Several of the attribute values defined for use by attribute certificates
use multi-valued data in an ASN.1 SEQUENCE. Allow reading of these values
from a configuration file, similar to how generic X.509 extensions are
handled.

Only fields that are allowed by RFC 5755 are
accessible through this API. Fields that are only supported
in version 1 attribute certificates (e.g. the AttCertIssuer
v1Form fields) are not implemented.

Add support for attribute certificates (v2) as described
in RFC 5755 profile.
Attribute certificates provide a mechanism to manage authorization
information separately from the identity information provided by
public key certificates.
This initial patch adds the ASN.1 definitions
and I/O API. Accessor functions for the certificate fields
will be added in subsequent patches.
