Akihiko Odaki c821a58ee7 ui/console: Pass placeholder surface to displays 
ui/console used to accept NULL as graphic console surface, but its
semantics was inconsistent among displays:
- cocoa and gtk-egl perform NULL dereference.
- egl-headless, spice and spice-egl do nothing.
- gtk releases underlying resources.
- sdl2-2d and sdl2-gl destroys the window.
- vnc shows a message, "Display output is not active."

Fortunately, only virtio-gpu and virtio-gpu-3d assign NULL so
we can study them to figure out the desired behavior. They assign
NULL *except* for the primary display when the device is realized,
reset, or its scanout is disabled. This effectively destroys
windows for the (uninitialized) secondary displays.

To implement the consistent behavior of display device
realization/reset, this change embeds it to the operation
switching the surface. When NULL was given as a new surface when
switching, ui/console will instead passes a placeholder down
to each display listeners.

sdl destroys the window for a secondary console if its surface is a
placeholder. The other displays simply shows the placeholder.

/* The QEMU code relies on the assumption that it's always run in

* operations that produce different results depending on the
* locale, such as printf's formatting of decimal numbers, and
* possibly others.
*
* Since GTK+ calls setlocale() by default -importing the locale
* settings from the environment- we must prevent it from doing so
* using gtk_disable_setlocale().
*
* QEMU's GTK+ UI, however, _does_ have translations for some of
* the menu items. As a trade-off between a functionally correct
* QEMU and a fully internationalized UI we support importing
* LC_MESSAGES from the environment (see the setlocale() call
* earlier in this file). This allows us to display translated
* messages leaving everything else untouched.
