Change subject: add osmo-mgw --vty-ref-xml: dump VTY ref XML to stdout
......................................................................

add osmo-mgw --vty-ref-xml: dump VTY ref XML to stdout

Add only a long option to not clutter the cmdline namespace.

To add a long option without a short letter is slightly complex: use the 'flag'
and 'val' mechanism as in 'man 3 getopt' to write an option index to
long_option.
