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.

In other news, did you know ctime() returns a \n-terminated string?

We also no longer return an error before scripts have been run; a special
zero-length data means we have never run the scripts.
"ctdb scriptstatus all" returns all event script results.

We're going to allow fetching status of all script runs, so this
name is no longer appropriate.

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 unifies code paths and simplifies things: we just hand -ENOEXEC to
ctdb_ctrl_event_script_stop().

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.

The -f option allows an alternate nodes file to be specified,
overriding the CTDB_NODES_FILE environment variable.
The -n option allows hostnames to be used instead of node numbers.
Using a range of hostnames is invalid, so hostnames can't contain
hyphens ('-') - sorry! You can use this option without a nodes file
by specifying "-f /dev/null".

master to perform an explicit ip reallocation.
This is more reliable and faster than having the recovery dameon track these
changes, and since we now have an explicit method to ask the recovery daemon
to perform an explicit ip reallocation, we should use this.

This is useful when we are moving addresses using moveip in the cluster since otherwise if we collide with the recovery daemons own check we could cause a recovery

In testing and other situations (e.g. eventscripts) it is necessary to
select a node where a ctdb command can be run. The whole idea here is
to avoid nodes where ctdbd is not running and where most ctdb commands
would fail. This implements a standard way of doing this involving a
recursive onnode command.
There is still a small window for a race, where the selected node is
suddenly shutdown, but this is unavoidable.
