[Qemu-devel] [PATCH 1/3] console: add API to get underlying gui window ID

[Samuel Thibault]

This adds two console functions, qemu_console_set_window_id and
qemu_graphic_console_get_window_id, to let graphical backend record the
window id in the QemuConsole structure, and let the baum driver read it.
