We want to introduce a new version of qemu_open() that uses an Error
object for reporting problems and make this it the preferred interface.
Rename the existing method to release the namespace for the new impl.

The new property allows to specify usb host device name. Uses standard
qemu_open(), so both file system path (/dev/bus/usb/$bus/$dev on linux)
and file descriptor passing can be used.
Requires libusb 1.0.23 or newer. The hostdevice property is only
present in case qemu is compiled against a new enough library version,
so the presence of the property can be used for feature detection.

Devices may have component devices and buses.
Device realization may fail. Realization is recursive: a device's
realize() method realizes its components, and device_set_realized()
realizes its buses (which should in turn realize the devices on that
bus, except bus_set_realized() doesn't implement that, yet).
When realization of a component or bus fails, we need to roll back:
unrealize everything we realized so far. If any of these unrealizes
failed, the device would be left in an inconsistent state. Must not
happen.
device_set_realized() lets it happen: it ignores errors in the roll
back code starting at label child_realize_fail.
Since realization is recursive, unrealization must be recursive, too.
But how could a partly failed unrealize be rolled back? We'd have to
re-realize, which can fail. This design is fundamentally broken.
device_set_realized() does not roll back at all. Instead, it keeps
unrealizing, ignoring further errors.
It can screw up even for a device with no buses: if the lone
dc->unrealize() fails, it still unregisters vmstate, and calls
listeners' unrealize() callback.
bus_set_realized() does not roll back either. Instead, it stops
unrealizing.
Fortunately, no unrealize method can fail, as we'll see below.
To fix the design error, drop parameter @errp from all the unrealize
methods.
Any unrealize method that uses @errp now needs an update. This leads
us to unrealize() methods that can fail. Merely passing it to another
unrealize method cannot cause failure, though. Here are the ones that
do other things with @errp:
* virtio_serial_device_unrealize()
Fails when qbus_set_hotplug_handler() fails, but still does all the
other work. On failure, the device would stay realized with its
resources completely gone. Oops. Can't happen, because
qbus_set_hotplug_handler() can't actually fail here. Pass
&error_abort to qbus_set_hotplug_handler() instead.
* hw/ppc/spapr_drc.c's unrealize()
Fails when object_property_del() fails, but all the other work is
already done. On failure, the device would stay realized with its
vmstate registration gone. Oops. Can't happen, because
object_property_del() can't actually fail here. Pass &error_abort
to object_property_del() instead.
* spapr_phb_unrealize()
Fails and bails out when remove_drcs() fails, but other work is
already done. On failure, the device would stay realized with some
of its resources gone. Oops. remove_drcs() fails only when
chassis_from_bus()'s object_property_get_uint() fails, and it can't
here. Pass &error_abort to remove_drcs() instead.
Therefore, no unrealize method can fail before this patch.
device_set_realized()'s recursive unrealization via bus uses
object_property_set_bool(). Can't drop @errp there, so pass
&error_abort.
We similarly unrealize with object_property_set_bool() elsewhere,
always ignoring errors. Pass &error_abort instead.
Several unrealize methods no longer handle errors from other unrealize
methods: virtio_9p_device_unrealize(),
virtio_input_device_unrealize(), scsi_qdev_unrealize(), ...
Much of the deleted error handling looks wrong anyway.
One unrealize methods no longer ignore such errors:
usb_ehci_pci_exit().
Several realize methods no longer ignore errors when rolling back:
v9fs_device_realize_common(), pci_qdev_unrealize(),
spapr_phb_realize(), usb_qdev_realize(), vfio_ccw_realize(),
virtio_device_realize().

* It pulls in more than a dozen additional headers.

sysemu/runstate.h.
Touching sysemu/sysemu.h now recompiles some 850 objects. qemu/uuid.h

With certain USB devices passed through via usb-host, a guest attempting to
reset a usb-host device can trigger a reset loop that renders the USB device
unusable. In my use case, the device was an iPhone XR that was passed through to
a Mac OS X Mojave guest. Upon connecting the device, the following happens:
1) Guest recognizes new device, sends reset to emulated USB host
2) QEMU's USB host sends reset to host kernel
3) Host kernel resets device
4) After reset, host kernel determines that some part of the device descriptor
has changed ("device firmware changed" in dmesg), so host kernel decides to
re-enumerate the device.
5) Re-enumeration causes QEMU to disconnect and reconnect the device in the
guest.
6) goto 1)
Here's from the host kernel (note the "device firmware changed" lines")

The result of this is that the device remains permanently unusable in the guest.
The same problem has been previously reported for an iPad:
https://stackoverflow.com/questions/52617634/how-do-i-get-qemu-usb-passthrough-to-work-for-ipad-iphone
This problem can be elegantly solved by interrupting step 2) above. Instead of
passing through the reset, QEMU simply ignores it. To allow this to be
configured on a per-device level, a new parameter "no_guest_reset" is
introduced for the usb-host device. I can confirm that the configuration
described above (iPhone XS + Mojave guest) works flawlessly with
no_guest_reset=True specified.
Working command line for my scenario:
device_add usb-host,vendorid=0x05ac,productid=0x12a8,no_guest_reset=True,id=iphone

usb-host emulates a device unplug after live migration, because the
device state is unknown and unplug/replug makes sure the guest
re-initializes the device into a working state. This can't be done in
post-load though, so post-load just schedules a bottom half which
executes after vmload is complete.
It can happen that the device autoscan timer hits the race window
between scheduling and running the bottom half, which in turn can
triggers an assert().
Fix that issue by just ignoring the usb_host_open() call in case the
bottom half didn't execute yet.

