These functions are similar to SSL_CTX_set_cookie_{generate,verify}_cb,
but used for the application-controlled portion of TLS1.3 stateless
handshake cookies rather than entire DTLSv1 cookies.

There are things depending on configdata.pm.  However, it's perfectly
possible that there is one in the source directory from a previous
build, and that might disrupt an out of source build.  To avoid this
conflict, make sure never to use the source tree configdata.pm in that
case, i.e. make the hard assumption that it's a generated file in the
build tree, which it is.

The introduction of thread local public and private DRBG instances (#5547)
makes it very cumbersome to change the reseeding (time) intervals for
those instances. This commit provides a function to set the default
values for all subsequently created DRBG instances.

 int RAND_DRBG_set_reseed_defaults(
                                   unsigned int master_reseed_interval,
                                   unsigned int slave_reseed_interval,
                                   time_t master_reseed_time_interval,
                                   time_t slave_reseed_time_interval
                                   );

The function is intended only to be used during application initialization,
before any threads are created and before any random bytes are generated.

At the core of things is the concept that each extension is only
defined in certain context(s) -- the ClientHello, EncryptedExtensions,
etc., and sometimes only for a specific protocol or protocol range;
we want to enforce that we only parse or generate extensions in the
context(s) for which they are defined.  There is some subtlety here,
in that the protocol version in use is not known when generating the
ClientHello (but it is known when the ClientHello extensions are
being parsed!), so the SSL_IS_TLS13() macro must be used with caution.
Nonetheless, by making assertions about whether we are acting in a
server role and whether the current context is (not) a ClientHello,
we can consolidate almost all of the logic for determining whether
an extension is permitted in a given protocol message, whether we
are generating or parsing that message.

The only logic that remains separate relates to generating the ClientHello,
as it depends on an external factor (the maximum permitted TLS version) that
is not defined in the parsing context.

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.

Instead of looking at 3rd, let's look at last. This allows to override
flavour from template in a simple way.

Configurations/10-main.conf: define generic "flavour" in VC-common
template. Since VC-W32 was the only recognized "flavour", remove
"flavour" definitions from all targets/templates, but VC-WIN32. And
rename VC-W32 to VC-WOW.

We're currently using the attributes 'defines', 'cppflags', 'cflags'
etc quite liberally, with no regard for where that ends up.  Quite a
few of those flags are actually only relevant for the libraries
(mostly libcrypto), so it's safe to say that those could be applied to
the libraries only.

So, we move some of those flags to 'lib_defines', 'lib_cppflags',
'lib_cflags', etc.
