By the time the keygen is called the references to strings inside the
gen ctx are floating pointers. A strdup solves this problem.

There is no option to output DH params in DER form. -outform doesn't
apply to -genparam with 'openssl genpkey', and it shouldn't.

DH_set0_pqg() is now responsible for caching the nid, q and length.
DH with or without named safe prime groups now default to using the maximum private key length (BN_num_bits(q) - 1)
when generating a DH private key. The code is now shared between fips and non fips mode for DH key generation.
The OSSL_PKEY_PARAM_DH_PRIV_LEN parameter can be used during keygen to override the maximum private key length to be
in the range (2 * strength ... bits(q) - 1). Where the strength depends on the length of p.
Added q = (p - 1) / 2 safe prime BIGNUMS so that the code is data driven (To simplify adding new names).
The BIGNUMS were code generated.
