aliguori 3023f3329d 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.
It was necessary to move the display frontends (e.g. sdl and vnc)
initialization after machine->init in vl.c.

This patch does *not* include any required changes to any device, these
changes come with the following patches.

Patch 6/7

This patch changes the QEMUMachine init functions not to take a
DisplayState as an argument because is not needed any more;

In few places the graphic hardware initialization function was called
only if DisplayState was not NULL, now they are always called.
Apart from these cases, the rest are all mechanical substitutions.

Patch 7/7

This patch updates the graphic device code to use the new
graphical_console_init function.

As for the previous patch, in few places graphical_console_init was called
only if DisplayState was not NULL, now it is always called.
Apart from these cases, the rest are all mechanical substitutions.
