virtio-{blk,balloon,net,serial} are aliases for their actual,
architecture-dependent implementations (*-ccw on s390x, *-pci on other
architectures supporting virtio). This makes it a lot easier to craft
qemu invocations that work on all supported architectures. Complete
the set to cover all existing non-abstract virtio device classes.
For virtio-balloon, only the CCW implementation was missing.

When trying to instantiate an alias that points to a device class that
doesn't exist, the error message looks like qemu misunderstood the
request:
$ s390x-softmmu/qemu-system-s390x -device virtio-gpu
qemu-system-s390x: -device virtio-gpu: 'virtio-gpu-ccw' is not a valid
device model name
Special-case the error message to make it explicit that alias
expansion is going on:
$ s390x-softmmu/qemu-system-s390x -device virtio-gpu
qemu-system-s390x: -device virtio-gpu: 'virtio-gpu' (alias
'virtio-gpu-ccw') is not a valid device model name

Unlike ad hoc prints, error_report_err() uses the error whole instead
of just its message obtained with error_get_pretty(). This avoids
suppressing its hint (see commit 50b7b00). Example:
$ bld/ivshmem-server -l 42@
Parameter 'shm_size' expects a size
You may use k, M, G or T suffixes for kilobytes, megabytes, gigabytes and terabytes.
The last line is new with this patch.
While there, drop a "cannot parse shm size: " message prefix; it's
redundant, because the error message proper is always of the form
"Parameter 'shm_size' expects ...".

Since commit 50b7b00, we have error_append_hint() to conveniently
accumulate Error member @hint. error_report_err() prints it with a
newline appended. Consequently, users of error_append_hint() need to
know whether theirs is the final line of the hint to decide whether it
needs a newline. Not a nice interface.
Change error_report_err() to print just the hint, and the (still few)
users of error_append_hint() to add the required newline.

This reverts commit 31bed5509dfcbdfc293154ce81086a4dbd7a80b6.
The reverted commit changed qdev_device_help() to reject abstract
devices and devices that have cannot_instantiate_with_device_add_yet
set, to fix crash bugs like -device x86_64-cpu,help.
Rejecting abstract devices makes sense: they're purely internal, and
the implementation of the help feature can't cope with them.
Rejecting non-pluggable devices makes less sense: even though you
can't use them with -device, the help may still be useful elsewhere,
for instance with -global. This is a regression: -device FOO,help
used to help even for FOO that aren't pluggable.
The previous two commits fixed the crash bug at a lower layer, so
reverting this one is now safe. Fixes the -device FOO,help
regression, except for the broken devices marked
cannot_even_create_with_object_new_yet. For those, the error message
is improved.
Example of a device where the regression is fixed:
$ qemu-system-x86_64 -device PIIX4_PM,help
PIIX4_PM.command_serr_enable=bool (on/off)
PIIX4_PM.multifunction=bool (on/off)
PIIX4_PM.rombar=uint32
PIIX4_PM.romfile=str
PIIX4_PM.addr=int32 (Slot and optional function number, example: 06.0 or 06)
PIIX4_PM.memory-hotplug-support=bool
PIIX4_PM.acpi-pci-hotplug-with-bridge-support=bool
PIIX4_PM.s4_val=uint8
PIIX4_PM.disable_s4=uint8
PIIX4_PM.disable_s3=uint8
PIIX4_PM.smb_io_base=uint32
Example of a device where it isn't fixed:
$ qemu-system-x86_64 -device host-x86_64-cpu,help
Can't list properties of device 'host-x86_64-cpu'
Both failed with "Parameter 'driver' expects pluggable device type"

Currently device_del requires that the client provide the
device short ID. device_add allows devices to be created
without giving an ID, at which point there is no way to
delete them with device_del. The QOM object path, however,
provides an alternative way to identify the devices.
Allowing device_del to accept an object path ensures all
devices are deletable regardless of whether they have an
ID.

(qemu) qom-list /machine/peripheral-anon
device[0] (child<usb-mouse>)

Commits 7216ae3d and d2828429 disabled some error message hints,
all because a change to use modern error reporting meant that the
hint would be output prior to the actual error. Fix this by making
hints a first-class member of Error.
For example, we are now back to the pleasant:

qemu-system-x86_64: --chardev null,id=,: Parameter 'id' expects an identifier

The traditional QMP command handler interface
int qmp_FOO(Monitor *mon, const QDict *params, QObject **ret_data);
doesn't provide for returning an Error object. Instead, the handler
is expected to stash it in the monitor with qerror_report().
When we rebased QMP on top of QAPI, we didn't change this interface.
Instead, commit 776574d introduced "middle mode" as a temporary aid
for converting existing QMP commands to QAPI one by one. More than
three years later, we're still using it.
Middle mode has two effects:
* Instead of the native input marshallers
static void qmp_marshal_input_FOO(QDict *, QObject **, Error **)
it generates input marshallers conforming to the traditional QMP
command handler interface.
* It suppresses generation of code to register them with
qmp_register_command()
This permits giving them internal linkage.
As long as we need qmp-commands.hx, we can't use the registry behind
qmp_register_command(), so the latter has to stay for now.
The former has to go to get rid of qerror_report(). Changing all QMP
commands to fit the QAPI mold in one go was impractical back when we
started, but by now there are just a few stragglers left:
do_qmp_capabilities(), qmp_qom_set(), qmp_qom_get(), qmp_object_add(),
qmp_netdev_add(), do_device_add().
Switch middle mode to generate native input marshallers, and adapt the
stragglers. Simplifies both the monitor code and the stragglers.
Rename do_qmp_capabilities() to qmp_capabilities(), and
do_device_add() to qmp_device_add, because that's how QMP command
handlers are named today.

