This code tried to find the recovery master and send an ipreallocate
request to that node. When a node is stopped, this code asked the
stopped node for recovery master. Stopped node does not have up-to-date
information on the current recovery master. So ipreallocate requests
were sent to the wrong node and ignored by that node which is not the
recovery master.
Send ipreallocate request to all active nodes. That way we guarantee
that the current recovery master will see it and respond to it.

This is very much like "ctdb status" but actually returns the status
for use in scripts.
This can be used in 2 modes:
* An optional nodestring is passed directly to the command without
using -n. In this mode the current node is asked for the status of
all listed nodes.
* The nodestring is passed via -n. In this mode the designated nodes
will be asked for their status. This is like "ctdb status".
These modes can be mixed. For example:
ctdb nodestatus 1,2,3 -n 0
asks node 0 for the status of nodes 1, 2 and 3, returning the bitwise
OR of their statuses.
This version uses the auto_all functionality, so the output isn't
necessarily pretty. An improved version that does its own -n
processing may appear soon.

Centralise -n nodestring parsing and add the ability to pass a
comma-separated list of node numbers. Listing a node that is
disconnected or deleted results in failure, similar to the way passing
a single node currently works. All of the auto_all commands inherit
this functionality. For now, the non-auto_all commands do not inherit
this - they need to be individually tweaked. Therefore, we haven't
updated the documentation to advertise this feature.
Implemented via a new function parse_nodestring() that parses an
optional (pass NULL when not available to indicate "current node")
comma-separated list of node numbers or "all". parse_nodestring() can
be told to be non-fatal for disconnected/deleted nodes so it can also
be used in other contexts (yes, coming soon). main() is changed to
call this function.
A new magic PNN value CTDB_MULTICAST is added and along with a
corresponding option.nodes structure member (a talloc-ed array of
PNNs). This is also populated for "all" as well.
control_status() has new function pretty_print_flags() factored out so
pretty-printed flags can be used in error/debug messages. New
function is_partially_online() is also factored out - this simplifies
some of the logic.

This puts the parsing and checking logic close together. This makes

Most of the action in main() happens inside a for loop and an if
statement. This causes 2 levels of extra indent for the code and
makes it harder to read.
Instead, the current body of the loop is put below the loop and its
corresponding failure check.

Current behaviour is for onnode to timeout (for about 20s) for each
attempted ssh to a down node. With 40 or 50 invocations of onnode
this takes a long time.
2 changes to work around this:
* If EXTRA_SSH_OPTS (which is passed to ssh by onnode) does not
contains a ConnectTimeout= setting then add a setting for a 5 second
timeout.
* Filter the nodes before starting any diagnosis, taking out any "bad
nodes" that are uncontactable via onnode.
In the nodes summary at the beginning of the output, print
information about any "bad nodes".

that tries to bind to the specified port on INADDR_ANY.
This can be used for testing if a service is listening to that port or not.
Errors are printed to stdout and the returned status code is either 0 : if we managed to bind to the port (in which case the service is NOT listening on that bort) or the value of errno that stopped us from binding to a port.
errno for EADDRINUSE is 98 so a script using this command should check the status code against the value 98.
If this command returns 98 it means the service is listening to the specified port.
