This requires changing semantics of the keymgmt_has()
function a little in the sense that it now returns 1
if the selection has no meaning for the key type. It
was already doing so for ECX keys for example.
The keymgmt_validate function semantics is changed
similarly to allow passing validation on the same
selection that the key returns 1 for.

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.

The low level DH API has two functions for checking parameters:
DH_check_ex() and DH_check_params_ex(). The former does a "full" check,
while the latter does a "quick" check. Most importantly it skips the
check for a safe prime. We're ok without using safe primes here because
we're doing ephemeral DH.
Now that libssl is fully using the EVP API, we need a way to specify that
we want a quick check instead of a full check. Therefore we introduce
EVP_PKEY_param_check_quick() and use it.
