Fix display breakage when resizing the screen (v2) (Avi Kivity)

When the vga resolution changes, a new display surface is not allocated
immediately; instead that is deferred until the next update. However,
if we're running without a display client attached, that won't happen...

fix screendump (Stefano Stabellini)

this patch fixes the screendump functionality that was recently broken;
it must be applied after PATCH 5, 6 and 7 of the original displaystate
change patch series.
In fact the other patches make much easier to solve the screendump...

graphical_console_init change (Stefano Stabellini)

Patch 5/7

This patch changes the graphical_console_init function to return an
allocated DisplayState instead of a QEMUConsole.

This patch contains just the graphical_console_init change and few other
modifications mainly in console.c and vl.c....

DisplayState interface change (Stefano Stabellini)

This patch changes the DisplayState interface adding support for

Add cirrus reset handler

The vga reset handler overwrites some cirrus registers, causing reboots
to corrupt cirrus state to the point that guests can only bring up 640x480
resolutions.

Fix by adding a dedicated cirrus reset handler (which calls the common vga...

vga optimization (Glauber Costa)

Hypervisors like KVM perform badly while doing mmio on
a loop, because it'll generate an exit on each access.
This is the case with VGA, which results in very bad
performance.

In this patch, we map the linear frame buffer as RAM,...
