66a08cbe6a uhci: Verify queue has not been changed by guest
According to the spec a guest can unlink a qh, and then as soon as frindex
has changed by 1 since the unlink, assume it is idle and re-use it. However
for various reasons, we cannot simply consider a qh as unlinked if we've not
seen it for 1 frame. This means that it is possible for a guest to re-use /
restart the queue while we still see its old state. This patch adds a safety
check for this, and "early" retires queues when they were changed by the guest.

747ff60263 block: add live block commit functionality
This adds the live commit coroutine.  This iteration focuses on the
commit only below the active layer, and not the active layer itself.

The behaviour is similar to block streaming; the sectors are walked
through, and anything that exists above 'base' is committed back down
into base.  At the end, intermediate images are deleted, and the
chain stitched together.  Images are restored to their original open
flags upon completion.

a639ab0482 hw/qxl: support client monitor configuration via device
Until now we used only the agent to change the monitor count and each
monitor resolution. This patch introduces the qemu part of using the
device as the mediator instead of the agent via virtio-serial.

Spice (>=0.11.5) calls the new QXLInterface::client_monitors_config,
which returns wether the interrupt is enabled, and if so and given a non
NULL monitors config will
generate an interrupt QXL_INTERRUPT_CLIENT_MONITORS_CONFIG with crc
checksum for the guest to verify a second call hasn't interfered.

The maximal number of monitors is limited on the QXLRom to 64.

Also register different memory regions for capabilities,

regs.  Ditch a bunch of sanity checks because the memory
core will do this for us now.

Offloading the byte, word and dword access handling to the
memory core also has the side effect of fixing ehci register
access on bigendian hosts.

d5a15814b4 xhci: drop buffering
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.

0ee2c058a3 pseries: Add PCI MSI/MSI-X support
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.

0f58f68b58 usb: add usb attached scsi emulation
$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.

afeecec2e8 Add rate limiting of RTC_CHANGE, BALLOON_CHANGE & WATCHDOG events
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
