Device ivshmem property use64=0 is designed to make the device
expose a 32 bit shared memory BAR instead of 64 bit one. The
default is a 64 bit BAR, except pc-1.2 and older retain a 32 bit
BAR. A 32 bit BAR can support only up to 1 GiB of shared memory.
This worked as designed until commit 5400c02 accidentally flipped
its sense: since then, we misinterpret use64=0 as use64=1 and vice
versa. Worse, the default got flipped as well. Devices
ivshmem-plain and ivshmem-doorbell are not affected.
Fix by restoring the test of IVShmemState member not_legacy_32bit
that got messed up in commit 5400c02. Also update its
initialization for devices ivhsmem-plain and ivshmem-doorbell.
Without that, they'd regress to 32 bit BARs.

Dataplane has been omitting forever the step of setting ISR when
an interrupt is raised. This caused little breakage, because the
specification actually says that ISR may not be updated in MSI mode.
Some versions of the Windows drivers however didn't clear MSI mode
correctly, and proceeded using polling mode (using ISR, not the used
ring index!) for crashdump and hibernation. If it were just crashdump
and hibernation it would not be a big deal, but recent releases of
Windows do not really shut down, but rather log out and hibernate to
make the next startup faster. Hence, this manifested as a more serious
hang during shutdown with e.g. Windows 8.1 and virtio-win 1.8.0 RPMs.
Newer versions fixed this, while older versions do not use MSI at all.
The failure has always been there for virtio dataplane, but it became
visible after commits 9ffe337 ("virtio-blk: always use dataplane path
if ioeventfd is active", 2016-10-30) and ad07cd6 ("virtio-scsi: always
use dataplane path if ioeventfd is active", 2016-10-30) made virtio-blk
and virtio-scsi always use the dataplane code under KVM. The good news
therefore is that it was not a bug in the patches---they were doing
exactly what they were meant for, i.e. shake out remaining dataplane bugs.
The fix is not hard, so it's worth arranging for the broken drivers.
The virtio_should_notify+event_notifier_set pair that is common to
virtio-blk and virtio-scsi dataplane is replaced with a new public
function virtio_notify_irqfd that also sets ISR. The irqfd emulation
code now need not set ISR anymore, so virtio_irq is removed.

Following the recent refactoring of virtio notifiers [1], more specifically
the patch ed08a2a0b ("virtio: use virtio_bus_set_host_notifier to
start/stop ioeventfd") that uses virtio_bus_set_host_notifier [2]
by default, core virtio code requires 'ioeventfd_started' to be set
to true/false when the host notifiers are configured.
When vhost is stopped and started, however, there is a stop followed by
another start. Since ioeventfd_started was never set to true, the 'stop'
operation triggered by virtio_bus_set_host_notifier() will not result
in a call to virtio_pci_ioeventfd_assign(assign=false). This leaves
the memory regions with stale notifiers and results on the next start
triggering the following assertion:
kvm_mem_ioeventfd_add: error adding ioeventfd: File exists
Aborted
This patch reintroduces (hopefully in a cleaner way) the concept
that was present with ioeventfd_disabled before the refactoring.
When ioeventfd_grabbed>0, ioeventfd_started tracks whether ioeventfd
should be enabled or not, but ioeventfd is actually not started at
all until vhost releases the host notifiers.

We must check for new virtqueue buffers after re-enabling notifications.
This prevents the race condition where the guest added buffers just
after we stopped popping the virtqueue but before we re-enabled
notifications.
I think the virtio-crypto code was based on virtio-net but this crucial
detail was missed. virtio-net does not have the race condition because
it processes the virtqueue one more time after re-enabling
notifications.

The legacy vring layout is not used anymore as we use the separate
mappings even for legacy devices.
This patch simply removes it.
This also fixes a bug with virtio 1 devices when the vring descriptor table
is mapped at a higher address than the used vring because the following
function may return an insanely great value:
hwaddr virtio_queue_get_ring_size(VirtIODevice *vdev, int n)
{
return vdev->vq[n].vring.used - vdev->vq[n].vring.desc +
virtio_queue_get_used_size(vdev, n);
}
and the mapping fails.

