linker-loader: Add new 'write pointer' command
This is similar to the existing 'add pointer' functionality, but instead
of instructing the guest (BIOS or UEFI) to patch memory, it instructs
the guest to write the pointer back to QEMU via a writeable fw_cfg file.

ACPI: Add vmgenid blob storage to the build tables
This allows them to be centrally initialized and destroyed
The "AcpiBuildTables.vmgenid" array will be used to construct the
"etc/vmgenid_guid" fw_cfg blob.
Its contents will be linked into fw_cfg after being built on the
pc_machine_done() -> acpi_setup() -> acpi_build() call path, and dropped
without use on the subsequent, guest triggered, acpi_build_update() ->
acpi_build() call path.

ACPI: Add Virtual Machine Generation ID support
This implements the VM Generation ID feature by passing a 128-bit
GUID to the guest via a fw_cfg blob.
Any time the GUID changes, an ACPI notify event is sent to the guest
The user interface is a simple device with one parameter:
- guid (string, must be "auto" or in UUID format
xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx)

virtio: guard vring access when setting notification
Switching to vring caches exposed an existing bug in
virtio_queue_set_notification(): We can't access vring structures
if they have not been set up yet. This may happen, for example,
for virtio-blk devices with multiple queues: The code will try to
switch notifiers for every queue, but the guest may have only set up
a subset of them.
Fix this by guarding access to the vring memory by checking for
vring.desc. The first aio poll will iron out any remaining
inconsistencies for later-configured queues (buggy legacy drivers).

virtio: add missing region cache init in virtio_load()
Commit 97cd965c070152bc626c7507df9fb356bbe1cd81 ("virtio: use
VRingMemoryRegionCaches for avail and used rings") switched to a memory
region cache to avoid repeated map/unmap operations.
The virtio_load() process is a little tricky because vring addresses are
serialized in two separate places. VIRTIO 1.0 devices serialize desc
and then a subsection with used and avail. Legacy devices only
serialize desc.
Live migration of VIRTIO 1.0 devices fails on the destination host with:
VQ 0 size 0x80 < last_avail_idx 0x12f8 - used_idx 0x0
Failed to load virtio-blk:virtio
error while loading state for instance 0x0 of device '0000:00:04.0/virtio-blk'
This happens because the memory region cache is only initialized after
desc is loaded and not after the used and avail subsection is loaded.
If the guest chose memory addresses that don't match the legacy ring
layout then the wrong guest memory location is accessed.
Wait until all ring addresses are known before trying to initialize the
region cache. Also clarify the incomplete comment about VIRTIO-1 ring
address subsection.

virtio: unbreak virtio-pci with IOMMU after caching ring translations
Commit c611c76417f5 ("virtio: add MemoryListener to cache ring
translations") registers a memory listener to dma_as. This may not
work when IOMMU is enabled: dma_as(bus_master_as) were initialized in
pcibus_machine_done() after virtio_realize(). This will cause a
segfault. Fixing this by using pci_device_iommu_address_space()
instead to make sure address space were initialized at this time.
With this fix, IOMMU device were required to be initialized before any
virtio-pci devices.

see 6.2.9.1 OSC Implementation Example for PCI Host Bridge Devices, ACPI 3.0a:
It is recommended that a machine with multiple host bridge devices
should report the same capabilities for all host bridges, and also
negotiate control of the features described in the Control Field in
the same way for all host bridges.
