X.509: Embed public_key_signature struct and create filler function
Embed a public_key_signature struct in struct x509_certificate, eliminating now unnecessary fields, and split x509_check_signature() to create a filler function for it that attaches a digest of the signed data and an MPI that represents the signature data. x509_free_certificate() is then modified to deal with these. Whilst we're at it, export both x509_check_signature() and the new x509_get_sig_params().
