Make the naming scheme for dispatched functions more consistent

The new naming scheme consistently usese the `OSSL_FUNC_` prefix for all
functions which are dispatched between the core and providers.

This change includes in particular all up- and downcalls, i.e., the
dispatched functions passed from core to provider and vice versa.

- OSSL_core_  -> OSSL_FUNC_core_
- OSSL_provider_ -> OSSL_FUNC_core_

For operations and their function dispatch tables, the following convention
is used:

  Type                 | Name (evp_generic_fetch(3))       |
  ---------------------|-----------------------------------|
  operation            | OSSL_OP_FOO                       |

Add an SSL_dup test

(Merged from https://github.com/openssl/openssl/pull/12180)

Don't attempt to duplicate the BIO state in SSL_dup

SSL_dup attempted to duplicate the BIO state if the source SSL had BIOs
configured for it. This did not work.

Firstly the SSL_dup code was passing a BIO ** as the destination
argument for BIO_dup_state. However BIO_dup_state expects a BIO * for that
parameter. Any attempt to use this will either (1) fail silently, (2) crash
or fail in some other strange way.

Secondly many BIOs do not implement the BIO_CTRL_DUP ctrl required to make
this work.

Thirdly, if rbio == wbio in the original SSL object, then an attempt is made
to up-ref the BIO in the new SSL object - even though it hasn't been set
yet and is NULL. This results in a crash.

This appears to have been broken for a very long time with at least some of
the problems described above coming from SSLeay. The simplest approach is
to just remove this capability from the function.

Really this test should go in evp_extra_test. However that doesn't
currently support a non-default libctx (with the "null" provider in the
default libctx). So (for now) we create evp_extra_test2.c

Ensure creating an EC public key uses the libctx

Creating an EC public key from the private key uses random numbers
internally, which require use of the proper libtx. Therefore we make
sure the libctx is used during this operation.

Make EVP_PKEY_CTX_[get|set]_group_name work for ECX too

The previous commits made EVP_PKEY_CTX_[get|set]_group_name work for
EC and DH keys. We now extend this to ECX. Even though that keys with
these key types only have one group we still allow it to be explicitly
set so that we have only one codepath for all keys. Setting the group
name for these types of keys is optional, but if you do so it must have

aren't actually needed for this key type, but for the same reasons as
above (to ensure a single codepath for users of these algorithms) we
enable it anyway.

Add ACVP fips module tests

For FIPS validation purposes - Automated Cryptographic Validation Protocol (ACVP) tests need to be
performed. (See https://github.com/usnistgov/ACVP). These tests are very similiar to the old CAVS tests.

This PR uses a hardwired subset of these test vectors to perform similiar operations,
to show the usage and prove that the API's are able to perform the required operations.
It may also help with communication with the lab (i.e- The lab could add a test here to show
a unworking use case - which we can then address).

The EVP layer performs these tests instead of calling lower level API's
as was done in the old FOM.
Some of these tests require access to internals that are not normally allowed/required.

The config option 'acvp_tests' (enabled by default) has been added so that this
access may be removed.

The mechanism has been implemented as additional OSSL_PARAM values that can be set and get.
A callback mechanism did not seem to add any additional benefit.
These params will not be added to the gettables lists.

Refactor BN_R_NO_INVERSE logic in internal functions

Closes #12129

As described in https://github.com/openssl/openssl/issues/12129 the
readability of the internal functions providing the two alternative
implementations for `BN_mod_inverse()` is a bit lacking.

Both these functions are now completely internal, so we have the
flexibility needed to slightly improve readability and remove
unnecessary NULL checks.

The main changes here are:
- rename `BN_mod_inverse_no_branch()` as `bn_mod_inverse_no_branch()`:
  this function is `static` so it is not even visible within the rest of
  libcrypto. By convention upcase prefixes are reserved for public
  functions.
- remove `if (pnoinv == NULL)` checks in `int_bn_mod_inverse()`: this
  function is internal to the BN module and we can guarantee that all
  callers pass non-NULL arguments.
- `bn_mod_inverse_no_branch()` takes an extra `int *pnoinv` argument, so
  that it can signal if no inverse exists for the given inputs: in this
  way the caller is in charge of raising `BN_R_NO_INVERSE` as it is the
  case for the non-consttime implementation of `int_bn_mod_inverse()`.
- `BN_mod_inverse()` is a public function and must guarantee that the
  internal functions providing the actual implementation receive valid
  arguments. If the caller passes a NULL `BN_CTX` we create a temporary
  one for internal use.
- reorder function definitions in `crypto/bn/bn_gcd.c` to avoid forward
  declaration of `static` functions (in preparation for inlining).
- inline `bn_mod_inverse_no_branch()`.
