This patch splits the xhci_xfer_data function into three.
The xhci_xfer_data function used to do does two things:
(1) copy transfer data between guest memory and a temporary buffer.
(2) report transfer results to the guest using events.
Now we three functions to handle this:
(1) xhci_xfer_map creates a scatter list for the transfer and
uses that (instead of the temporary buffer) to build a
USBPacket.
(2) xhci_xfer_unmap undoes the mapping.
(3) xhci_xfer_report sends out events.
The patch also fixes reporting of transaction errors which must be
reported unconditinally, not only in case the guest asks for it
using the ISP flag.

Revision bumped to 4 for new IO support, enabled for spice-server >=
0.11.1. New io enabled if revision is 4. Revision can be set to 4.
[ kraxel: 3 continues to be the default revision. Once we have a new
stable spice-server release and the qemu patches to enable
the new bits merged we'll go flip the switch and make rev4
the default ]
This io calls the corresponding new spice api
spice_qxl_monitors_config_async to let spice-server read a new guest set
monitors config and notify the client.
On migration reissue spice_qxl_monitors_config_async.

This patch implements MSI and MSI-X support for the pseries PCI host
bridge. To do this it adds:
* A "config_space_address to msi_table" map, since the MSI RTAS calls
take a PCI config space address as an identifier.
* A MSIX memory region to catch msi_notify()/msix_notiry() from
virtio-pci and pass them to the guest via qemu_irq_pulse().
* RTAS call "ibm,change-msi" which sets up MSI vectors for a
device. Note that this call may configure and return lesser number of
vectors than requested.
* RTAS call "ibm,query-interrupt-source-number" which translates MSI
vector to interrupt controller (XICS) IRQ number.

trace_megasas_dcmd_dump_frame() takes 9 arguments, which is
rather much. Plus the trace infrastructure doesn't support
it. As we can get the information via other means it's pointless
to have it in the driver, so rather use some proper trace
point here and remove the old one.

Best to use the same type, to avoid unwanted truncation or sign

BlockConf can't use plain int for cyls, heads and secs, because
integer properties require an exact width.

$subject says all. First cut.
It's a pure UAS (usb attached scsi) emulation, without BOT (bulk-only
transport) compatibility. If your guest can't handle it use usb-storage
instead.
The emulation works like any other scsi hba emulation (eps, lsi, virtio,
megasas, ...). It provides just the HBA where you can attach scsi
devices as you like using '-device'. A single scsi target with up to
256 luns is supported.
For now only usb 2.0 transport is supported. This will change in the
future though as I plan to use this as playground when codeing up &
testing usb 3.0 transport and streams support in the qemu usb core and
the xhci emulation.
No migration support yet. I'm planning to add usb 3.0 support first as
this probably requires saving additional state.
Special thanks go to Paolo for bringing the qemu scsi emulation into
shape, so this can be added nicely without having to touch a single line
of scsi code.

Allow certain event types to be rate limited to avoid flooding
monitor clients. The monitor_protocol_event() method is changed
such that instead of immediately emitting the event to Monitor
instances, it will call a new monitor_protocol_event_queue()
method.
This will check to see if the rate limit for the event has been
exceeded, and if so schedule a timer to wakeup at the end of the
rate limit period. If further events arrive before the timer fires,
the previously queued event will be discarded in favour of the new
event. The event will eventually be emitted when the timer fires.
This logic is applied to RTC_CHANGE, BALLOON_CHANGE & WATCHDOG
events, since the data associated with these events is stateless

This patch carries a complete rewrite of the usb descriptor parser.
Changes / improvements:
* We are using the USBDescriptor struct instead of hard-coded offsets
now to access descriptor data.
* (debug) printfs are all gone, tracepoints have been added instead.
* We don't try (and fail) to skip over unneeded descriptors. We parse
them all one by one. We keep track of which configuration, interface
and altsetting we are looking at and use this information to figure
which desciptors are in use and which we can ignore.
* On parse errors we clear all endpoint information, which will
disallow any communication with the device, except control endpoint
messages. This makes sure we don't end up with a silly device state
where half of the endpoints got enabled and the other half was left
disabled.
* Some sanity checks have been added.
The new parser is more robust and also leaves complete device
information in the trace log if you enable the ush_host_parse_*
tracepoints.