With virtio 1, the vring layout is split in 3 separate regions of
contiguous memory for the descriptor table, the available ring and the
used ring, as opposed with legacy virtio which uses a single region.
In case of memory re-mapping, the code ensures it doesn't affect the
vring mapping. This is done in vhost_verify_ring_mappings() which assumes
the device is legacy.
This patch changes vhost_verify_ring_mappings() to check the mappings of
each part of the vring separately.
This works for legacy mappings as well.

virtio 1.0 spec says this is a legacy feature bit,
hide it from guests in modern mode.
Note: for cross-version migration compatibility,
we keep the bit set in host_features.
The result will be that a guest migrating cross-version
will see host features change under it.
As guests only seem to read it once, this should
not be an issue. Meanwhile, will work to fix guests to
ignore this bit in virtio1 mode, too.

using -usbdevice keyboard when accessed through vnc with a gtk-vnc based
client.
The reason for this is a mismatch between gtk-vnc and qemu in how these keys
should be mapped to XT keycodes.
On the original IBM XT these keys behaved differently than other keys.
Quoting from https://www.win.tue.nl/~aeb/linux/kbd/scancodes-1.html:
The keys PrtSc/SysRq and Pause/Break are special. The former produces
scancode e0 2a e0 37 when no modifier key is pressed simultaneously, e0 37
together with Shift or Ctrl, but 54 together with (left or right) Alt. (And
one gets the expected sequences upon release. But see below.) The latter
produces scancode sequence e1 1d 45 e1 9d c5 when pressed (without modifier)
and nothing at all upon release. However, together with (left or right)
Ctrl, one gets e0 46 e0 c6, and again nothing at release. It does not
repeat.
Gtk-vnc supports the 'QEMU Extended Key Event Message' RFB extension to send
raw XT keycodes directly to qemu, but the specification doesn't explicitly
specify how to map such long/complicated keycode sequences. From the spec
(https://github.com/rfbproto/rfbproto/blob/master/rfbproto.rst#qemu-extended-key-event-message)
The keycode is the XT keycode that produced the keysym. An XT keycode is an
XT make scancode sequence encoded to fit in a single U32 quantity. Single
byte XT scancodes with a byte value less than 0x7f are encoded as is.
2-byte XT scancodes whose first byte is 0xe0 and second byte is less than
0x7f are encoded with the high bit of the first byte set
hid.c currently expects the keycode sequence with shift/ctl for sysrq (e0 37
-> 0xb7 in RFB), whereas gtk-vnc uses the sequence with alt (0x54).
Likewise, hid.c expects the code without modifiers (e1 1d 45 -> 0xc5 in
RFB), whereas gtk-vnc sends the keycode sequence with ctrl for pause (e0 46
-> 0xc6 in RFB).
See keymaps.cvs in gtk-vnc for the mapping used:
https://git.gnome.org/browse/gtk-vnc/tree/src/keymaps.csv#n150
Now, it isn't obvious to me which sequence is really "right", but as the
0x54/0xc6 keycodes are currently unused in hid.c, supporting both seems like
the pragmatic solution to me. The USB HID keyboard boot protocol used by
hid.c doesn't have any other mapping applicable to these keys.
The other guest keyboard interfaces (ps/2, virtio, ..) are not affected,
because they handle these keys differently.

GDK_KEY_Delete is only defined with gtk version 2.22 and newer,
on older versions this key was called GDK_Delete instead.
Since this is the case for all GDK_KEY_* defines, change the
already existing preprocessor check there to test for version 2.22,
so we know that we can remove this code block in case we require
that version as a minimum one day.

In usbredir destroy dispatch function, it doesn't free the vm change
state handler once registered in usbredir_realize function. This will
lead a memory leak issue. This patch avoid this.
