425b3c56c6 - create /etc/ctdb/taken_ips and /etc/ctdb/changed_ips analog to the 
existing /etc/ctdb/released_ips

- only call the statd-callout script if the ips have changed  and call 
it with a "notify" argument.    we need to restart nfslock service in 
both cases

- change statd-callout to explicitely restart the lock manager and statd 
when "notify" is called.   copy the state directory for each held ip 
from shared storage to /tmp then use sm-notify to send notifications to 
all monitored clients

d41290fbae added code to ctdb to send a tcp 'tickle' ack when we takeover an 
IP. A raw tcp ack is sent for each tcp connection held by clients
before the IP takeover.

These acks have a deliberately incorrect sequence number, and should
cause the windows client to send its own ack which will in turn cause
a tcp reset and thus cause windows clients to much more quickly
reconnect to the new node.

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

39d81cffb1 recovery daemon with recovery master election 
election is primitive, it elects the lowest vnn as the recovery master

two new controls, to get/set recovery master for a node



to use recovery daemon,   start one  
./bin/recoverd --socket=ctdb.socket*
for each ctdb daemon


it has been briefly tested by deleting and adding nodes to a 4 node 
cluster but needs more testing

If we discover that some node is still in recoverymode it may indicate 
that a previous recovery ended prematurely and thus we should start a 
new recovery
