ui/dbus: fix filtering all update messages

Filtering pending messages when a new scanout is given shouldn't discard

Since filtering happens in a different thread, use atomic set/get.

ui: refactor using a common qemu_pixman_shareable

Use a common shareable type for win32 & unix, and helper functions.
This simplify the code as it avoids a lot of #ifdef'ery.

Note: if it helps review, commits could be reordered to introduce the
common type before introducing shareable memory for unix.

ui/console: Use qemu_dmabuf_new() and free() helpers instead

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.).

ui/dbus: filter out pending messages when scanout

The "Listener" connection, being private and under the control of the
qemu display, allows for the optimization of discarding pending
intermediary messages when queuing a new scanout. This ensures that the
client receives only the latest scanout update, improving communication
efficiency.

While the current implementation does not provide a mechanism for
clients who may wish to receive all updates, making this behavior
optional could be considered in the future. For now, adopting this new
default behavior accelerates the communication process without a
guarantee of delivering all updates.

The filter is removed when the connection is dropped.

ui/dbus: implement damage regions for GL

Currently, when using `-display dbus,gl=on` all updates to the client
become "full scanout" updates, meaning there is no way for the client to
limit damage regions to the display server.

Instead of using an "update count", this patch tracks the damage region
and propagates it to the client.

This was less of an issue when clients were using GtkGLArea for
rendering,
as you'd be doing full-surface redraw. To be efficient, the client needs
both a DMA-BUF and the damage region to be updated.
