ipv6: updates to privacy addresses per RFC 4941.
Update the code to handle some of the differences between RFC 3041 and RFC 4941, which obsoletes it. Also a couple of janitorial fixes. - Allow router advertisements to increase the lifetime of temporary addresses. This was not allowed by RFC 3041, but is specified by RFC 4941. It is useful when RA lifetimes are lower than TEMP_{VALID,PREFERRED}_LIFETIME: in this case, the previous code would delete or deprecate addresses prematurely. - Change the default of MAX_RETRY to 3 per RFC 4941. - Add a comment to clarify that the preferred and valid lifetimes in inet6_ifaddr are relative to the timestamp. - Shorten lines to 80 characters in a couple of places.
