Subject: [PATCH net-next 00/12] tipc: make use of kernel threads to simplify things

The biggest change here is the one where we make use of the fact
that linux supports kernel threads and do the server like operations
within kernel threads.  As Jon says:  

   We remove the last remnants of the TIPC native API, to make it
   possible to simplify locking policy and solve a problem with lost
   topology events.
 
   First, we introduce a socket-based alternative to the native API.

   Second, we convert the two remaining users of the native API, the 
   TIPC internal topology server and the configuarion server, to use the
   new API. 

   Third, we remove the remaining code pertaining to the native API.

We also ditch another Kconfig parameter, in favour of having it being
able to be set at boot/module load time vs requiring a reconfig/recompile.

In addition, there is a follow up to fix an issue that Neil had
highlighted during the previous round of TIPC commits.

I've tested this collection of commits between 32 and 64 bit x86
machines using the standard tipc test suite.

Paul.
