tipc: Hide media-specific addressing details from generic bearer code
Reworks TIPC's media address data structure and associated processing routines to transfer all media-specific details of address conversion to the associated TIPC media adaptation code. TIPC's generic bearer code now only needs to know which media type an address is associated with and whether or not it is a broadcast address, and totally ignores the "value" field that contains the actual media-specific addressing info. These changes eliminate the need for a number of endianness conversion operations and will make it easier for TIPC to support new media types in the future.
