Check the set type received from the kernel (typename, revision, family) against the userspace types looking for a matching type.

Returns the set type for success and NULL for failure.

ipset_type_get - get a set type from the kernel : session structure : the command which needs the set type

Build up and send a private message to the kernel in order to get the set type. When creating the set, we send the typename and family and get the supported revisions of the given set type. When adding/deleting/testing an entry, we send the setname and receive the typename, family and revision.

Returns the set type for success and NULL for failure.
