762d4be8f9 add a helper that waits until the clueter is no longe rin recovery mode and return the generation number.
change the ban/unban logic to wait until we are not in recovery before it bans/unbans the node.

also wait until after the cluster has recovered from the ban/unban before returning so that the cluster is in recpovery mode == normal when the command returns.  this makes it much easier to script things ...

e54347fa4e redo and update how we synchronize flags across the cluster.
this simplifies the code and should close a race condition between the local recovery daemon and a remote node when flags are changing.

edb7241c05 redesign how reloadnodes is implemented.
modify the transport methods to allow to restart individual connections
and set up destructors properly.

only tear down/set-up tcp connections to nodes removed from the cluster
or nodes added to the cluster.
Leave tcp connections to unchanged nodes connected.

make "ctdb reloadnodes" explicitely cause a recovery of the cluster once
the files have been realoaded

51cc8b4df8 make it possible to delete an ip from all nodes at once using
"ctdb delip x.x.x.x -n all"

This is not as straightforward as one might think since during the
delete process we don not want the ip to be bouncing from one node to
another as node by node deletes it.

Thus we first delete the ip from all connected nodes which are not
currently hosting it.

After this we delete the ip from the node which is hosting it.

8b19b74325 onnode changes. "ok" is an alias for "healthy", "con" is an alias for
"connected".  Allow "rm" or "recmaster" to be a nodespec for the
recovery master. Better error handling for interaction with ctdb
client.

a92de86c2f When in verbose mode with -p, each line is prefixed with the node
address/name.  To implement this stderr has redirected to stdout -
this doesn't need to be done but is the simplest implementation.
Remove -t option since it doesn't seem to accomplish much but causes
spurious messages to be displayed by ssh.  Add explicit -h and --help
options.  Make style of usage message consistent with documentation.
Document new features in doc/onnode.1.xml.

in the recovery daemon when we check that the public ip address
allocation on the local node is correct (we have the ips we should have
and we dont have any we shouldnt have) use ctdb uptime and check the
recovery start/stop times and make sure we dont check for ip allocation
inconsistencies during a recovery  where the ip address allocation is in flux.
