destroy the DBus interfaces.

Support to parse configuration files. By default, the default conf file
is parsed ({sysconfdir}/pinos/pinos.conf), but that can be changed with
an environment variable (PINOS_CONFIG_FILE). The file can contain
commands and assignments (no assignment supported this far).
Support for command module-load is added.
