10, 15 and 18 seem quite unnatural byte counts in the context of hex
dumps. Standardize on 24 bytes for signatures (to stay within the 80
characters limit) and 16 bytes for everything else.
Adjust all test cert dumps to match the new output format.

For SHAKE algorithms we now return 0 from EVP_MD_size().
So all the places that check for < 0 needed to change to <= 0
(Otherwise the behaviour will be to digest nothing in most cases).

ISO 19790:2012/Cor.1:2015 7.9 requires cryptographic module to provide
methods to zeroise all unproctected security sensitive parameters
(which inclues both Critical/Private **and** Public security
parameters). And those that are temprorarly stored are required to be
zeroised after they are no longer needed at security levels 2 and
higher.
Comply with the above requirements by always zeroising public security
parameters whenever they are freed.
This is currently done under the FIPS feature, however the requirement
comes from the ISO 19790:2012 which may also be needed in other
jurisdictions. If not always. Note FIPS 140-3 includes ISO 19790:2012
by reference.

Discovered during coverage testing.
Remove unneccesary check when using ossl_dh_get0_params() and
ossl_dsa_get0_params(). These point to addresses and can not fail
for any existing calls.
Make dsa keygen tests only available in the FIPS module - as they are
not used in the default provider.
Change ossl_ffc_set_digest() to return void as it cannot fail.

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.

Including e_os.h with a path from a header file doesn't work well on
certain exotic platform. It simply fails to build.
Since we don't seem to be able to stop ourselves, the better move is
to move e_os.h to an include directory that's part of the inclusion
path given to the compiler.

An extra field got added to the ffc flags related to FIPS-186-2 key validation, but this field was

Fixes#14480
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.
