[PULL 23/52] ui/console: specialize console_lookup_unused()

[marcandre . lureau]

From: Marc-André Lureau <marcandre.lur...@redhat.com>

graphics_console_init() is expected to return a graphic console.

The function doesn't need to be exported.

We are going to specialize further QemuGraphicConsole & QemuTextConsole.
The two will not be interchangeable anymore.
