_privatekey()
* SSL_set1_chain()
And may actually be faster, as multiple checks are consolidated.
The private key can be NULL, if so an ENGINE module needs to contain the
actual private key that is to be used.
Note that ECDH (using the certificate's ECDSA key) ciphers do not work
without the private key being present, based on how the private key is
used in ECDH. ECDH does not offer PFS; ECDHE ciphers should be used instead.

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.

DTLS and TLS behave ever-so-slightly differently. So, when DTLS1.3 is

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.

Reseeding is handled very differently by the classic RAND_METHOD API
and the new RAND_DRBG api. These differences led to some problems when
the new RAND_DRBG was made the default OpenSSL RNG. In particular,
RAND_add() did not work as expected anymore. These issues are discussed
on the thread '[openssl-dev] Plea for a new public OpenSSL RNG API'
and in Pull Request #4328. This commit fixes the mentioned issues,
introducing the following changes:
- Replace the fixed size RAND_BYTES_BUFFER by a new RAND_POOL API which
facilitates collecting entropy by the get_entropy() callback.
- Don't use RAND_poll()/RAND_add() for collecting entropy from the
get_entropy() callback anymore. Instead, replace RAND_poll() by
RAND_POOL_acquire_entropy().
- Add a new function rand_drbg_restart() which tries to get the DRBG
in an instantiated state by all means, regardless of the current
state (uninstantiated, error, ...) the DRBG is in. If the caller
provides entropy or additional input, it will be used for reseeding.
- Restore the original documented behaviour of RAND_add() and RAND_poll()
(namely to reseed the DRBG immediately) by a new implementation based
on rand_drbg_restart().
- Add automatic error recovery from temporary failures of the entropy
source to RAND_DRBG_generate() using the rand_drbg_restart() function.

The pub_key field for DH isn't actually used in DH_compute_key at all.
(Note the peer public key is passed in as as BIGNUM.) It's mostly there
so the caller may extract it from DH_generate_key. It doesn't
particularly need to be present if filling in a DH from external
parameters.
The check in DH_set0_key conflicts with adding OpenSSL 1.1.0 to Node.
Their public API is a thin wrapper over the old OpenSSL one:
https://nodejs.org/api/crypto.html#crypto_class_diffiehellman
They have separate setPrivateKey and setPublicKey methods, so the public
key may be set last or not at all. In 1.0.2, either worked fine since
operations on DH objects generally didn't use the public key. (Like
with OpenSSL, Node's setPublicKey method is also largely a no-op, but so
it goes.) In 1.1.0, DH_set0_key prevents create a private-key-only DH
object.

With the introduction of RAND_poll_ex(), the `RAND_add()` calls were
replaced by meaningless cb(...). This commit changes the 'cb(...)'
calls back to 'rand_add(...)' calls by changing the signature as follows:
-int RAND_poll_ex(RAND_poll_fn cb, void *arg);
+int RAND_poll_ex(RAND_poll_cb rand_add, void *arg);
Changed the function typedef name to 'RAND_poll_cb' to emphasize the fact
that the function type represents a callback function.

The existing function SSL_get_current_cipher() queries the
current session for the ciphersuite in use, but there is no way
for application code to determine what ciphersuite has been
negotiated and will be used in the future, prior to ChangeCipherState
(or the TLS 1.3 equivalent) causing the new cipher to take effect and
become visible in the session information. Expose this information
to appropriate application callbacks to use during the handshake.
The name SSL_get_pending_cipher() was chosen for compatibility with
BoringSSL's routine of that name.
Improve the note on macro implementations in SSL_get_current_cipher.pod
while here.

OpenSSL already has the feature of SSL_MODE_RELEASE_BUFFERS that can
be set to release the read or write buffers when data has finished
reading or writing. OpenSSL will automatically re-allocate the buffers
as needed. This can be quite aggressive in terms of memory allocation.
This provides a manual mechanism. SSL_free_buffers() will free
the data buffers if there's no pending data. SSL_alloc_buffers()
will realloc them; but this function is not strictly necessary, as it's
still done automatically in the state machine.
