The functions blk_log_writes_close(), blkverify_close(),
quorum_close(), vmdk_close() via vmdk_free_extents(), and other
bdrv_close() implementations call bdrv_graph_wrlock_drained(), which
must be called with the graph unlocked. They are reached via the
BlockDriver's bdrv_close() callback and the bdrv_close() wrapper,
which are also marked as GRAPH_UNLOCKED_PTR and GRAPH_UNLOCKED.
Furthermore, the function bdrv_close() also calls bdrv_drained_begin()
and bdrv_graph_wrlock_drained(), so there are additional reasons for
marking it GRAPH_UNLOCKED.

Many write-locked sections are also drained sections. A new
bdrv_graph_wrunlock_drained() wrapper around bdrv_graph_wrunlock() is
introduced, which will begin a drained section first. A global
variable is used so bdrv_graph_wrunlock() knows if it also needs
to end such a drained section. Both the aio_poll call in
bdrv_graph_wrlock() and the aio_bh_poll() in bdrv_graph_wrunlock()
can re-enter a write-locked section. While for the latter, ending the
drain could be moved to before the call, the former requires that the
variable is a counter and not just a boolean.
Since the wrapper calls bdrv_drain_all_begin(), which must be called
with the graph unlocked, mark the wrapper as GRAPH_UNLOCKED too.
The switch to the new helpers was generated with the following
commands and then manually checked:
find . -name '*.c' -exec sed -i -z 's/bdrv_drain_all_begin();\n\s*bdrv_graph_wrlock();/bdrv_graph_wrlock_drained();/g' {} ';'
find . -name '*.c' -exec sed -i -z 's/bdrv_graph_wrunlock();\n\s*bdrv_drain_all_end();/bdrv_graph_wrunlock();/g' {} ';'

All accesses of bs->quiesce_counter are in the main thread, either
after a GLOBAL_STATE_CODE() macro or in a function with GRAPH_WRLOCK
annotation.
This is essentially a revert of 414c2ec358 ("block: access
quiesce_counter with atomic ops"). At that time, neither the
GLOBAL_STATE_CODE() macro nor the GRAPH_WRLOCK annotation existed.
Even if the field was only accessed in the main thread back then (did
not check if that is actually the case), it wouldn't have been easy to
verify.

Recent patch [1] renames the save_live_complete_precopy handler to
save_complete, as the machine is not live in most cases when this
handler is executed. The same is true also for
save_live_complete_precopy_thread, therefore this patch removes the
"live" keyword from the handler itself and related types to keep the
naming unified.
In contrast to save_complete, this handler is only executed at the end
of precopy, therefore the "precopy" keyword is retained.

Allow virt arm machine to set the interrupt ID for the KVM
GIC maintenance interrupt.
This setting must be done before the KVM_DEV_ARM_VGIC_CTRL_INIT
hence the choice to perform the setting in the GICv3 realize
instead of proceeding the same way as kvm_arm_pmu_set_irq().

Code based on i386/pc enablement.
The memory layout places space for 16 host bridge register regions after
the GIC_REDIST2 in the extended memmap. This is a hole in the current
map so adding them here has no impact on placement of other memory regions
(tested with enough CPUs for GIC_REDIST2 to be in use.)
The high memory map is GiB aligned so the hole is there whatever the
size of memory or device_memory below this point.
The CFMWs are placed above the extended memmap. Note the existing
variable highest_gpa is the highest GPA that has been allocated at
a particular point in setting up the memory map. Whilst this caused
some confusion in review there are existing comments explaining this
so nothing is added.
The cxl_devices_state.host_mr provides a small space in which to place
the individual host bridge register regions for whatever host bridges are
allocated via -device pxb-cxl on the command line. The existing dynamic
sysbus infrastructure is not reused because pxb-cxl is a PCI device not
a sysbus one but these registers are directly in the main memory map,
not the PCI address space.
Only create the CEDT table if cxl=on set for the machine. Default to off.

Previously these somewhat device like structures were tracked using a list
in the CXLState in each machine. This is proving restrictive in a few
cases where we need to iterate through these without being aware of the
machine type. Just make them sysbus devices.
Restrict them to not user created as they need to be visible to early
stages of machine init given effects on the memory map.
This change both simplifies state tracking and enables features needed
for performance optimization and hotness tracking by making it possible
to retrieve the fixed memory window on actions elsewhere in the topology.
In some cases the ordering of the Fixed Memory Windows matters.
For those utility functions provide a GSList sorted by the window index.
This ensures that we get consistency across:
- ordering in the command line
- ordering of the host PA ranges
- ordering of ACPI CEDT structures describing the CFMWS.
Other aspects don't have this constraint. For those direct iteration
of the underlying hash structures is fine.
In the setup path for the memory map in pc_memory_init() split the
operations into two calls. The first, cxl_fmws_set_mmemap(), loops over
fixed memory windows in order and assigns their addresses. The second,
cxl_fmws_update_mmio() actually sets up the mmio for each window.
This is obviously less efficient than a single loop but this split design
is needed to put the logic in two different places in the arm64 support
and it is not a hot enough path to justify an x86 only implementation.

To enable these to be found in a fixed order, that order needs to be known.
This will later be used to sort a list of these structures so that address
map and ACPI table entries are predictable.
