extcap: Cleanup complex types and add save option

Cleanup handling of complex data types and use only
glib defined datatypes while handling argument values.

Add a save parameter, which (additionally) can set, that
a parameter is not saved in a configuration file. Passwords
are by default not saved, which may be overwritten using
this parameter
