The patch adds "show_tabs" command line option for GTK ui similar to
"grab_on_hover". This option allows tabbed view mode to not have to be

Retrieve the refresh rate of the display and reflect it with
dpy_set_ui_info() and update_displaychangelistener(), allowing the
guest and DisplayChangeListener to consume the information.
The information will be used as a hint how often the display should
be updated. For example, when we run 30 Hz physical display updates
it is pointless for the guest to update the screen at 60Hz
frequency, the guest can spare some work instead.

I noticed this error while building QEMU on Mac OS X:
[1040/1660] Compiling Objective-C object libcommon.fa.p/ui_cocoa.m.o
../ui/cocoa.m:803:17: warning: variable 'switched_to_fullscreen' set but not used [-Wunused-but-set-variable]
static bool switched_to_fullscreen = false;
^
1 warning generated.
I think the behavior is fine if you remove "switched_to_fullscreen", I can
still switch in and out of mouse grabbed mode and fullscreen mode with this
change, and Command keycodes will only be passed to the guest if the mouse
is grabbed, which I think is the right behavior. I'm not sure why a static
piece of state was needed to handle that in the first place. Perhaps the
refactoring of the flags-state-change fixed that by toggling the Command
keycode on.
I tested this with an Ubuntu core image on macOS 12.4

This change adds a new member, refresh_rate to QemuUIInfo in
include/ui/console.h. It represents the refresh rate of the
physical display backend, and it is more appropriate than
GUI update interval as the refresh rate which the emulated device
reports:
- sdl may set GUI update interval shorter than the refresh rate
of the physical display to respond to user-generated events.
- sdl and vnc aggressively changes GUI update interval, but
a guests is typically not designed to respond to frequent
refresh rate changes, or frequent "display mode" changes in
general. The frequency of refresh rate changes of the physical
display backend matches better to the guest's expectation.
QemuUIInfo also has other members representing "display mode",
which makes it suitable for refresh rate representation. It has
a throttling of update notifications, and prevents frequent changes
of the display mode.

Since about 2018 virglrenderer (commit fa835b0f88 "vrend: don't
hardcode context version") tries to open the highest available GL
context version. This is done by creating the known GL context
versions from the highest to the lowest until (*create_gl_context)
returns a context != NULL.
This does not work properly with
the current QEMU gd_gl_area_create_context() function, because
gdk_gl_context_realize() on Wayland creates a version 3.0 legacy
context if the requested GL context version can't be created.
In order for virglrenderer to find the highest available GL
context version, return NULL if the created context version is
lower than the requested version.
This fixes the following error:
QEMU started with -device virtio-vga-gl -display gtk,gl=on.
Under Wayland, the guest window remains black and the following
information can be seen on the host.

The "-display sdl" option still uses a hand-crafted parser for its
parameters since we didn't want to drag an interface we considered
somewhat flawed into the QAPI schema. Since the flaws are gone now,
it's time to QAPIfy.
This introduces the new "DisplaySDL" QAPI struct that is used to hold
the parameters that are unique to the SDL display. The only specific
parameter is currently "grab-mod" that is used to specify the required
modifier keys to escape from the mouse grabbing mode.

'blockdev-change-medium' is a convinient wrapper for the following
sequence of commands:
* blockdev-open-tray
* blockdev-remove-medium
* blockdev-insert-medium
* blockdev-close-tray
and should be used f.e. to change ISO image inside the CD-ROM tray.
Though the guest could lock the tray and some linux guests like
CentOS 8.5 actually does that. In this case the execution if this
command results in the error like the following:
Device 'scsi0-0-1-0' is locked and force was not specified,
wait for tray to open and try again.
This situation is could be resolved 'blockdev-open-tray' by passing
flag 'force' inside. Thus is seems reasonable to add the same
capability for 'blockdev-change-medium' too.

On Mac OS X the Option key maps to Alt and Command to Super/Meta. This change
swaps them around so that Alt is the key closer to the space bar and Meta/Super
is between Control and Alt, like on non-Mac keyboards.
It is a cocoa display option, disabled by default.

Applications such as Gnome may use Alt-Tab and Super-Tab for different
purposes, some use Ctrl-arrows so we want to allow qemu to handle
everything when it captures the mouse/keyboard.
However, Mac OS handles some combos like Command-Tab and Ctrl-arrows
at an earlier part of the event handling chain, not letting qemu see it.
We add a global Event Tap that allows qemu to see all events when the
mouse is grabbed. Note that this requires additional permissions.

This resolves an issue where using command-tab to switch between QEMU
and other windows on the host can leave the mouse pointer visible.
By releasing the mouse when the user switches away, the user must left
click on the QEMU window when switching back in order to hide the
pointer and return control to the guest.
This appraoch ensures that the calls to NSCursor hide and unhide are
always balanced and thus work correctly when invoked.

