At the moment, when someone deletes all the IPs on a node, all we see
are the release IP messages and we have to guess why.
Some would argue that add/release are more significant than
take/release so they should be logged.

fff88940f71058e4eefd65f50a6701389c005c17 introduced a regression.
Without $service_name set by default, the CTDB configuration is no
longer loaded when loadconfig() is called without any arguments.
That's bad.

This is really a check to see if a node is already hosting IPs. If
so, we assume it was previously healthy so it isn't considered as a
rebalance candidate. There's no need to limit this to healthy node,
since this is checked elsewhere.
Due to this the variable newly_healthy is renamed everywhere to
rebalance_candidates.
The mask argument is now completely unused.

This really needs to be per-node. The rename is because nodes with
this tunable switched on should drop IPs if they become unhealthy (or
disabled in some other way).
* Add new flag NODE_FLAGS_NOIPHOST, only used in recovery daemon.
* Enhance set_ipflags_internal() and set_ipflags() to setup
NODE_FLAGS_NOIPHOST depending on setting of NoIPHostOnAllDisabled
and/or whether nodes are disabled/inactive.
* Replace can_node_servce_ip() with functions can_node_host_ip() and
can_node_takeover_ip(). These functions are the only ones that need
to look at NODE_FLAGS_NOIPTAKEOVER and NODE_FLAGS_NOIPHOST. They
can make the decision without looking at any other flags due to
previous setup.
* Remove explicit flag checking in IP allocation functions (including
unassign_unsuitable_ips()) and just call can_node_host_ip() and
can_node_takeover_ip() as appropriate.
* Update test code to handle CTDB_SET_NoIPHostOnAllDisabled.

(This used to be ctdb commit d9775fcbd6e30eef8382bea68e2f9bad2309f2c1)
This is intended to replace nfs_check_rpc_service(), which builds
configuration into eventscripts.
nfs_check_rpc_services() uses a directory of configuration checks that
can be edited by an administrator. The files have one limit check and
a set of actions per line. The program name is extracted from the
file name.

This has 2 advantages:
1. It uses get_tcp_connections_for_ip() to check for leftover
connections, instead of custom code.
2. It checks for the timeout condition before sleeping. The current
code sleeps and then checks, so wastes a second.

Complicated argument handling was introduced to deal with multiple
services per eventscript. This was a failure and we split 50.samba.
This simplifies several functions to use global $service_name
unconditionally instead of having an optional argument.
$service_name is no automatically longer set in the functions file.
This means it needs to be explicitly set in 13.per_ip_routing because
this script uses ctdb_service_check_reconfigure().
Eventscript unit test infrastructure needs to set $service_name during
fake service setup, and policy routing tests need to be updated
accordingly.
