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

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

7bbcc964f2 add support in catdb to dump the content of a specific nodes tdb instead 
of traversing the full cluster.
this makes it easier to debug recovery

update the test script for recovery to reflect the newish signatures to
ctdb_control



the catdb control does still segfault however when there are missing 
nodes in the cluster   as there are toward the end of the recovery test

7dfdab1b9d recovery daemon 
this program is a client to the local ctdb daemon

every second it pulls all vnnmap and nodemaps from all nodes that are 
available and checks if a recovery is required

a recovery is required if :
* all nodes do NOT have an identical vnnmap and generation
* all nodes do NOT have an identical nodemap
* there are active nodes that are NOT in the nodemap
* there are nodes in the nodemap that are NOT active

During recovery,  the recovery tool will also make sure that all nodes 
know about and have created all databases.

e752f3bd97 - changed the REQ_REGISTER PDU to be a control 
- allow controls to know which client invoked them

- added a client_id to clients, so they can be identified remotely

- added the ability to remove registered srvids

- in the list_keys code, register a temp srvid, then remove it afterwards

2b1714a521 update getvnnmap control to take a timeout parameter 
dont explicitely free the vnnmap pointer in the getvnnmap control  this 
is freed by the mem_ctx instead

add code to the recoverd to detect when/if recovery is required
veiry that the number of active nodes, the nodemap and the vnn map is 
consistent across the entire cluster and if not   trigger a recovery 
(which right now just prints "we need to do recovery" to the screen.

ebc478749b start working on a recovery daemon 
change ctdb_control so it takes a timeval pointer as argument.
this is the timeout. if the node has not responded within hte timeout
ctdb_control will return an error instead of hanging.
if the timeval pointer is NULL then the call will block indefinitely if 
there is no response.

this is used for now in the createdb control   but all the helpers 
ctdb_ctrl_* should probably be updated to take a timeout parameter as 
well.

107d91e391 - when handling a record migration in the lmaster, bypass the usual 
dmaster request stage, and instead directly send a dmaster
  reply. This avoids a race condition where a new call comes in for
