[lwip-users] ip6_addr_ismulticast_ doesn't allow for transient multicast address

[Ian]

If I read RFC1884 (section 2.6) correctly the ip6_addr_ismulticast_*
macros need to allow for the T-bit=1 indicating that a transient
multicast address is being used. The following diff shows the changes
I've made locally.

Regards,

Ian
