CTDB has no business mounting filesystems. Instead, documentation
for the new configuration system will include a recommendation that a
tmpfs be mounted on the volatile database directory.

Volatile databases now have their own subdirectory. This makes things
easier if we later recommend mounting a tmpfs on the volatile database
directory, rather than supporting the current CTDB_DBDIR=tmpfs magic.
No need to create database directories for local daemon tests. ctdbd
will do that.

Using CTDB_SET_TunableVariables in the main configuration file is no

loadconfig() currently tries to load the CTDB configuration and also
any system configuration relevant to the current (event) script.
Instead add a new function load_system_config() to load the
distribution-specific system configuration for a component. Call this
directly in the rare scripts that need the system configuration.
Also call load_system_config when loading the CTDB configuration to
pull in anything from the CTDB system configuration. This is partly
for backward compatibility but also to get options that can be used
anywhere.
loadconfig() no longer takes an argument. It simply loads the CTDB
configuration.
Drop support for falling back to /etc/ctdb/sysconfig/ctdb (or
similar). Surely there's nobody who uses that!
Also, drop the indirection where loadconfig() calls _loadconfig().
This was used years ago as a test hook and is no longer required.
Inexplicably, this change introduces a new shellcheck test failure, so
silence this.

This allows state directories for scripts other than services.
ctdb_setup_state_dir() takes 2 mandatory arguments.
Unlike ctdb_setup_service_state_dir(), this does not print the
directory name but sets a global variable. The intention is to go
back to a more sensible style of usage.
This will require a shellcheck directive before the first use, such
as:
# Set by ctdb_setup_state_dir
# shellcheck disable=SC2154
foo="${script_state_dir}/bar"
An alternative would be something like the following, which tricks
shellcheck into believing the variable is set:
ctdb_setup_state_dir "service" "foo"
# Shellcheck
script_state_dir="$script_state_dir"
However, this is more cryptic.

This is an optimisation that can cause incorrect results. If ctdbd
was killed and there is a stale PID file then this will often cause
"CTDB exited during initialisation". The wrapper reads the old PID
from the PID file, finds the PID gone, complains and exits.
It is better to drop this code and finally get this right. If ctdbd
does exit early then it will take CTDB_STARTUP_TIMEOUT (default 10)
seconds before the wrapper fails. That's not too bad...
