This is a counterpart to the HMP "info opcount" command. It is being
added with an "x-" prefix because this QMP command is intended as an
ad hoc debugging tool and will thus not be modelled in QAPI as fully
structured data, nor will it have long term guaranteed stability.
The existing HMP command is rewritten to call the QMP command.

This provides a foundation on which to convert simple HMP commands to
use QMP. The QMP implementation will generate formatted text targeted
for human consumption, returning it in the HumanReadableText data type.
The HMP command handler will simply print out the formatted string
within the HumanReadableText data type. Since this will be an entirely
formulaic action in the case of HMP commands taking no arguments, a
custom command handler is provided.
Thus instead of registering a 'cmd' callback for the HMP command, a
'cmd_info_hrt' callback is provided, which will simply be a pointer
to the QMP implementation.

Without this the struct has the wrong size: sizeof() evaluates
to 16 instead of 13. In most cases the bug is hidden by the
fact that guests submits a buffer which is exactly 13 bytes
long, so the padding added by the compiler is simply ignored.
But sometimes guests submit a larger buffer and expect a short
transfer, which does not work properly with the wrong struct
size.

Any extra draw call for the same blob resource representing guest scanout
before the previous drawing is not finished can break synchronous draw
sequence. To prevent this, drawing is now done only once for each draw
submission (when draw_submitted == true).

Between the submission of a request and the unplug, other devices
with larger limits may have been queued new requests without flushing
the batch.
Using the new `dev_max_batch` parameter, laio_io_unplug() can check
if the batch exceeds the device limit to flush the current batch.

They're actually more commonly used than the helper without _under_bus, because
most callers do have the pci bus on hand. After exporting we can switch a lot
of the call sites to use these two helpers.

They're used in quite a few places of pci.[ch] and also in the rest of the code
base. Define them so that it doesn't need to be defined all over the places.
The pci_bus_fn is similar to pci_bus_dev_fn that only takes a PCIBus* and an
opaque. The pci_bus_ret_fn is similar to pci_bus_fn but it allows to return a
void* pointer.

We're about to support a third vIOMMU for x86, virtio-iommu which
doesn't inherit X86IOMMUState. Move the IOMMU singleton into
PCMachineState, so it can be shared between all three vIOMMUs.
The x86_iommu_get_default() helper is still needed by KVM and IOAPIC to
fetch the default IRQ-remapping IOMMU. Since virtio-iommu doesn't
support IRQ remapping, this interface doesn't need to change for the
moment. We could later replace X86IOMMUState with an "IRQ remapping
IOMMU" interface if necessary.

since dirty ring has been introduced, there are two methods
to track dirty pages of vm. it seems that "logging" has
a hint on the method, so rename the global_dirty_log to
global_dirty_tracking would make description more accurate.
dirty rate measurement may start or stop dirty tracking during
calculation. this conflict with migration because stop dirty
tracking make migration leave dirty pages out then that'll be
a problem.
make global_dirty_tracking a bitmask can let both migration and
dirty rate measurement work fine. introduce GLOBAL_DIRTY_MIGRATION
and GLOBAL_DIRTY_DIRTY_RATE to distinguish what current dirty
tracking aims for, migration or dirty rate.

dirty_pages is used to calculate dirtyrate via dirty ring, when
enabled, kvm-reaper will increase the dirty pages after gfns
being dirtied.
kvm_dirty_ring_enabled shows if kvm-reaper is working. dirtyrate
thread could use it to check if measurement can base on dirty
ring feature.

Now that we check sysbus device types during device creation, we
can remove the check in the machine init done notifier.
This was the only thing done by this notifier, so we remove the
whole sysbus_notifier structure of the MachineState.
Note: This notifier was checking all /peripheral and /peripheral-anon
sysbus devices. Now we only check those added by -device cli option or
device_add qmp command when handling the command/option. So if there
are some devices added in one of these containers manually (eg in
machine C code), these will not be checked anymore.
This use case does not seem to appear apart from
hw/xen/xen-legacy-backend.c (it uses qdev_set_id() and in this case,
not for a sysbus device, so it's ok).

Right now the allowance check for adding a sysbus device using
-device cli option (or device_add qmp command) is done well after
the device has been created. It is done during the machine init done
notifier: machine_init_notify() in hw/core/machine.c
This new function will allow us to do the check at the right time and
issue an error if it fails.
Also make device_is_dynamic_sysbus() use the new function.

We are going to introduce an unit test for the parser smp_parse()
in hw/core/machine.c, but now machine.c is only built in softmmu.
In order to solve the build dependency on the smp parsing code and
avoid building unrelated stuff for the unit tests, move the tested
code from machine.c into a separate file, i.e., machine-smp.c and
build it in common field.

New option parameters unstable-input and unstable-output set policy
for unstable interfaces just like deprecated-input and
deprecated-output set policy for deprecated interfaces (see commit
6dd75472d5 "qemu-options: New -compat to set policy for deprecated
interfaces"). This is intended for testing users of the management
interfaces. It is experimental.
For now, this covers only syntactic aspects of QMP, i.e. stuff tagged
with feature 'unstable'. We may want to extend it to cover semantic
aspects, or the command line.
Note that there is no good way for management application to detect
presence of these new option parameters: they are not visible output
of query-qmp-schema or query-command-line-options. Tolerable, because
it's meant for testing. If running with -compat fails, skip the test.

The code to check enumeration value policy can see special feature
flag 'deprecated' in QEnumLookup member flags[value]. I want to make
feature flag 'unstable' visible there as well, so I can add policy for

Instead of extending flags[], replace it by @special_features (a
bitset of QapiSpecialFeature), because that's how special features get
passed around elsewhere.

The code to check command policy can see special feature flag

To let me make it visible, add member @special_features (a bitset of
QapiSpecialFeature) to QmpCommand, and adjust the generator to pass it
through qmp_register_command(). Then replace "QCO_DEPRECATED in
@flags" by QAPI_DEPRECATED in @special_features", and drop
QCO_DEPRECATED.

The generated visitor functions call visit_deprecated_accept() and
visit_deprecated() when visiting a struct member with special feature
flag 'deprecated'. This makes the feature flag visible to the actual
visitors. I want to make feature flag 'unstable' visible there as
well, so I can add policy for it.
To let me make it visible, replace these functions by
visit_policy_reject() and visit_policy_skip(), which take the member's
special features as an argument. Note that the new functions have the
opposite sense, i.e. the return value flips.
