====================
tipc: slim down name table

We clean up and improve the name binding table:

 - Replace the memory consuming 'sub_sequence/service range' array with
   an RB tree.
 - Introduce support for overlapping service sequences/ranges

 v2: #1: Fixed a missing initialization reported by David Miller
     #4: Obsoleted and replaced a few more macros to get a consistent
         terminology in the API.
     #5: Added new commit to fix a potential string overflow bug (it
         is still only in net-next) reported by Arnd Bergmann
