Adjust LPdir_unix.c on VMS for OpenSSL expectations

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

Reuse extension_is_relevant() in should_add_extension()

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 SSL/SSL_CTX_use_cert_and_key()

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.

Configure et al: rename all dso_* to module_* in shared-info.pl

Because there are already attributes with the dso_ prefix that are
used instead of the corresponding lib_ attributes rather than in
addition to them, it gets confusing to have similar or exactly the
same attributes working with different semantics on Unix.

So we rename those by changing the prefix dso_ to module_, and having
those work just like the shared_ attributes, but for DSOs.

Fix issues in ia32 RDRAND asm leading to reduced entropy

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.

Remove OPENSSL_USE_NODELETE guards in shlibloadtest

PR #3399 converted shlibloadtest to the new test framework. It also
seemed to add some `OPENSSL_USE_NODELETE` guards to the library
unloading part of the test. This part was added in a commit with this
description:

    Review feedback; use single main, #ifdef ADD_TEST

    Suppose OPENSSL_USE_NODELETE (via Nick Reilly)

Strangely though there doesn't seem to be any relevant review feedback
in that PR that could justify the addition of those guards. The guards
do not appear in 1.1.0.

Having the guards changes the nature of the test, so that we only test
library unloading on platforms where OPENSSL_USE_NODELETE is set (Linux
and Windows). I can't think of any good reason for this and as it doesn't
seem to be necessary in 1.1.0 so I think we should remove them.
