Some of these just aim to load the generic script.options file while

This allows other scripts to use the given options for a particular
event script. One interesting example is that the ctdb_natgw tool
should look for configuration in events.d/11.natgw.options.
In the future this will be something like
events/failover/11.natgw.options, so require the component to be
specified even though it isn't yet used.
Test support is also updated.

Volatile databases now have their own subdirectory. This makes things
easier if we later recommend mounting a tmpfs on the volatile database

No need to create database directories for local daemon tests. ctdbd
will do that.

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.
