    core: Use 0 for unset port value, rather than -1
    
    This is a work around for a weird problem that class initialization of
    CmdlineCnfig is happening after one of it's static methods is called. It
    seems like a Vala bug at first but I failed to reproduce this with a
    simple test case.
