There is a requirements of having access to a live entropy source
which we can't do with the default callbacks. If you need prediction
resistance you need to set up your own callbacks that follow the
requirements of NIST SP 800-90C.

This commit moves the internal header file "internal/rand.h" to
<openssl/rand_drbg.h>, making the RAND_DRBG API public.
The RAND_POOL API remains private, its function prototypes were
moved to "internal/rand_int.h" and converted to lowercase.
Documentation for the new API is work in progress on GitHub #5461.

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 OPENSSL_DIR_read implemented by LPdir_unix.c gets a Unixy path,
it will return file names like you'd expect them on Unix.
However, if given a path with VMS syntax, such as "[.foo]", it returns
file names with generation numbers, such as "bar.txt;1", which makes
sense for VMS expectations, but can be surprising for OpenSSL.
Our solution is to simply shave off the generation number if
OPENSSL_DIR_read() expects there should be one, and make sure not to
return the same file name twice. Note that VMS filesystems are case
insensitive, so the check for duplicate file names are done without
regard to character case.

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.

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.

With the support of "make variables" comes the possibility for the
user to override them. However, we need to make a difference between
defaults that we use (and that should be overridable by the user) and
flags that are crucial for building OpenSSL (should not be
overridable).
Typically, overridable flags are those setting optimization levels,
warnings levels, that kind of thing, while non-overridable flags are,
for example, macros that indicate aspects of how the config target
should be treated, such as L_ENDIAN and B_ENDIAN.
We do that differentiation by allowing upper case attributes in the
config targets, named exactly like the "make variables" we support,
and reserving the lower case attributes for non-overridable project
flags.

This patch fixes two issues in the ia32 RDRAND assembly code that result in a
(possibly significant) loss of entropy.
The first, less significant, issue is that, by returning success as 0 from
OPENSSL_ia32_rdrand() and OPENSSL_ia32_rdseed(), a subtle bias was introduced.
Specifically, because the assembly routine copied the remaining number of
retries over the result when RDRAND/RDSEED returned 'successful but zero', a
bias towards values 1-8 (primarily 8) was introduced.
The second, more worrying issue was that, due to a mixup in registers, when a
buffer that was not size 0 or 1 mod 8 was passed to OPENSSL_ia32_rdrand_bytes
or OPENSSL_ia32_rdseed_bytes, the last (n mod 8) bytes were all the same value.
This issue impacts only the 64-bit variant of the assembly.
This change fixes both issues by first eliminating the only use of
OPENSSL_ia32_rdrand, replacing it with OPENSSL_ia32_rdrand_bytes, and fixes the
register mixup in OPENSSL_ia32_rdrand_bytes. It also adds a sanity test for
OPENSSL_ia32_rdrand_bytes and OPENSSL_ia32_rdseed_bytes to help catch problems
of this nature in the future.
