The types OSSL_DISPATCH, OSSL_ITEM, OSSL_ALGORITHM, OSSL_PARAM,
OSSL_CALLBACK, and OSSL_PASSPHRASE_CALLBACK are described in their own
manual page, so we change every mention of them to links to those pages.

Functions like EVP_PKEY_sign_init() do an implicit fetch of the
operation implementation (EVP_SIGNATURE in this case), then get the
KEYMGMT from the same provider, and tries to export the key there if
necessary.
If an export of the key isn't possible (because the provider that
holds the key is an HSM and therefore can't export), we would simply
fail without looking any further.
This change modifies the behaviour a bit by trying a second fetch of
the operation implementation, but specifically from the provider of
the EVP_PKEY that's being used. This is done with the same properties
that were used with the initial operation implementation fetch, and
should therefore be safe, allowing only what those properties allow.
