Comment (by nickm):

 Design notes:

 I think that changing the meaning of accept/reject * to mean IPv4 only is
 too risky for 0.2.7.  I think we could safely have those continue to mean
 what they mean today.

 I think it's fine to do a NOTICE when * means "IPv4 and IPv6".

 I think accept6 * should mean "accept *6".

 Code notes:

 It seems like the TAPMP_IPV[46]_ONLY options won't actually stop any
 addresses that *don't* begin with a star.  That seems wrong. I would
 expect TAPMP_IPV4_ONLY to reject [FE80::]/16:80, for example.
