qapi: Introduce blockdev-group-snapshot-sync command

This is a QAPI/QMP only command to take a snapshot of a group of
devices. This is similar to the blockdev-snapshot-sync command, except
blockdev-group-snapshot-sync accepts a list devices, filenames, and
formats.

It is attempted to keep the snapshot of the group atomic; if the
creation or open of any of the new snapshots fails, then all of
the new snapshots are abandoned, and the name of the snapshot image
that failed is returned.  The failure case should not interrupt
any operations.

Rather than use bdrv_close() along with a subsequent bdrv_open() to
perform the pivot, the original image is never closed and the new
image is placed 'in front' of the original image via manipulation
of the BlockDriverState fields.  Thus, once the new snapshot image
has been successfully created, there are no more failure points
before pivoting to the new snapshot.

This allows the group of disks to remain consistent with each other,
even across snapshot failures.

qxl: add optinal 64bit vram bar

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])
        Subsystem: Red Hat, Inc Device 1100
        Physical Slot: 2
        Flags: fast devsel, IRQ 10
        Memory at f8000000 (32-bit, non-prefetchable) [size=64M]
        Memory at fc000000 (32-bit, non-prefetchable) [size=16M]
        Memory at fd020000 (32-bit, non-prefetchable) [size=8K]
        I/O ports at c5a0 [size=32]
        Memory at ffe0000000 (64-bit, prefetchable) [size=256M]

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.
