Add support for custom signature parameters
Many signature types define the digest and public key type by a single OID
such as ecdsa_with_sha256.
Some types (RSA-PSS for example) use a single OID to indicate the signature
scheme and additional parameters are encoded in the AlgorithmIdentifier.
Add an X509_SIG_INFO structure to contain details about the signature type:
specifically the digest algorithm, public key algorithm, security bits and
various flags. This supports both existing algorithms and more complex
types.
Add accessors for the structure and a special case that retrieves signature
information from a certificate.
