e21f69107f yay! finally fixed the bug that volker, ronnie and I have been chasing 
for 2 days.

The main bug was in smbd, but there was a secondary (and more subtle)
bug in ctdb that the bug in smbd exposed. When we get send a dmaster
reply, we have to correctly update the dmaster in the recipient even
if the original requst has timed out, otherwise ctdbd can get into a
loop fighting over who will handle a key.

This patch also cleans up the packet allocation, and makes ctdbd
become a real daemon.

21331d3c94 ctdb will now verify that the generation id for all CTDB_REQ_CALLs that 
it receives from remote nodes with its own generation number.

if the generation id do not match the daemon will just discard the 
packet completely.
this will require that clients such as samba3 will have to be aware that 
calls it sends to remote nodes may get lost and will have to resend the 
requests after a timeout.

during cluster recovery/reconfiguration the generation nnumbers will be 
changing and this can be used to prevent nodes that are still in the 
"old" instance from talking to nodes that belong to the new generation 
instance

f616f2de10 add a special VNN that means "all" nodes so that a message can be 
broadcasted to all daemons in the cluster

change the message dispatch routine for sending messages so that it 
allows several clients to use the same srvid
messages are then passed on to all clients that have that srvid

initialize the vnn table based on number of nodes for now.
later when recovery is implemented the recovery process will populate 
this mapping table.
