For more generalisation, the default parameter values are now handled by
cdist instead of trying to get a value and use a default if parameter is
not given.
It handles the default values in a more general way, instead of write
one default in (possibly) multiple places.
Problem occurred when checking the 'state' parameter, which required to
set a default value in two places.
Without the == 1 all lines which contain --line as a substring match. e.g. if
--line is "line" and the file contains the line "wrong line" this was considered
a match.
PreOS code did not use configuration support. This fix adds support
for using cdist configuration, which takes into account cdist
configuration file, environment variables and command line options,
especially conf_dir.
It also adds support for -g, --config-file option, for specifying
custom configuration file.
This already takes care of setting up the base DN and managing it as well as
allowing for settings for the listener URLS.
The type was also made a singleton as it doesn't make much sense to setup
multiple LDAP servers on the same machine.
CDIST_ORDER_DEPENDENCY now defines type order dependency context.
cdist (emulator) maintains global state variables, as files,
order_dep_state and typeorder_dep, and per object state variable,
as file, typeorder_dep.
If order_dep_state exists then this defines that order dependency is
turned on.
If order_dep_state does not exist then order dependency is turned off.
If order dependency is on then objects created after it is turned on are
recorded into:
* global typeorder_dep, in case of init manifest
* object's typeorder_dep, in case of type's manifest.
If order dependency is on then requirement is injected, where object
created before current, is read from:
* global typeorder_dep, in case of init manifest
* object's typeorder_dep, in case of type's manifest.
Every time order dependency is turned off, typeorder_dep files are
removed, which means that type order list is cleared, context is
cleaned.
In the end cdist cleans after itself, i.e. mentioned files are removed.
When running type manifest is finished typeorder_dep file is removed.
When running config finishes global typeorder_dep and order_dep_state
files are removed.
Global type order recording is untouched.
Furthermore, for completeness, type order is now recorded for each object
too.
