- changed modules.c calling conventions to be interface-based

- moved module loader from conf.c to module.c, where it belongs
- made the necessary plumbing to auto-load library modules
- upgraded debug system to include iRet in function exit message
- changed module interface so that instances need only to be supported by
    output plugins (if we actually need them for input plugins, we can
    always add it again...)
- milestone: first implementation of library modules (but do not get
    unloaded on exit/hup so far)
