The Spice protocol uses cursor position on hotspot: the client is
applying hotspot offset when drawing the cursor.

Denis Kirjanov is busy getting spice run on ppc64 and trapped into this
one. Spice wire format is little endian, so we have to explicitly say
we want little endian when letting pixman convert the data for us.

Live migration with spice works like this today:
(1) client_migrate_info monitor cmd
(2) spice server notifies client, client connects to target host.
(3) qemu waits until spice client connect is finished.
(4) send over vmstate (i.e. main part of live migration).
(5) spice handover to target host.
(3) is implemented by making client_migrate_info a async monitor
command. This is the only async monitor command we have.
The original reason to implement this dance was that qemu did not accept
new tcp connections while the incoming migration was running, so (2) and
(4) could not be done in parallel. That issue was fixed long ago though.
Qemu version 1.3.0 (released Dec 2012) and newer happily accept tcp
connects while the incoming migration runs.
Time to drop step (3). This patch does exactly that, by making the
monitor command synchronous and removing the code needed to handle the
async monitor command in ui/spice-core.c

GTK2 sends the accel key to the guest when switching to the graphic
console via that shortcut. Resolve this by ignoring any keys until the
next key-release event. However, do not ignore keys when switching via
the menu or when on GTK3.

At least on GTK2, the VTE terminal has to be specified as target of
gtk_widget_grab_focus. Otherwise, switching from one VTE terminal to
another causes the focus to get lost.

Pretending that QMP doesn't understand a command merely because
we are not in the right mode doesn't help first-time users figure
out what to do to correct things. Although the documentation for
QMP calls out capabilities negotiation, we should also make it
clear in our error messages what we were expecting. With this
patch, I now get the following transcript:
$ ./x86_64-softmmu/qemu-system-x86_64 -qmp stdio -nodefaults
{"QMP": {"version": {"qemu": {"micro": 93, "minor": 2, "major": 2}, "package": ""}, "capabilities": []}}

{"execute":"quit"}
{"error": {"class": "CommandNotFound", "desc": "Expecting capabilities negotiation with 'qmp_capabilities' before command 'quit'"}}

{"return": {}}

As far as the QMP parser is concerned, neither the 'O' nor the 'q' format specifiers
put any constraint on the command. However, there are two differences:
1) from a documentation point of view 'O' says that this command takes
a dictionary. The dictionary will be converted to QemuOpts in the
handler to match the corresponding HMP command.
2) 'O' sets QMP_ACCEPT_UNKNOWNS, resulting in the command accepting invalid
extra arguments. For example the following is accepted:
{ "execute": "send-key",
"arguments": { "keys": [ { "type": "qcode", "data": "ctrl" },
{ "type": "qcode", "data": "alt" },
{ "type": "qcode", "data": "delete" } ], "foo": "bar" } }
Neither send-key nor migrate-set-capabilities take a QemuOpts-like
dictionary; they take an array of dictionaries. And neither command
really wants to have extra unknown arguments. Thus, the right
specifier to use in this case is 'q'; with this patch the above
command fails with
{"error": {"class": "GenericError", "desc": "Invalid parameter 'foo'"}}
as intended.

Defaulting a parameter to True, then having all callers omit or
pass an explicit True for that parameter, is pointless. Looks
like it has been dead since introduction in commit 06d64c6, more
than 4 years ago.

A VM supports only one balloon device, but due to several changes
in infrastructure the error message got messed up when trying
to add a second device. Fix it.
Before this fix
Command-line:
qemu-qmp: -device virtio-balloon-pci,id=balloon0: Another balloon device already registered
qemu-qmp: -device virtio-balloon-pci,id=balloon0: Adding balloon handler failed
qemu-qmp: -device virtio-balloon-pci,id=balloon0: Device 'virtio-balloon-pci' could not be initialized
HMP:
Another balloon device already registered
Adding balloon handler failed
Device 'virtio-balloon-pci' could not be initialized
QMP:
{ "execute": "device_add", "arguments": { "driver": "virtio-balloon-pci", "id": "balloon0" } }
{
"error": {
"class": "GenericError",
"desc": "Adding balloon handler failed"
}
}
After this fix
Command-line:
qemu-qmp: -device virtio-balloon-pci,id=balloon0: Only one balloon device is supported
qemu-qmp: -device virtio-balloon-pci,id=balloon0: Device 'virtio-balloon-pci' could not be initialized
HMP:
(qemu) device_add virtio-balloon-pci,id=balloon0
Only one balloon device is supported
Device 'virtio-balloon-pci' could not be initialized
(qemu)
QMP:
{ "execute": "device_add",
"arguments": { "driver": "virtio-balloon-pci", "id": "balloon0" } }
{
"error": {
"class": "GenericError",
"desc": "Only one balloon device is supported"
}
}

Add a new function to get a nice label for a given QemuConsole.
Drop the labeling code in gtk.c and use the new function instead.

This way gtk has text terminal consoles even when building without vte.
Most notably you'll get a monitor tab on windows now.

The image field in BlockDeviceInfo should never be null, however
bdrv_block_device_info() is not filling it in.
This makes the 'info block -n -v' command crash QEMU.
The proper solution is probably to move the relevant code from
bdrv_query_info() to bdrv_block_device_info(), but since we're too
close to the release for that this simpler workaround solves the
crash.
