303c33e606 ramfb: add migration support
Implementing RAMFB migration is quite straightforward. One caveat is to
treat the whole RAMFBCfg as a blob, since that's what is exposed to the
guest directly. This avoid having to fiddle with endianness issues if we
were to migrate fields individually as integers.

The devices using RAMFB will have to include ramfb_vmstate in their
migration description.

c0f527f4cc vfio/pci: Remove vfio_detach_device from vfio_realize error path
In vfio_realize, on the error path, we currently call
vfio_detach_device() after a successful vfio_attach_device.
While this looks natural, vfio_instance_finalize also induces
a vfio_detach_device(), and it seems to be the right place
instead as other resources are released there which happen
to be a prerequisite to a successful UNSET_CONTAINER.

So let's rely on the finalize vfio_detach_device call to free
all the relevant resources.

fde4dbb7e6 vfio/pci: Fix a potential memory leak in vfio_listener_region_add
When there is an failure in vfio_listener_region_add() and the section
belongs to a ram device, there is an inaccurate error report which should
never be related to vfio_dma_map failure. The memory holding err is also
incrementally leaked in each failure.

Fix it by reporting the real error and free it.

7103ef7e76 vfio/common: Introduce a per container device list
Several functions need to iterate over the VFIO devices attached to
a given container.  This is currently achieved by iterating over the
groups attached to the container and then over the devices in the group.
Let's introduce a per container device list that simplifies this
search.

Per container list is used in below functions:
vfio_devices_all_dirty_tracking
vfio_devices_all_device_dirty_tracking
vfio_devices_all_running_and_mig_active
vfio_devices_dma_logging_stop
vfio_devices_dma_logging_start
vfio_devices_query_dirty_bitmap

This will also ease the migration of IOMMUFD by hiding the group
specificity.

5456b1867d vfio/pci: Introduce vfio_[attach/detach]_device
We want the VFIO devices to be able to use two different
IOMMU backends, the legacy VFIO one and the new iommufd one.

Introduce vfio_[attach/detach]_device which aim at hiding the
underlying IOMMU backend (IOCTLs, datatypes, ...).

Once vfio_attach_device completes, the device is attached
to a security context and its fd can be used. Conversely
When vfio_detach_device completes, the device has been
detached from the security context.

At the moment only the implementation based on the legacy
container/group exists. Let's use it from the vfio-pci device.
Subsequent patches will handle other devices.

We also take benefit of this patch to properly free
vbasedev->name on failure.

528148980a configure: define "pkg-config" in addition to "pkgconfig"
Meson used to allow both "pkgconfig" and "pkg-config" entries in machine
files; the former was used for dependency lookup and the latter
was used as return value for "find_program('pkg-config')", which is a less
common use-case and one that QEMU does not need.

This inconsistency is going to be fixed by Meson 1.3, which will deprecate
"pkgconfig" in favor of "pkg-config" (the less common one, but it makes
sense because it matches the name of the binary). For backward
compatibility it is still allowed to define both, so do that in the
configure-generated machine file.

655e2a778d meson, cutils: allow non-relocatable installs
Say QEMU is configured with bindir = "/usr/bin" and a firmware path
that starts with "/usr/share/qemu".  Ever since QEMU 5.2, QEMU's
install has been relocatable: if you move qemu-system-x86_64 from
/usr/bin to /home/username/bin, it will start looking for firmware in
/home/username/share/qemu.  Previously, you would get a non-relocatable
install where the moved QEMU will keep looking for firmware in
/usr/share/qemu.

Windows almost always wants relocatable installs, and in fact that
is why QEMU 5.2 introduced relocatability in the first place.
However, newfangled distribution mechanisms such as AppImage
(https://docs.appimage.org/reference/best-practices.html), and
possibly NixOS, also dislike using at runtime the absolute paths
that were established at build time.

On POSIX systems you almost never care; if you do, your usecase
dictates which one is desirable, so there's no single answer.
Obviously relocatability works fine most of the time, because not many
people have complained about QEMU's switch to relocatable install,
and that's why until now there was no way to disable relocatability.

But a non-relocatable, non-modular binary can help if you want to do
experiments with old firmware and new QEMU or vice versa (because you
can just upgrade/downgrade the firmware package, and use rpm2cpio or
similar to extract the QEMU binaries outside /usr), so allow both.
This patch allows one to build a non-relocatable install using a new
option to configure.  Why?  Because it's not too hard, and because
it helps the user double check the relocatability of their install.

Note that the same code that handles relocation also lets you run QEMU
from the build tree and pick e.g. firmware files from the source tree
transparently.  Therefore that part remains active with this patch,
even if you configure with --disable-relocatable.
