9eeb4f1a51 we must bump the rsn everytime we do a REQ_DMASTER or a REPLY_DMASTER 
to make sure that the "merge records based on rsn during recovery" will
merge correctly.

this is extra important since samba3 never bumps the record when it 
writes new data to it !

f8765b19bf - got rid of the complex hand marshalling in the recovery controls 
- fixed the re-send of ctdb calls after a generation change

- fixed a reqid idr leak in controls

- removed the write_record test code

- use the new nonblock lockall code to prevent ctdbd from ever doing a
  blocking lock that could deadlock with smbd

- moved more of the recovery controls into ctdb_recover.c

a1866c6eeb hang the timeout event off state and thus we dont need to explicitely 
free it   and also we wont accidentally return from the function without 
killing the event first

6bfb5f61ca it now works to talloc_free() the timed event if we no longer want it to 
trigger

this must have been a sideeffect of a different bug in the recoverd.c 
code that has now been fixed

ad41dff7bf add a ifdeffed out block to the call. 
we really should kill the event in case the call completed before the 
timeout   so that we can also make timed_out non-static

4f2cdc2d8b hte timed_out variable needs to be static and can not be on the stack 
since if the command times out and we return from ctdb_control   we may 
have events that can trigger later which will overwrite data that is no 
longer in our stackframe

5cb817f031 split the vnn broadcast address into two

all nodes
