ccf4d78e04 - renamed ctdb_control utility to ctdb 
- use -n to specify node number in ctdb utility

- change 'ctdb status' to 'ctdb statistics'

- added 'ctdb status' which shows status

- added netmask to public IPs, so you don't try a takeover on a
  foreign network

- cleaned up tools/ctdb_control.c a lot

- generate usage message at runtime

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.

db4c479568 add dead node detection so that if a node does not generate any 
keepalive traffic for x seconds   it is deemed dead


this triggers a recovery after a while if a ctdbd has been STOPPED    
but it doesnt recover automatically when the node reappears
