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 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.

Use "ipreallocated" instead. The "stopped" event pre-dates the
"ipreallocated" event. The only way of stopping a node is via the
ctdb tool, which explicitly causes a takeover run to occur after the
node is stopped. The takeover run will generate an "ipreallocated"
event.

The current logic is horrible and creates an unnecessary file. Let's
make the script debug level independent of ctddb's debug level.
* Have debug() use $CTDB_SCRIPT_DEBUGLEVEL directly
* Remove ctdb_set_current_debuglevel()
* Remove the "getdebug" command from ctdb stub in eventscript unit
tests
* Update relevant eventscript unit tests to use
$CTDB_SCRIPT_DEBUGLEVEL

"ctdb ping" can time out. How many times should we try?

(This used to be ctdb commit 90cb337e5ccf397b69a64298559a428ff508f196)
Using "ctdb ping" and "ctdb status" is fraught with danger. These
commands can timeout when ctdbd is running, leading callers to believe
that ctdbd is not running. Timeouts could be increased but we would
still have to handle potential timeouts.
Everything else in the world implements the "status" option by
checking if the relevant process is running. This change makes CTDB
do the same thing and uses standard distro functions.
This change is backward compatible in sense that a missing
/var/run/ctdb/ directory means that we don't do a PID file check but
just depend on the distro's checking method. Therefore, if CTDB was
started with an older version of this script then "service ctdb
status" will still work.
This script does not support changing the value of CTDB_VALGRIND
between calls. If you start with CTDB_VALGRIND=yes then you need to
check status with the same setting. CTDB_VALGRIND is a debug
variable, so this is acceptable.
This also adds sourcing of /lib/lsb/init-functions to make the Debian
function status_of_proc() available.
