The vga screen dump function updates last_width and last_height,
but does not change the DisplaySurface that these variables describe.
A consequent vga_draw_graphic() will therefore fail to resize the
surface and crash.
Fix by invalidating the display state after a screen dump, forcing
vga_draw_graphic() to reallocate the DisplaySurface.

This is mainly for consistency, since we don't want
anything outside of savevm setting it explicitly. There
are current no users of that in qemu tree, but there
are potential candidates on kvm-userspace. And avi
is a nice guy, let's be nice with him.

This fixes:
- The error message to show the actual if= argument value. It was showing
the filename instead, because 'buf' is reaused on the filename parsing.
- A bug that makes a block device to be created even when an unsupported if= arg
is passed to pci_add.

There may be cases where the guest does not want the avail queue
interrupt, even when it's empty. For the virtio-net case, the
guest may use a different buffering scheme or decide polling for
used buffers is more efficient. This can be accomplished by simply
checking for whether the guest has acknowledged the existing notify
on empty flag.

The RXDMT0 interrupt is supposed to fire when the number of free
RX descriptors drops to some fraction of the total descriptors.
However in practice, it seems like we're adding this interrupt
cause on every RX. Fix the logic to treat (tail - head) as the
number of free entries rather than the number of used entries.

Reading the passwords for encrypted hard disks during early startup is
broken (I guess for quiet a while now):
- No monitor terminal is ready for input at this point
- Forcing all mux'ed terminals into monitor mode can confuse other
users of that channels
To overcome these issues and to lay the ground for a clean decoupling of
monitor terminals, this patch changes the initial password inquiry as
follows:
- Prevent autostart if there is some encrypted disk
- Once the user tries to resume the VM, prompt for all missing
passwords
- Only resume if all passwords were accepted

After doing a video to video copy, cirrus_do_copy() in cirrus_vga.c does a
conditional call to cirrus_invalidate_region() with an "if (!notify)" test.
However at this point the blt has already been done so it seems like this call
should be made unconditionally. The patch below fixes some display update

cirrus_do_copy() in hw/cirrus_vga.c seems to make some incorrect assumptions
about video memory layout. It tries to convert addresses to coordinates
assuming that one row of data is (width * depth) bytes long. The correct way
seems to be to use the pitch fields in the CirrusVGAState structure instead.
Without this patch, I get lots of screen corruption when I try to drag a window
under X as it's passing the wrong coordinates to the display surface for the
copy. With this patch I can drag a window with no screen corruption.

Add monitor command to hot-add PCI devices (nic and storage).
Syntax is:

It returns the domain, bus and slot for the newly added device on success.
It is possible to attach a disk to a device after PCI initialization via
the drive_add command. If so, a manual scan of the SCSI bus on the guest
is necessary.
