a4ebb6d5ef if a caller specifies a timeout when calling a control, it makes no
sense to have the daemon requeue the packets if they timeout or fail to 
deliver to the remote 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

5cb817f031 split the vnn broadcast address into two
one broadcast address for all nodes
and one broadcast address for all nodes in the current vnnmap

update all useage of the old flag to now only broadcast to the vnnmap
except for tools/ctdb_control where it makes more sense to broadcast to 
all nodes

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

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.

this is not optimized at all and copies/merges all records between

push only those records for which the node is lmaster)

9366120d92 changed the way set_call and attach are done so that you can safely
attach to databases after the protocol has started. The daemon
broadcasts information on new databases to the other daemons.

This also eliminates the need for the client to know about the hash
between db name and db_id.
