The SASL library requires the connection's local & remote IP address to
be passed in, since some mechanism may use this information. Currently
QEMU raises an error for non-inet sockets, but it is valid to pass NULL
to the SASL library. Doing so makes SASL work on UNIX sockets.

The SASL initialization phase may determine that there are no valid
mechanisms available to use. This may be because the host OS admin
forgot to install some packages, or it might be because the requested
SSF level is incompatible with available mechanisms, or other unknown
reasons.
If we return an empty mechlist to the client, they're going to get a
failure from the SASL library on their end and drop the connection.
Thus there is no point even sending this back to the client, we can
just drop the connection immediately.

The ``-portrait`` and ``-rotate`` options were documented as only
working with the PXA LCD device, and all the machine types using
that display device were removed in 9.2.
These options were intended to simulate a mobile device being
rotated by the user, and had three effects:
* the display output was rotated by 90, 180 or 270 degrees
(implemented in the PXA display device models)
* the mouse/trackpad input was rotated the opposite way
(implemented in generic code)
* the machine model would signal to the guest about its
orientation
(implemented by e.g. the spitz machine model)
Of these three things, the input-rotation was coded without being
restricted to boards which supported the full set of device-rotation
handling, so in theory the options were usable on other machine
models with odd effects (rotating input but not display output). But
this was never intended or documented behaviour, so we can reasonably
drop these command line arguments without a formal deprecate-and-drop
cycle for them.
Remove the options, and their implementation and documentation.
Describe the removal in removed-features.rst.

Each virtual console in the SDL2 frontend has a key state map.
When switching windows with GUI keys we have to release all
pressed modifier keys in the currently active window, because
after the switch the now inactive window no longer receives the
key release events.
To reproduce the issue open a text editor in the SDL UI and then
press Ctrl-Alt-2 to open a Compat Monitor Console. Close the
console with the mouse. Try to enter text in the text editor and
notice that the modifier keys Ctrl and Alt are stuck and need to
be pressed once to be released.

Mouse cursors with 8 bit alpha were downsampled to 1-bit opacity maps by
turning alpha values of 255 into 1 and everything else into 0. This
means that mostly-opaque pixels ended up completely invisible.
This patch changes the behaviour so that only pixels with less than 50%
alpha (0-127) are treated as transparent when converted to 1-bit alpha.
This greatly improves the subjective appearance of anti-aliased mouse
cursors, such as those used by macOS, when using a front-end UI without
support for alpha-blended cursors, such as some VNC clients.

Remove dpy_cursor_define_supported() as it brings no benefit today and
it has a few inherent problems.
All graphical displays except egl-headless support cursor composition
without DMA-BUF, and egl-headless is meant to be used in conjunction
with another graphical display, so dpy_cursor_define_supported()
always returns true and meaningless.
Even if we add a new display without cursor composition in the future,
dpy_cursor_define_supported() will be problematic as a cursor display
fix for it because some display devices like virtio-gpu cannot tell the
lack of cursor composition capability to the guest and are unable to
utilize the value the function returns. Therefore, all non-headless
graphical displays must actually implement cursor composition for
correct cursor display.
Another problem with dpy_cursor_define_supported() is that it returns
true even if only some of the display listeners support cursor
composition, which is wrong unless all display listeners that lack
cursor composition is headless.

Add accelerated cursor composition to ui/cocoa. This does not only
improve performance for display devices that exposes the capability to
the guest according to dpy_cursor_define_supported(), but fixes the
cursor display for devices that unconditionally expects the availability
of the capability (e.g., virtio-gpu).
The common pattern to implement accelerated cursor composition is to
replace the cursor and warp it so that the replaced cursor is shown at
the correct position on the guest display for relative pointer devices.
Unfortunately, ui/cocoa cannot do the same because warping the cursor
position interfers with the mouse input so it uses CALayer instead;
although it is not specialized for cursor composition, it still can
compose images with hardware acceleration.

Remove gtk_widget_get_scale_factor() usage from the calculation of
the motion events in the GTK backend to make it work correctly on
environments that have `gtk_widget_get_scale_factor() != 1`.
This scale factor usage had been introduced in the commit f14aab420c and
at that time the window size was used for calculating the things and it
was working correctly. However, in the commit 2f31663ed4 the logic
switched to use the widget size instead of window size and because of
the change the usage of scale factor becomes invalid (since widgets use
`vc->gfx.scale_{x, y}` for scaling).
Tested on Crostini on ChromeOS (15823.51.0) with an external display.

This commit introduces utility functions for the creation and deallocation
of QemuDmaBuf instances. Additionally, it updates all relevant sections
of the codebase to utilize these new utility functions.
v7: remove prefix, "dpy_gl_" from all helpers
qemu_dmabuf_free() returns without doing anything if input is null
(Daniel P. Berrangé <berrange@redhat.com>)
call G_DEFINE_AUTOPTR_CLEANUP_FUNC for qemu_dmabuf_free()
(Daniel P. Berrangé <berrange@redhat.com>)
v8: Introduction of helpers was removed as those were already added
by the previous commit
v9: set dmabuf->allow_fences to 'true' when dmabuf is created in
virtio_gpu_create_dmabuf()/virtio-gpu-udmabuf.c
removed unnecessary spaces were accidently added in the patch,
'ui/console: Use qemu_dmabuf_new() a...'
v11: Calling qemu_dmabuf_close was removed as closing dmabuf->fd will be
done in qemu_dmabuf_free anyway.
(Daniel P. Berrangé <berrange@redhat.com>)
v12: --- Calling qemu_dmabuf_close separately as qemu_dmabuf_free doesn't
do it.
--- 'dmabuf' is now allocated space so it should be freed at the end of
dbus_scanout_texture
v13: --- Immediately free dmabuf after it is released to prevent possible
leaking of the ptr
(Marc-André Lureau <marcandre.lureau@redhat.com>)
--- Use g_autoptr macro to define *dmabuf for auto clean up instead of
calling qemu_dmabuf_free
(Marc-André Lureau <marcandre.lureau@redhat.com>)
v14: --- (vhost-user-gpu) Change qemu_dmabuf_free back to g_clear_pointer
as it was done because of some misunderstanding (v13).
--- (vhost-user-gpu) g->dmabuf[m->scanout_id] needs to be set to NULL
to prevent freed dmabuf to be accessed again in case if(fd==-1)break;
happens (before new dmabuf is allocated). Otherwise, it would cause
invalid memory access when the same function is executed. Also NULL
check should be done before qemu_dmabuf_close (it asserts dmabuf!=NULL.).
