vfio: return mr from vfio_get_xlat_addr

Modify memory_get_xlat_addr and vfio_get_xlat_addr to return the memory
region that the translated address is found in. This will be needed by
CPR in a subsequent patch to map blocks using IOMMU_IOAS_MAP_FILE.

Also return the xlat offset, so we can simplify the interface by removing
the out parameters that can be trivially derived from mr and xlat.

Lastly, rename the functions to to memory_translate_iotlb() and
vfio_translate_iotlb().

vdpa: move memory listener register to vhost_vdpa_init

Current memory operations like pinning may take a lot of time at the
destination. Currently they are done after the source of the migration is
stopped, and before the workload is resumed at the destination. This is a
period where neigher traffic can flow, nor the VM workload can continue
(downtime).

We can do better as we know the memory layout of the guest RAM at the
destination from the moment that all devices are initializaed. So
moving that operation allows QEMU to communicate the kernel the maps
while the workload is still running in the source, so Linux can start
mapping them.

As a small drawback, there is a time in the initialization where QEMU
cannot respond to QMP etc. By some testing, this time is about
0.2seconds. This may be further reduced (or increased) depending on the
vdpa driver and the platform hardware, and it is dominated by the cost
of memory pinning.

This matches the time that we move out of the called downtime window.
The downtime is measured as the elapsed trace time between the last
vhost_vdpa_suspend on the source and the last vhost_vdpa_set_vring_enable_one
on the destination. In other words, from "guest CPUs freeze" to the
instant the final Rx/Tx queue-pair is able to start moving data.

Using ConnectX-6 Dx (MLX5) NICs in vhost-vDPA mode with 8 queue-pairs,
the series reduces guest-visible downtime during back-to-back live
migrations by more than half:
- 39G VM: 4.72s -> 2.09s (-2.63s, ~56% improvement)
- 128G VM: 14.72s -> 5.83s (-8.89s, ~60% improvement)

vdpa: reorder listener assignment

Since commit f6fe3e333f ("vdpa: move memory listener to
vhost_vdpa_shared") this piece of code repeatedly assign
shared->listener members. This was not a problem as it was not used
until device start.

However next patches move the listener registration to this
vhost_vdpa_init function. When the listener is registered it is added
to an embedded linked list, so setting its members again will cause
memory corruption to the linked list node.

Do the right thing and only set it in the first vdpa device.

vhost-iova-tree, svq: Implement GPA->IOVA & partial IOVA->HVA trees

Creates and supports a GPA->IOVA tree and a partial IOVA->HVA tree by
splitting up guest-backed memory maps and host-only memory maps from the
full IOVA->HVA tree. That is, any guest-backed memory maps are now
stored in the GPA->IOVA tree and host-only memory maps stay in the
IOVA->HVA tree.

Also propagates the GPAs (in_addr/out_addr) of a VirtQueueElement to
vhost_svq_translate_addr() to translate GPAs to IOVAs via the GPA->IOVA
tree (when descriptors are backed by guest memory). For descriptors
backed by host-only memory, the existing partial SVQ IOVA->HVA tree is
used.

GPAs are unique in the guest's address space, ensuring unambiguous IOVA
translations. This avoids the issue where different GPAs map to the same
HVA, causing the original HVA->IOVA translation to potentially return an
IOVA associated with the wrong intended GPA.

vhost-iova-tree: Implement an IOVA-only tree

Creates and supports an IOVA-only tree to support a SVQ IOVA->HVA and
GPA->IOVA tree for host-only and guest-backed memory, respectively, in
the next patch.

The IOVA allocator still allocates an IOVA range but now adds this range
to the IOVA-only tree as well as to the full IOVA->HVA tree.

In the next patch, the full IOVA->HVA tree will be split into a partial
SVQ IOVA->HVA tree and a GPA->IOVA tree. The motivation behind having an
IOVA-only tree was to have a single tree that would keep track of all
allocated IOVA ranges between the partial SVQ IOVA->HVA and GPA->IOVA
trees.

vdpa-dev: Fix initialisation order to restore VDUSE compatibility

VDUSE requires that virtqueues are first enabled before the DRIVER_OK
status flag is set; with the current API of the kernel module, it is
impossible to enable the opposite order in our block export code because
userspace is not notified when a virtqueue is enabled.

This requirement also mathces the normal initialisation order as done by
the generic vhost code in QEMU. However, commit 6c482547 accidentally
changed the order for vdpa-dev and broke access to VDUSE devices with
this.

This changes vdpa-dev to use the normal order again and use the standard
vhost callback .vhost_set_vring_enable for this. VDUSE devices can be
used with vdpa-dev again after this fix.

vhost_net intentionally avoided enabling the vrings for vdpa and does
this manually later while it does enable them for other vhost backends.
Reflect this in the vhost_net code and return early for vdpa, so that
the behaviour doesn't change for this device.
