Hi all,
this patch fixes the curses interface: when we switch from one console
to another we need to change the displaystate width and height even
though in the curses case the backing buffer remains of the same size.
I am also putting back the call to text_console_resize in
text_console_invalidate so that resizeable text consoles can be properly
handled.

This patch changes the DisplayState interface adding support for
multiple frontends at the same time (sdl and vnc) and implements most
of the benefit of the shared_buf patch without the added complexity.
Currently DisplayState is managed by sdl (or vnc) and sdl (or vnc) is
also responsible for allocating the data and setting the depth.
Vga.c (or another backend) will do any necessary conversion.
The idea is to change it so that is vga.c (or another backend) together
with console.c that fully manage the DisplayState interface allocating
data and setting the depth (either 16 or 32 bit, if the guest uses a
different resolution or is in text mode, vga.c (or another backend) is
in charge of doing the conversion seamlessly).
The other idea is that DisplayState supports *multiple* frontends
like sdl and vnc; each of them can register some callbacks to be called
when a display event occurs.
The interesting changes are:
- the new structures and related functions in console.h and console.c
in particular the following functions are very helpful to manage a
DisplaySurface:
qemu_create_displaysurface
qemu_resize_displaysurface
qemu_create_displaysurface_from
qemu_free_displaysurface
- console_select and qemu_console_resize in console.c
this two functions manage multiple consoles on a single host display
- moving code around in hw/vga.c
as for the shared_buf patch this is necessary to be able to handle a dynamic
DisplaySurface bpp
- changes to vga_draw_graphic in hw/vga.c
this is the place where the DisplaySurface buffer is shared with the
videoram, when possible;
Compared to the last version the only changes are:
- do not remove support to dpy_copy in cirrus_vga
- change the name of the displaysurface handling functions

This partially reverts r4812 to fix an issue highlighted by Ryan Harper
with all vc's being fixed size which prevented backends with resizable
window (curses) from displaying okay.

This patch makes qemu handle signals better. It sets the request_shutdown
flag, making the main_loop exit and qemu taking the usual exit route, with
atexit handlers being called and so on, instead of qemu just being killed
by the signal.
To avoid calling vm_start() from the signal handler main_loop() got an
additional check so qemu_system_shutdown_request() works even when the
vm is in stopped state.
