MINOR: acl: add types to ACL patterns
We cannot currently match IPv6 addresses in ACL simply because we don't
support types on the patterns. Let's introduce this notion. For now, we
rely on the SMP_TYPES though it doesn't seem like it will last forever
given that some types are not present there (eg: regex, meth). Still it
should be enough to support mixed matchings for most types.
We use the special impossible value SMP_TYPES for types that don't exist
in the SMP_T_* space.
