26fc2ebd4b update the documentation for NFS to mention that the lock manager must
run on the same port on all nodes.

remove the CTDB_MANAGES_NFSLOCK variable that is no longer used

d81bca2072 make it possible to specify how many times ctdb killtcp will try to RST
the tcp connection

change the 60.nfs script to run ctdb killtcp in the foreground so we 
dont get lots of these running in parallel when there are a lot of tcp 
connections to rst

dbc66d054b dont restart the tcp service after a ip takeover, it is more efficient
to just kill off the tcp connections

a859723912 nicer handling of DISCONNECTED flag when we update the node flags from
a remote message

69f3a09e6f when a remote node has sent us a message to update the flags for a node,
dont let those messages modify the DISCONNECTED flag.

the DISCONNECTED flag must be managed locally since it describes whether 
the local node can communicate with the remote node or not

b871c3e365 a better way to fix the DISCONNECT|BANNED vs DISCONNECT bug

3499c8c673 when checking the nodemap flags for consitency while monitoring the
cluster,   we cant check that both the BANNED and the DISCONNECTED flags 
are both set at the same time   since if a node becomes banned just 
before it is DISCONNECTED   there is no guarantee that all other nodes 
will have seen the BANNED flag.

So we must first check the DISCONNECTED flag only   and only if the 
DISCONNECTED flag is not set should we check the BANNED flag.


othervise this can cause a recovery loop while some nodes thing the 
disconnected node is DISCONNECTED|BANNED and other think it is just 
DISCONNECTED
