A device of USB video class usually uses larger desc structure, so
use larger buffer to avoid failure. (dev-video.c is ready)
This is an unlikely code path:
1, during guest startup, guest tries to probe device.
2, run 'lsusb' command in guest(or other similar commands).

The function scsi_bus_new() creates a new SCSI bus; callers can
either pass in a name argument to specify the name of the new bus, or
they can pass in NULL to allow the bus to be given an automatically
generated unique name. Almost all callers want to use the
autogenerated name; the only exception is the virtio-scsi device.
Taking a name argument that should almost always be NULL is an
easy-to-misuse API design -- it encourages callers to think perhaps
they should pass in some standard name like "scsi" or "scsi-bus". We
don't do this anywhere for SCSI, but we do (incorrectly) do it for
other bus types such as i2c.
The function name also implies that it will return a newly allocated
object, when it in fact does in-place allocation. We more commonly
name such functions foo_init(), with foo_new() being the
allocate-and-return variant.
Replace all the scsi_bus_new() callsites with either:
* scsi_bus_init() for the usual case where the caller wants
an autogenerated bus name
* scsi_bus_init_named() for the rare case where the caller
needs to specify the bus name
and document that for the _named() version it's then the caller's
responsibility to think about uniqueness of bus names.

Per xHCI spec v1.2 chapter 4.17.5 page 296:
If MSI or MSI-X interrupts are enabled, Interrupt Pending (IP)
shall be cleared automatically when the PCI dword write generated
by the interrupt assertion is complete.
Currently QEMU does not clear the IP flag in the MSI / MSI-X mode.
This causes subsequent spurious interrupt to be delivered to guests.
To solve this, we change the xhci intr_raise() hook routine to have
a bool return value that is passed to its caller (the xhci core),
with true indicating that IP should be self-cleared.

"-usbdevice braille" is still a very useful shortcut for some people.
Thus we never remove this option. Since it's not such a big burden to
keep it around, and it's also convenient in the sense that you don't
have to worry to enable a host controller explicitly with this option,
we should remove it from he deprecation list again.
However, there is one exception: "-usbdevice audio" should go away, since
audio devices without "audiodev=..." parameter are also on the deprecation
list and you cannot use "-usbdevice audio" with "audiodev".

In order to keep track of the alternate setting that should be used for
a given interface, the USBDevice struct keeps an array of alternate
setting values, which is indexed by the interface number. In
usb_host_set_interface, when this array is updated, usb_host_ep_update
is called as a result. However, when usb_host_ep_update accesses the
active libusb_config_descriptor, it indexes udev->altsetting with the
loop variable, rather than the interface number.
With the simple trace backend enable, this behavior can be seen:
[...]
usb_xhci_xfer_start 0.440 pid=1215 xfer=0x5596a4b85930 slotid=0x1 epid=0x1 streamid=0x0
usb_packet_state_change 1.703 pid=1215 bus=0x1 port=b'1' ep=0x0 p=0x5596a4b85938 o=b'undef' n=b'setup'
usb_host_req_control 2.269 pid=1215 bus=0x1 addr=0x5 p=0x5596a4b85938 req=0x10b value=0x1 index=0xd
usb_host_set_interface 0.449 pid=1215 bus=0x1 addr=0x5 interface=0xd alt=0x1
usb_host_parse_config 2542.648 pid=1215 bus=0x1 addr=0x5 value=0x2 active=0x1
usb_host_parse_interface 1.804 pid=1215 bus=0x1 addr=0x5 num=0xc alt=0x0 active=0x1
usb_host_parse_endpoint 2.012 pid=1215 bus=0x1 addr=0x5 ep=0x2 dir=b'in' type=b'int' active=0x1
usb_host_parse_interface 1.598 pid=1215 bus=0x1 addr=0x5 num=0xd alt=0x0 active=0x1
usb_host_req_emulated 3.593 pid=1215 bus=0x1 addr=0x5 p=0x5596a4b85938 status=0x0
usb_packet_state_change 2.550 pid=1215 bus=0x1 port=b'1' ep=0x0 p=0x5596a4b85938 o=b'setup' n=b'complete'
usb_xhci_xfer_success 4.298 pid=1215 xfer=0x5596a4b85930 bytes=0x0
[...]
In particular, it is seen that although usb_host_set_interface sets the
alternate setting of interface 0xd to 0x1, usb_host_ep_update uses 0x0
as the alternate setting due to using the incorrect index to
udev->altsetting.
Fix this problem by getting the interface number from the active
libusb_config_descriptor, and then using that as the index to
udev->altsetting.

Currently, blk_is_read_only() tells whether a given BlockBackend can
only be used in read-only mode because its root node is read-only. Some
callers actually try to answer a slightly different question: Is the
BlockBackend configured to be writable, by taking write permissions on
the root node?
This can differ, for example, for CD-ROM devices which don't take write
permissions, but may be backed by a writable image file. scsi-cd allows
write requests to the drive if blk_is_read_only() returns false.
However, the write request will immediately run into an assertion
failure because the write permission is missing.
This patch introduces separate functions for both questions.
blk_supports_write_perm() answers the question whether the block
node/image file can support writable devices, whereas blk_is_writable()
tells whether the BlockBackend is currently configured to be writable.
All calls of blk_is_read_only() are converted to one of the two new
functions.

Commit 8118f0950f "migration: Append JSON description of migration
stream" needs a JSON writer. The existing qobject_to_json() wasn't a
good fit, because it requires building a QObject to convert. Instead,
migration got its very own JSON writer, in commit 190c882ce2 "QJSON:
Add JSON writer". It tacitly limits numbers to int64_t, and strings
contents to characters that don't need escaping, unlike
qobject_to_json().
The previous commit factored the JSON writer out of qobject_to_json().
Replace migration's JSON writer by it.

Remove the "default y" for USB_XHCI_SYSBUS because
sysbus devices are not user creatable; boards that use them will
specify them manually with "imply" or "select" clauses.
It would be nice to keep the ability to remove PCIe and USB from microvm,
since thos can be disabled on the command line and therefore should not
be included if QEMU is configured --without-default-devices. However
it's too late for 5.2 to figure out a place for the DSDT creation code.

Some operating systems will generate a new device ID when a USB device is unplugged
and then replugged into the USB. If this is done whilst switching between multiple
applications over a virtual serial port, the change of device ID requires going
back into the OS/application to locate the new device accordingly.
Add a new always-plugged property that if specified will ensure that the device
always remains attached to the USB regardless of the state of the backend
