freeswitch: Move usage description out of main() and improve cmdline option handling. 

Move empty cmdline option string check and "-help/-h/-?" handling to top of loop.

Emit a proper error message for unknown options. (Just displaying the
usage description, but not telling the user which option was wrong, is bad mojo).
