Merge branch 'tipc-addr' into iproute2-next

Merge branch 'tipc-addr' into iproute2-next

Jon Maloy  says:

====================

1: We introduce ability to set/get 128-bit node identities
2: We rename 'net id' to 'cluster id' in the command API,
   of course in a compatible way.
3: We print out all 32-bit node addresses as an integer in hex format,
   i.e., we remove the assumption about an internal structure.
