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.

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.

Found during automatic regression testing.
We do not allow the takeip/releaseip events to be executed during a recovery.
All of "ctdb addip, ctdb delip, ctdb moveip" use and force these events to
trigger to perform the ip assignments required.
If these commands collide with a recovery, these commands could fail since we do
not allow takeip/releaseip events to trigger during the recovery.
While it is easy to just try running hte command again, this is suboptimal for script use.

In some contexts ctdb_diagnostics generates too many errors when it is
run on heterogeneous and machine-configured clusters. In some
clusters some nodes are expected to be differently configured and also
machine-generated configured files can have comments containing
timestamps.
This adds some command-line options that can be used to reduce the
number of errors reported:
-n <nodes> Comma separated list of nodes to operate on
-c Ignore comment lines (starting with '#') in file comparisons
-w Ignore whitespace in file comparisons
--no-ads Do not use commands that assume an Active Directory Server
The -n option simply allows ctdb_diagnostics to operate on a subset of
nodes, avoiding file comparisons with and data collection on nodes
that are differently configured. For file comparisons, instead of
showing each file on the current node and then comparing other nodes
to that file, the file from the first (available or requested) nodes
is shown and then other nodes are compared to that. That has resulted
in changes in output - that is, ctdb diagnostics no longer prints
messages referencing the current node.
-c and -w are used to weaken comparisons between configuration files.
--no-ads can be used to avoid running ADS-specific commands if a
cluster uses LDAP (or other non-ADS) configuration.
This also fixes a number of bugs in related code:
* A call to onnode was losing the >> NODE ... << lines because they
now go to stderr. This was changed in onnode long ago but
ctdb_diagnostics was never updated to match.
* ctdb_diagnostics was counting lines in /etc/ctdb/nodes to determine
what nodes to operate on. For some time the nodes file has
supported syntax that makes this invalid. "ctdb listnodes -Y" is
now used to list available nodes.

In that case, when the main daemon is not running
the ctdb context will be initialized to NULL, since we can not connect.
Move the calls to read the ctdb socketname and connecting via libctdb to
only happen when we are executing a "ctdb ..." command that requires that we talk to the actual daemon.
Otherwise we will get an ugly SEGV for the "ctdb ..." commandline tool
when trying to run a command that is supposed to work also when the daemon is down.

ctdb_client.h is the existing internal client interface (which was mainly
in ctdb.h), and ctdb_protocol.h is the information needed for the wire
protocol only.
ctdb.h will be the new, shiny, libctdb API.

This might not be sufficient if there are several recoveries in a row.
Instead loop as long as it takes for the recovery master to finish the recoveries and re
spond to the ipreallocate call.
Increase the log level of the error message when the recovery master was busy and could
not perform the ipreallocation promptly

2 changes:
* If a relative nodes file is specified via -f or $CTDB_NODES_FILE but
this file does not exist then try looking for the file in /etc/ctdb
(or $CTDB_BASE if set).
* If a nodes file is specified via -f or $CTDB_NODES_FILE but this
file does not exist (even when checked as per above) then do not
fall back to /etc/ctdb/nodes ((or $CTDB_BASE if set). The old
behaviour was surprising and hid errors.

Rather than ignoring deleted event scripts (or pretending that they were "OK"),
and discarding other stat errors, we save the errno and turn it into a negative
status.
This gives us a bit more information if we can't execute a script (eg.
too many symlinks or other weird errors).

This starts the move toward more expressive encoding of return values:
positive values mean the script ran, negative means we had a problem with
the script (and the value is the errno).
This does timeout, but changes the ctdb tool to recognize it.
