For Python bindings PIDL wants the struct to be defined as public if we
want to use __ndr_print/pack/unpack.
Define the [public] attribute to ForestTrustCollisionInfo/Record to
allow easier debugging when there is collision in establishing a trust.
This change does not affect C code as NDR functions are always
generated, only not exposed in Python bindings.

Previous commits maintained the ordering between
ctdb_remove_orphaned_ifaces() and ctdb_vnn_unassign_iface(). This
meant that ctdb_remove_orphaned_ifaces() needed to steal the orphaned
interfaces and they would be freed later.
Unassign the interface first and things get simpler.
ctdb_remove_orphaned_ifaces() is now self-contained.

reloadips really expects deleted IPs to be released before completing.
Otherwise the recovery daemon starts failing the local IP check. The
races that follow can cause a node to be banned.
To make the error handling simple, do the actual deletion in
release_ip_callback().

It is hard to diagnose failures in the NFS tickle test because there's
no way of telling if the test node doesn't have the tickle or if it
didn't get propagated.
Factor out check_tickles() into local.bash and give it some
parameters.
Have the NFS test call it first to ensure the tickle has been
registered. Then use new function check_tickles_all() to ensure the
tickle has been propagated to all nodes. Give this a bit of extra
time (double the timeout) just in case we're racing with the update.
Add a useful comment to the CIFS test so that I stop asking myself how
the test could ever have worked reliably. :-)

"statd-callout notify" currently complains until an add-client or
del-client is done.
Given that we might use ctdb.tdb for something else in the future it
makes sense attach to it in the "startup" event. This could be done
in the background but it should be so lightweight that a timeout will
indicate serious problems.

Commit 0723fedced added a cheap
implemention of ctdb_control_startup() that simply flags the recipient
node as needing to send updates for each IP when the tickle update
loop next fires. Commit 026996550d
ensures that a node only sends tickle updates once being flagged to do
so.
CTDB_CONTROL_STARTUP is broadcast to all nodes, so this is a good
start. However, the tickle updates are only broadcast to connected
nodes. A recently started node may not yet be considered to be
connected because the keepalive monitoring loop may not yet have
marked the node as connected. This means that the tickle update loop
races with the keepalive monitoring loop. If the tickle update loop
wins then updates will not be sent to the recently started node.
The simplest improvement is to stop the tickle update from depending
on whether a node is connected or not. So instead of broadcasting
tickle updates to connected nodes, they are broadcast to all nodes.
Since no reply is expected, this should work just fine.
While looking at this code, ctdb_ctrl_set_tcp_tickles() is named like
a client function. It isn't a client function. Also, 2 of the
arguments are ignored. So rename this function to
ctdb_send_set_tcp_tickles_for_ip() and remove the ignored arguments.

Tests for xpnn need to implement a stub for ctdb_sys_have_ip(). The
cheapest way of doing this is to read a fake nodemap using the
existing code and check if the IP of the "current" node is the one
being asked about. However, the fake state initialisation isn't
currently available to without_daemon commands because it is meant to
represent daemon state. However, it can be made available by moving
the relevant code into a new stub for tevent_context_init(). The stub
still needs to initialise a tevent context - this can be done by
calling a lower level function.

Add another filter function, like the ones for capabilities and flags
to, for filtering by NAT gateway nodes. This makes the main
natgw_list function more readable.
Note that this drops the early filtering of disconnected nodes, so
they will now be listed in a NAT gateway group. This makes sense.

It looks like the original without_daemon code still tried to
establish a client connection to the daemon. Closing stderr looks to
be a cheap way of hiding the errors when this failed.
However, later cleanups avoid the client connection altogether, so do
not close stderr. Now debug output from without_daemon commands
actually appears.