Some USB devices have sparse interface numbering which is not able to be
passthroughed.
For example, the Sierra Wireless MC7455/MC7430:
# lsusb -D /dev/bus/usb/003/003 | egrep '1199|9071|bNumInterfaces|bInterfaceNumber'
Device: ID 1199:9071 Sierra Wireless, Inc.
idVendor 0x1199 Sierra Wireless, Inc.
idProduct 0x9071
bNumInterfaces 5
bInterfaceNumber 0
bInterfaceNumber 2
bInterfaceNumber 3
bInterfaceNumber 8
bInterfaceNumber 10
In this case, the interface numbers are 0, 2, 3, 8, 10 and not the
0, 1, 2, 3, 4 that QEMU tries to claim.
This change allows sparse USB interface numbering.
Instead of only claiming the interfaces in the range reported by the USB
device through bNumInterfaces, QEMU attempts to claim all possible
interfaces.

libusbx doesn't exist any more, the fork got merged back to libusb. So
stop using LIBUSBX_API_VERSION and use LIBUSB_API_VERSION instead. For
backward compatibility alias LIBUSB_API_VERSION to LIBUSBX_API_VERSION
in case we figure LIBUSB_API_VERSION isn't defined.

Curiously, unrealize() is not being used, but it seems more
appropriate than handle_destroy() together with realize(). It is more
ubiquitous destroy name in qemu code base and may throw errors.

When passing through an USB storage device to a pseries guest, it
is currently not possible to automatically boot from the device
if the "bootindex" property has been specified, too (e.g. when using
"-device nec-usb-xhci -device usb-host,hostbus=1,hostaddr=2,bootindex=0"
at the command line). The problem is that QEMU builds a device tree path
like "/pci@800000020000000/usb@0/usb-host@1" and passes it to SLOF
in the /chosen/qemu,boot-list property. SLOF, however, probes the
USB device, recognizes that it is a storage device and thus changes
its name to "storage", and additionally adds a child node for the
SCSI LUN, so the correct boot path in SLOF is something like
"/pci@800000020000000/usb@0/storage@1/disk@101000000000000" instead.
So when we detect an USB mass storage device with SCSI interface,
we've got to adjust the firmware boot-device path properly that
SLOF can automatically boot from the device.

The companion descriptor is present on all usb3 devices, not only
those with streams support. We need to check attributes to see
whenever the device uses streams or not.

This patch changes usb-host behavior in case we hostbus= and hostaddr=
properties are used to identify the usb device in question. Instead of
adding the device to the hotplug watchlist we try to open directly using
the given bus number and device address.
Putting a device specified by hostaddr to the hotplug watchlist isn't
a great idea as the address isn't a fixed property. It changes every
time the device is plugged in. So considering this case as "use the
device at bus:addr _now_" is more sane. Also usb-host will throw errors
in case it can't initialize the host device.
Note: For devices on the hotplug watchlist (hostport or vendorid or
productid specified) qemu continues to ignore errors and keeps
monitoring the usb bus to see if the device eventually shows up.

Commit 57cb38b included qapi/error.h into qemu/osdep.h to get the
Error typedef. Since then, we've moved to include qemu/osdep.h
everywhere. Its file comment explains: "To avoid getting into
possible circular include dependencies, this file should not include
any other QEMU headers, with the exceptions of config-host.h,
compiler.h, os-posix.h and os-win32.h, all of which are doing a
similar job to this file and are under similar constraints."
qapi/error.h doesn't do a similar job, and it doesn't adhere to
similar constraints: it includes qapi-types.h. That's in excess of
100KiB of crap most .c files don't actually need.
Add the typedef to qemu/typedefs.h, and include that instead of
qapi/error.h. Include qapi/error.h in .c files that need it and don't
get it now. Include qapi-types.h in qom/object.h for uint16List.
Update scripts/clean-includes accordingly. Update it further to match
reality: replace config.h by config-target.h, add sysemu/os-posix.h,
sysemu/os-win32.h. Update the list of includes in the qemu/osdep.h
comment quoted above similarly.
This reduces the number of objects depending on qapi/error.h from "all
of them" to less than a third. Unfortunately, the number depending on
qapi-types.h shrinks only a little. More work is needed for that one.

usb->speed is the usb speed the device is actually running on in the
qemu emulation (i.e. from the guests point of view). So when plugging
usb3 devices into ehci hostadapter this is HIGH not SUPER.
To figure whenever the host talks to the device with superspeed we
have to check speedmask instead and see whenever the superspeed bit
is set there.

Many source files have doubled words (eg "the the", "to to",
and so on). Most of these can simply be removed, but a couple
were actual mis-spellings (eg "to to" instead of "to do").
There was even one triple word score "to to to" :-)

Some are called do_info_SUBCOMMAND() (old ones, usually), some
hmp_info_SUBCOMMAND(), some SUBCOMMAND_info(), sometimes SUBCOMMAND
pointlessly differs in spelling.
Normalize to hmp_info_SUBCOMMAND(), where SUBCOMMAND is exactly the
subcommand name with '-' replaced by '_'.
Exceptions:
* sun4m_irq_info(), sun4m_pic_info() renamed to sun4m_hmp_info_irq(),
sun4m_hmp_info_pic().
* lm32_irq_info(), lm32_pic_info() renamed to lm32_hmp_info_irq(),
