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.).

New header and source files are added for containing QemuDmaBuf struct
definition and newly introduced helpers for creating/freeing the struct
and accessing its data.
v10: Change the license type for both dmabuf.h and dmabuf.c from MIT to
GPL to be in line with QEMU's default license
v11: -- Added new helpers, qemu_dmabuf_close for closing dmabuf->fd,
qemu_dmabuf_dup_fd for duplicating dmabuf->fd
(Daniel P. Berrangé <berrange@redhat.com>)
-- Let qemu_dmabuf_fee to call qemu_dmabuf_close before freeing
the struct to make sure fd is closed.
(Daniel P. Berrangé <berrange@redhat.com>)
v12: Not closing fd in qemu_dmabuf_free because there are cases fd
should still be available even after the struct is destroyed
(e.g. virtio-gpu: res->dmabuf_fd).

Now that we switched all consumers of the URI code to use the URI
parsing functions from glib instead, we can remove our internal

Now that we dropped support for CentOS 8 and Ubuntu 20.04, we can
look into bumping the glib version to a new minimum for further
clean-ups. According to repology.org, available versions are:
CentOS Stream 9: 2.66.7
Debian 11: 2.66.8
Fedora 38: 2.74.1
Freebsd: 2.78.4
Homebrew: 2.80.0
Openbsd: 2.78.4
OpenSuse leap 15.5: 2.70.5
pkgsrc_current: 2.78.4
Ubuntu 22.04: 2.72.1
Thus it should be safe to bump the minimum glib version to 2.66 now.
Version 2.66 comes with new functions for URI parsing which will
allow further clean-ups in the following patches.

The rtc-reset-reinjection QMP command is specific to x86, other boards do not
have the ACK tracking functionality that is needed for RTC interrupt
reinjection. Therefore the QMP command is only included in x86, but
qmp_rtc_reset_reinjection() is implemented by hw/rtc/mc146818rtc.c
and requires tracking of all created RTC devices. Move the implementation
to hw/i386, so that 1) it is available even if no RTC device exist
2) the only RTC that exists is easily found in x86ms->rtc.

It is okay to register legacy backends in the middle of xen_bus_init().
All that the registration does is record the existence of the backend
in xenstore.
This makes it possible to remove them from the build without introducing
undefined symbols in xen_be_init(). It also removes the need for the
backend_register callback, whose only purpose is to avoid registering
nonfunctional backends.

The CSS subsystem uses global variables, just face the truth and use
a variable also for whether the CSS vmstate is in use; remove the
indirection of fetching it from the machine type, which makes the
TCG code depend unnecessarily on the virtio-ccw machine.
