TED update - 18: adding new TE-Link address based index

Added #new #address #based #indexing on the #TE-Link in the TED module. This will enable to #query TE-Links #based on their configured #address (i.e. #IPv4, #IPv6 or #un-numbered). This will be useful in many parts of the system as external to the stack the TE-Links are always identified by their assigned address. Support has been added for #multi-address scenario on the same TE-Link.
