This introduces changes that are part of 4.0 cleanup in updater and updater package.
Primarily configuration is changed and legacy scripts are dropped.
Together with this changes in Foris-controler should be made. There should be no huge change in API from Foris point of view with exception that for 3.x vs 4.x compatibility it should start using autorun module in svupdater instead of changing uci configuration directly. @shenek
The only API change that is there is in userlists. Those were renamed to more appropriate pkglists. Module name lists stayed same but there is new variant of same function name and it is suggested that Foris should migrate to that.
