Floppies can be simple or double-sided. However, current code
was only taking the common case into account (ie 2 sides).
This repairs single-sided floppies, which where totally broken
before this patch : for track > 0, wrong sector number was
calculated, and data was read/written at wrong place on
underlying device.
Fortunately, only some 360 kB floppies are single-sided, so
this bug was probably not seen much.

This patch adds an 64bit pci bar for vram. It is turned off by default.
It can be enabled by setting the size of the 64bit bar to be larger than
the 32bit bar. Both 32bit and 64bit bar refer to the same memory. Only
the first part of the memory is available via 32bit bar.
The intention is to allow large vram sizes for 64bit guests, by allowing
the vram bar being mapped above 4G, so we don't have to squeeze it into
the pci I/O window below 4G.
With vram_size_mb=16 and vram64_size_mb=256 it looks like this:
00:02.0 VGA compatible controller: Red Hat, Inc. Device 0100 (rev 02) (prog-if 00 [VGA controller])

Physical Slot: 2

When creating an USB device the old way, there is no way to specify the
target bus. Thus the warning issued by usb_create makes no sense and
rather confuses our users.
Resolve this by passing a bus reference to the usbdevice_init handler
and letting those handlers forward it to usb_create.

Before this patch the ehci code was not checking for any other errors other
then USB_RET_NAK. This causes 2 problems:
1) Other errors are not reported to the guest.
2) When transactions with the ITD_XACT_IOC bit set completing with another
error would not result in USBSTS_INT getting set.
I hit this problem when unplugging devices while iso data was streaming from
the device to the guest. When this happens it takes a while for the guest to
process the unplugging and remove ISO transactions from the ehci schedule, in
the mean time these transactions would complete with a result of USB_RET_NODEV,
which was not handled. This lead to the Linux guest's usb subsystem "hanging",
that is it would no longer see new usb devices getting plugged in and running
for example lsusb would lead to a stuck (D state) lsusb process. This patch
fixes this.

Check for dev->config being NULL in two places:
USB_REQ_GET_CONFIGURATION and USB_REQ_GET_STATUS.
The behavior of USB_REQ_GET_STATUS is unspecified in the Default state,
that corresponds to dev->config being NULL (it defaults to NULL and is
reset whenever a SET_CONFIGURATION with value 0, or attachment). I
implemented it to correspond with the state before
ed5a83ddd8, the commit moving SET_STATUS
to usb-desc; if dev->config is not set we return whatever is in the
first configuration.
The behavior of USB_REQ_GET_CONFIGURATION is also undefined before any
SET_CONFIGURATION, but here we just return 0 (same as specified for the
Address state).
A win7 guest failed to initialize the device before this patch,
segfaulting when GET_STATUS was called with dev->config == NULL. With
this patch the passthrough device still doesn't work but the failure is
unrelated.

RHBZ# 747011
Removes the last user of QXL_SYNC when using update drivers that use the
_ASYNC io ports.
The last user is qxl_render_update, it is called both by qxl_hw_update
which is the vga_hw_update_ptr passed to graphic_console_init, and by
qxl_hw_screen_dump.
At the same time the QXLRect area being passed to the red_worker thread
is passed as a copy, as part of the QXLCookie.
The implementation uses interface_update_area_complete with a bh to make
sure dpy_update and qxl_flip are called from the io thread, otherwise
the vga->ds->surface.data can change under our feet.
With this patch sdl+spice works fine. But spice by itself doesn't
produce the expected screendumps unless repeated a few times, due to
ppm_save being called before update_area (rendering done in spice server
thread) having a chance to complete. Fixed by next patch, but see commit
message for problem introduced by it.
