Coverage testing showed that ossl_ffc_params_fromdata() was not setting
OSSL_PKEY_PARAM_FFC_DIGEST_PROPS.
Adding a negative test also showed that ossl_ffc_params_copy() did not
do a shallow copy of the digest or digest property.

Fixes CVE-2023-0217
When attempting to do a BN_Copy of params->p there was no NULL check.
Since BN_copy does not check for NULL this is a NULL reference.
As an aside BN_cmp() does do a NULL check, so there are other checks
that fail because a NULL is passed. A more general check for NULL params
has been added for both FFC public and private key validation instead.

Longer private key sizes unnecessarily raise the cycles needed to
compute the shared secret without any increase of the real security.
We use minimum key sizes as defined in RFC7919.
For arbitrary parameters we cannot know whether they are safe
primes (we could test but that would be too inefficient) we have
to keep generating large keys.
However we now set a small dh->length when we are generating safe prime
parameters because we know it is safe to use small keys with them.
That means users need to regenerate the parameters if they
want to take the performance advantage of small private key.

Since we don't seem to be able to stop ourselves, the better move is

An internal flag that is set during param gen was not being tested, so
the wrong type was used to select the dsa domain param validation method.
In the default provider - if no gen_type is set then by default the fips186_4 gentype
will be selected when pbits >=2048 otherwise it selects fips186_2.
The fips provider ignores the gen_type and always uses fips186_4.
Before this change dsa used fips186_2 by default in the default
provider.

EVP_PKEY_CTX_set_dh_ functions were only available when DH was enabled
('no-dsa' not configured). However, that makes it impossible to use
these functions with an engine or a provider that happens to implement
DH. This change solves that problem by shuffling these functions to
more appropriate places.
By consequence, there are a number of places where we can remove the
check of OPENSSL_NO_DH. This requires some re-arrangements of
internal tables to translate between numeric identities and names.

- The dsa keygen assumed valid p, q, g values were being passed. If this is not correct then it is
possible that dsa keygen can either hang or segfault.
The fix was to do a partial validation of p, q, and g inside the keygen.
- Fixed a potential double free in the dsa keypair test in the case when in failed (It should never fail!).
It freed internal object members without setting them to NULL.
- Changed the FFC key validation to accept 1024 bit keys in non fips mode.
- Added tests that use both the default provider & fips provider to test these cases.

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.
