CTDB needs the legacy/00.ctdb event script to be able to function
properly. If this script is not enabled then assume a first-time
install or an upgrade to a version that requires events scripts to be
enabled via symlinks. In these cases enable this script and other
commonly used scripts.
Remove links during uninstall (but not during upgrade).

Only do this for a direct install. If DESTDIR is being used then
assume a package is being built and let the packager handle this case.

This is no longer needed because inactive/disabled nodes no longer
report any available public IP addresses.

This can be done now that NoIPHostOnAllDisabled is gone and will allow
the public IP address failover logic to be simplified.
In the test code, still filter available IP addresses by node state.
This code can't currently read information about available IP
addresses but that will change in future

Defaulting to host public IP addresses when all nodes are unhealthy
does not obey the principle of least surprise. It has caused much
confusion over the years. It often leads to problems when all nodes
are unhealthy due to something like a cluster filesystem being
unmounted.
Change the default value for this tunable as the first step of
completely removing this behaviour.
Remove tests that set NoIPHostOnAllDisabled=1 and update the expected
result for other tests where no nodes are healthy.

Even the monitor event runs update_tickles(), which needs public IP
addresses and FAKE_CTDB_NUMNODES to be initialised. Currently this
works by default but soon we'll need FAKE_CTDB_NUMNODES in another
context.

From this patch onwards, CTDB daemon is broken till the client code for
new eventd is integrated. This requires getting rid of the old eventd
protocol and client code and then switching to the new eventd protocol

Setting DEBUGLEVEL before calling debug_init() causes segmentation
violation with gcc8. DEBUGLEVEL_CLASS is statically initialized to
debug_class_list_initial which is defined as const. Only after
debug_init() is called, DEBUGLEVEL_CLASS becomes a talloc'd array.
So before modifying DEBUGLEVEL, ensure debug_init() is called via
setup_logging(). (debug_init is a static function.)
