[PULL 24/26] gtk: Add show_menubar=on|off command line option.

[Gerd Hoffmann <kraxel@redhat.com>]

From: Bryce Mills <brycemills@proton.me>

The patch adds "show_menubar" command line option for GTK UI similar to
"show_tabs". This option allows to hide menu bar initially, it still can
be toggled by shortcut and other shortcuts still work.