The error class is always ERROR_CLASS_GENERIC_ERROR since the previous
commit.

* Prepend every use of a QERR_ macro by ERROR_CLASS_GENERIC_ERROR, and
delete it from the QERR_ macro. No change after preprocessing.
* Rewrite error_set(ERROR_CLASS_GENERIC_ERROR, ...) into
error_setg(...). Again, no change after preprocessing.

qerror_report_err() is a transitional interface to help with
converting existing monitor commands to QMP. It should not be used
elsewhere.
The only remaining user in qemu-option.c is qemu_opts_parse(). Is it
used in QMP context? If not, we can simply replace
qerror_report_err() by error_report_err().
The uses in qemu-img.c, qemu-io.c, qemu-nbd.c and under tests/ are
clearly not in QMP context.
The uses in vl.c aren't either, because the only QMP command handlers
there are qmp_query_status() and qmp_query_machines(), and they don't
call it.
Remaining uses:
* drive_def(): Command line -drive and such, HMP drive_add and pci_add
* hmp_chardev_add(): HMP chardev-add
* monitor_parse_command(): HMP core
* tmp_config_parse(): Command line -tpmdev
* net_host_device_add(): HMP host_net_add
* net_client_parse(): Command line -net and -netdev
* qemu_global_option(): Command line -global
* vnc_parse_func(): Command line -display, -vnc, default display, HMP
change, QMP change. Bummer.
* qemu_pci_hot_add_nic(): HMP pci_add
* usb_net_init(): Command line -usbdevice, HMP usb_add
Propagate errors through qemu_opts_parse(). Create a convenience
function qemu_opts_parse_noisily() that passes errors to
error_report_err(). Switch all non-QMP users outside tests to it.
That leaves vnc_parse_func(). Propagate errors through it. Since I'm
touching it anyway, rename it to vnc_parse().

Property bus has always been too screwed up to be really usable for
values other than plain bus IDs. This just fixes a bug that crept in
in commit 1395af6 "qdev: add a maximum device allowed field for the
bus."
It doesn't always fail when it should:
$ qemu-system-x86_64 -nodefaults -device virtio-serial-pci -device virtio-rng-device,bus=pci.0/virtio-serial-pci/virtio-bus
Happily plugs the virtio-rng-device into the virtio-bus provided by
virtio-serial-pci, even though its only slot is already occupied by a
virtio-serial-device.
And sometimes fails when it shouldn't:
$ qemu-system-x86_64 -nodefaults -device virtio-serial-pci -device virtserialport,bus=virtio-bus/virtio-serial-device
Yes, the virtio-bus is full, but the virtio-serial-bus provided by
virtio-serial-device isn't, and that's the one we're trying to use.
Root cause: we check "bus full" when we resolve the first element of
the path. That's the correct one only when it's also the last one.
Fix by moving the "bus full" check to right before we return a bus.

qbus_find_recursive() reports the "is full" error itself, and leaves
reporting "not found" to its caller. The result is confusion. Write
it a function contract that permits leaving all error reporting to the
caller, and implement it. Update callers to detect and report "is
full".
Screwed up when commit 1395af6 added the max_dev limit and the "is

device_add puts every device with 'id' inside of 'peripheral'
container using id's value as the last component name.
Use it by replacing recursive search on sysbus with path
lookup in 'peripheral' container, which could handle both
BUS and BUS-less device cases.

It will allow explicitly mark device as not hotpluggable and
avoid its creation with following error at realize time
and destroying it afterwards anyway. Instead of it will
error out even before instance of device is created.

Normally, qmp_device_list_properties() may return NULL when
a device haven't special properties excpet Object and DeviceState
properties, such as virtio-balloon-device.
We just need check local_err instead of prop_list.
Example:
Segmentation fault (core dumped)
The backtrace as below:
Program received signal SIGSEGV, Segmentation fault.

Update -device FOO,help to include QOM properties in addition to qdev
properties. Devices are gradually adding more QOM properties that are
not reflected as qdev properties.
It is important to report all device properties since management tools
like libvirt use this information (and device-list-properties QMP) to
detect the presence of QEMU features.
This patch reuses the device-list-properties QMP machinery to avoid code
duplication.

Implement named GPIOs on the Device layer. Listifies the existing GPIOs
stuff using string keys. Legacy un-named GPIOs are preserved by using
a NULL name string - they are just a single matchable element in the

Test steps:
(qemu) device_add e1000,addr=adsf
Property 'e1000.addr' doesn't take value 'adsf'
(qemu) info qtree
Then qemu crashed.
Currently we set a link to the new device from its parent bus, but the
device hasn't been added to QOM tree yet. When it fails to set properties,
object_unparent() can't clean up the device.
Delay setting of device properties until the device has been added to
the QOM composition tree. This way, when setting a property fails,
object_unparent() can clean up the device properly.

error_is_set(&var) is the same as var != NULL, but it takes
whole-program analysis to figure that out. Unnecessarily hard for
optimizers, static checkers, and human readers. Dumb it down to
obvious.
Gets rid of several dozen Coverity false positives.
Note that the obvious form is already used in many places.
