This does not modify any behaviour of the daemon itself other than showing this flag as ON in the ctdeb getcapabilities output
(This used to be ctdb commit fb337c151bd16ad5ad0c99431224451979d8c651)
This event is called when a node is stopped and is used by eventscripts that need to do certain cleanup and removal of configuration or ip addresses or routing ...
Note that a STOPPED node is considered "inactive" and as such will not be running the "recovered" event when the rest of the cluster has recovered.
(This used to be ctdb commit 65e9309564611bf937ded3c74a79abff895d7c59)
also verify that we actually do have a natgw master available if this is configured and make the node unhealthy if not.

* Move building of CTDB_OPTIONS to new function build_ctdb_options()
and have it use a helper function for readability.
* New functions check_persistent_databases() and set_ctdb_variables().
* Remove valgrind-specific stop code, since the general pkill should
kill ctdbd when running under valgrind.
* Remove some bash-isms (e.g. >& /dev/null) since the script is /bin/sh.
* Make indentation consistent.
* Minor clean-ups.

The valgrind start case should not use daemon, since this is specific
to Red Hat.

Use a local variable $ctdbd so that we always run ctdbd from the the
same place and so that we know what to kill. This variable respects
the $CTDBD environment variable, which may be used to specify an
alternative location for the daemon.
In the important cases use "pkill -0 -f" to check if ctdbd is
running. Also, remove the special case for killing ctdbd when running
under valgrind. The regular case will handle this just fine.

Add a helper function that checks whether a unix domain socket exists
and there is a daemon LISTENING to it similar to the existing function
to check for a daemon LISTENING to a tcp/ip socket.

RHEL5 can SIGKILL httpd when stopping it, causing it to leak
semaphores. This means that eventually a node runs out of semaphores
and httpd can't be started. So, before we attempt to start httpd we
clean up any semaphores owned by apache. We also try to restart httpd
in the monitor event if httpd has gone away.

We want ctdb to shutdown first, as it manages many other
services. With the old level of 32 the NFS service would shutdown
first, and that would trigger ctdb to do a recovery. Then ctdb itself
would be shutdown a few seconds later, which causes a lot of error
messages in the other nodes logs
(This used to be ctdb commit 2f952af1a12e81a652ec9a4794db96f9593f2676)
This would allow a sysadmin to set up ctdb to send an email/snmptrap/... when the status of the node changes.

This can take very long if there are very many shares and is in that case better to implement in a separate cronjob than in ctdb eventscript
(This used to be ctdb commit 432604a1435cd2b5a7178fb5aedf1d4b61bffeb9)
this is a timeconsuming process and might not be feasible to perform if there are very many thousand shares

The httpd service on suse and ubuntu/debian systems is usually
called "apache2" nowadays.
Note: There are older installs with Apache 1.3 out there, in which case
the service is called "apache". An extra check for these installs could
be useful as a sequel to this patch...

The netstat test only grepped for the ipv4 wildcard address.
Now the ipv6 wildcard listener is correctly detected as well.

This fixes tcp port monitor events on systems, where netcat or nc
is not found in /usr/bin/, Debian, for instance.
The patch also separates the process of finding the binaries and
calling them, moving the detection outside of the loop over the
ports list.