When switching between guest and host on a Mac using command-tab the
command key is sent to the guest which can trigger functionality in the
guest OS. Specifying left-command-key=off disables forwarding this key
to the guest. Defaults to enabled.

left-command-key option along with the existing show-cursor option.

qemu_console_resize() will create a blank surface and replace the
current scanout with it if called while the current scanout is
GL (texture or dmabuf).
This is not only very costly, but also can produce glitches on the
display/listener side.
Instead, compare the current console size with the fitting console
functions, which also works when the scanout is GL.
Note: there might be still an unnecessary surface creation on calling
qemu_console_resize() when the size is actually changing, but display
backends currently rely on DisplaySurface details during
dpy_gfx_switch() to handle various resize aspects. We would need more
refactoring to handle resize without DisplaySurface, this is left for a
future improvement.

In commit 6e657e64cd in 2013 we added some autorelease pools to
deal with complaints from macOS when we made calls into Cocoa from
threads that didn't have automatically created autorelease pools.
Later on, macOS got stricter about forbidding cross-thread Cocoa
calls, and in commit 5588840ff7 we restructured the code to
avoid them. This left the autorelease pool creation in several
functions without any purpose; delete it.
We still need the pool in cocoa_refresh() for the clipboard related
code which is called directly there.

The updateUIInfo method makes Cocoa API calls. It also calls back
into QEMU functions like dpy_set_ui_info(). To do this safely, we
need to follow two rules:
* Cocoa API calls are made on the Cocoa UI thread
* When calling back into QEMU we must hold the iothread lock
Fix the places where we got this wrong, by taking the iothread lock
while executing updateUIInfo, and moving the call in cocoa_switch()
inside the dispatch_async block.
Some of the Cocoa UI methods which call updateUIInfo are invoked as
part of the initial application startup, while we're still doing the
little cross-thread dance described in the comment just above
call_qemu_main(). This meant they were calling back into the QEMU UI
layer before we'd actually finished initializing our display and
registered the DisplayChangeListener, which isn't really valid. Once
updateUIInfo takes the iothread lock, we no longer get away with
this, because during this startup phase the iothread lock is held by
the QEMU main-loop thread which is waiting for us to finish our
display initialization. So we must suppress updateUIInfo until
applicationDidFinishLaunching allows the QEMU main-loop thread to
continue.

setAllowedFileTypes is deprecated in macOS 12.
Per Akihiko Odaki [*]:
An image file, which is being chosen by the panel, can be a
raw file and have a variety of file extensions and many are not
covered by the provided list (e.g. "udf"). Other platforms like
GTK can provide an option to open a file with an extension not
listed, but Cocoa can't. It forces the user to rename the file
to give an extension in the list. Moreover, Cocoa does not tell
which extensions are in the list so the user needs to read the
source code, which is pretty bad.
Since this code is harming the usability rather than improving it,
simply remove the [NSSavePanel allowedFileTypes:] call, fixing:

From the call trace, we can see it is a deadlock bug.
vnc_disconnect_finish will acquire the output_mutex.
But, the output_mutex will be acquired again in vnc_clipboard_send.
Repeated locking will cause deadlock. So, I move
qemu_clipboard_peer_unregister() behind vnc_unlock_output();

Add an option to use direct connections instead of via the bus. Clients
are accepted with QMP add_client.
This allows to provide the D-Bus display without a bus. It also
simplifies the testing setup (some CI have issues to setup a D-Bus bus
in a container).

The "dbus" display backend exports the QEMU consoles and other
UI-related interfaces over D-Bus.
By default, the connection is established on the session bus, but you
can specify a different bus with the "addr" option.
The backend takes the "org.qemu" service name, while still allowing
further instances to queue on the same name (so you can lookup all the
available instances too). It accepts any number of clients at this
point, although this is expected to evolve with options to restrict
clients, or only accept p2p via fd passing.
The interface is intentionally very close to the internal QEMU API,
and can be introspected or interacted with busctl/dfeet etc:
$ ./qemu-system-x86_64 -name MyVM -display dbus
$ busctl --user introspect org.qemu /org/qemu/Display1/Console_0

GraphicHw.gl_flushed was introduced to notify the
device (vhost-user-gpu) that the GL resources (the display scanout) are
no longer needed.
It was decoupled from QEMU own gl-blocking mechanism, but that
difference isn't helping. Instead, we can reuse QEMU gl-blocking and
notify virtio_gpu_gl_flushed() when unblocking (to unlock
vhost-user-gpu).
An extra block/unblock is added arount dpy_gl_update() so existing
backends that don't block will have the flush event handled. It will
also help when there are no backends associated.

vnc_server_cut_text_caps() is not guaranteed to be called only once.
If it called twice, we finally call notifier_list_add() twice with same
element. Which leads to loopback QLIST. So, on next
notifier_list_notify() we'll loop forever and QEMU stuck.
So, let's only register new notifier if it's not yet registered.
Note, that similar check is used in vdagent_chr_recv_caps() (before
call qemu_clipboard_peer_register()), and also before
qemu_clipboard_peer_unregister() call in vdagent_disconnect() and in
vnc_disconnect_finish().

The dmabuf often becomes invalid right after unblocking pipeline
and graphic_hw_gl_flushed in case a new scanout blob is submitted
because the dmabuf associated with the current guest scanout is
freed after swapping.
So both graphic_hw_gl_block and graphic_hw_gl_flushed should be
executed after closing fence_fd for the current dmabuf.
