    Port context query.

Parameter:
    policy          The policy to query.

Keyword Parameters/Class attributes:
    protocol        The protocol to match (socket.IPPROTO_TCP for
                    TCP or socket.IPPROTO_UDP for UDP)

ports           A 2-tuple of the port range to match. (Set both to
                    the same value for a single port)
    ports_subset    If true, the criteria will match if it is a subset
                    of the portcon's range.
    ports_overlap   If true, the criteria will match if it overlaps
                    any of the portcon's range.
    ports_superset  If true, the criteria will match if it is a superset
                    of the portcon's range.
    ports_proper    If true, use proper superset/subset operations.
                    No effect if not using set operations.

user            The criteria to match the context's user.
    user_regex      If true, regular expression matching
                    will be used on the user.

role            The criteria to match the context's role.
    role_regex      If true, regular expression matching
                    will be used on the role.

type_           The criteria to match the context's type.
    type_regex      If true, regular expression matching
                    will be used on the type.

range_          The criteria to match the context's range.
    range_subset    If true, the criteria will match if it is a subset
                    of the context's range.
    range_overlap   If true, the criteria will match if it overlaps
                    any of the context's range.
    range_superset  If true, the criteria will match if it is a superset
                    of the context's range.
    range_proper    If true, use proper superset/subset operations.
                    No effect if not using set operations.
