usb_msd_copy_data() may cause a recursive call to
usb_msd_command_complete() which in turn may complete
the packet, setting s->packet to NULL in case it does.
Recheck s->packet before calling usb_packet_complete()
to fix the double call.

Make the linux usb host passthrough code use the usb_generic_handle_packet()
function, rather then the curent DYI code. This removes 200 lines of almost
identical code.

Descriptor
This is used for some devices that have multiple interfaces that form a logic
device. An example is Video Class, which has a Control interface and a
Streaming interface. There can be additional interfaces on the same (physical)
devices (e.g. a microphone), and Interface Association Descriptor handles this
case.

the s390 memory detection has a 16bit field that specifies the amount of
increments. This patch adopts the memory size to always fit into that
scheme. This also fixes virtio detection for these guests, since the
descriptor page is located after the main memory.

The s390x virtio bus keeps management information on virtio after the top
of the guest's RAM. We need to be able to tell the guest the size of its
RAM (without virtio stuff), but also be able to trap when the guest accesses
RAM outside of its scope (including virtio stuff).
So we need a variable telling us the size of the virtio stuff, so we can
calculate the highest available RAM address from that.
While at it, also increase the maximum number of virtio pages, so we play
along well with more recent kernels that spawn a ridiculous number of virtio
console adapters.

AHCI provides two ways of reading/writing data:
1) NCQ
2) ATA commands with the LBA in the command FIS
In the second code path, we didn't handle any LBAs that were bigger than
16 bits, so whenever a guest that used high LBA numbers wanted to access
data, the LBA got truncated down to 16 bits, giving the guest garbage.
This patch adds support for LBAs higher than 16 bits. I've tested that it
works just fine with SeaBIOS and Linux guests. This patch also unbreaks
the often reported grub errors people have seen with AHCI.

This patch makes qemu ignore unplug requests from the guest for pci
devices which are tagged as non-hotpluggable. Trouble spot is the
piix4 chipset with the ISA bridge. Requests to unplug that one will
make it go away together with all ISA bus devices, which are not
prepared to be unplugged and thus don't cleanup, leaving active
qemu timers behind in free'ed memory.

DriveInfo is closely tied to -drive, and like -drive, it mixes
information about host and guest part of the block device. Unlike
DriveInfo, BlockDriverState should be about the host part only.
One of the remaining guest bits there is the "type hint". -drive
option media sets it, and qdevs "ide-drive", "scsi-disk" and non-qdev
IF_XEN devices check it to pick HD vs. CD.
Communicate -drive option media via new DriveInfo member media_cd
instead.

A "scsi-disk" is either a hard disk or a CD-ROM, depending on the
associated BlockDriverState's type hint. Unclean; disk vs. CD belongs
to the guest part, not the host part.
Have separate qdevs "scsi-hd" and "scsi-cd" to model disk vs. CD in
the guest part.
Keep scsi-disk for backward compatibility.
Don't copy scsi-disk property removable to scsi-cd. It's not used and
always zero(!) there.

"ide-disk" would perhaps be a nicer name than "ide-hd", but there's
already "scsi-disk", which is like "ide-drive", and will be likewise
split in the next commit. {ide,scsi}-{hd,cd} is the best consistent
set of names I could find within the backward compatibility
straightjacket.

The pSeries machine uses two tables to look up guest hcalls for emulation.
One of these is exactly one entry too small to hold all the hcalls it needs
to, leading to memory corruption.
This patch fixes the bug, and while we're at it, make both tables 'static'
since they're never used from other modules.

Currently the qemu pseries machine numbers its virtual serial devices
from 0. However, existing pSeries machines running pHyp number them from
0x30000000.
In theory these indices are arbitrary, since everything necessary for the
kernel to find them is advertised in the device tree. However the debian
installer, at least, incorrectly looks for a device named vty@30... to
determine whether to use the hypervisor console.
Therefore this patch moves the numbers we use to match the existing pHyp
practice, in order to workaround broken userspace apps of this type.

Currently, the qemu emulated pseries machine puts
"qemu,emulated-pSeries-LPAR" in the device tree's root level 'model'

this problem, making the property more closely resemble the pattern of

Prototype without "inline" keyword breaks the build with some gcc
