Turn Chardev into Object.
qemu_chr_alloc() is replaced by the qemu_chardev_new() constructor. It
will call qemu_char_open() to open/intialize the chardev with the
ChardevCommon *backend settings.
The CharDriver::create() callback is turned into a ChardevClass::open()
which is called from the newly introduced qemu_chardev_open().
"chardev-gdb" and "chardev-hci" are internal chardev and aren't
creatable directly with -chardev. Use a new internal flag to disable
them. We may want to use TYPE_USER_CREATABLE interface instead, or
perhaps allow -chardev usage.
Although in general we keep typename and macros private, unless the type
is being used by some other file, in this patch, all types and common
helper macros for qemu-char.c are in char.h. This is to help transition
now (some types must be declared early, while some aren't shared) and
when splitting in several units. This is to be improved later.

Adding one more option "-f" for "info mtree" to dump the flat views of
all the address spaces.
This will be useful to debug the memory rendering logic, also it'll be
much easier with it to know what memory region is handling what address
range.

Leave the implementation of error_vprintf and error_vprintf_unless_qmp
(the latter now trivially wrapped by error_printf_unless_qmp) to
libqemustub.a and monitor.c. This has two advantages: it lets us
remove the monitor_printf and monitor_vprintf stubs, and it lets
tests provide a different implementation of the functions that uses
g_test_message.

The QMP visitors have no direct dependency on QMP. It is
valid to use them anywhere that one has a QObject. Rename them
to better reflect their functionality as a generic QObject
to QAPI converter.
This is the first of three parts: rename the files. The next two
parts will rename C identifiers. The split is necessary to make git
rename detection work.

Now that all front end use qemu_chr_fe_init(), we can move chardev
claiming in init(), and add a function deinit() to release the chardev
and cleanup handlers.
The qemu_chr_fe_claim_no_fail() for property are gone, since the
property will raise an error instead. In other cases, where there is
already an error path, an error is raised instead. Finally, other cases
are handled by &error_abort in qemu_chr_fe_init().

Instead of requiring clients to actually call the query-cpu-*
commands to find out if they are implemented, remove them from
the output of "query-commands", so clients know they are not
available.
This is implemented by extending the existing hack at
qmp_unregister_commands_hack(). I wish I could avoid adding even
more #ifdefs to that code, but that's the solution we have today.

Now that we allow CPU hot unplug on a few platforms, we can end up in a
situation where we don't have a CPU with index 0. Or at least we could,
if we didn't have code to explicitly prohibit unplug of CPU 0.
Longer term we want to allow CPU 0 unplug, this patch is an early step in
allowing this, by removing an assumption in the monitor code that CPU 0
always exists.

We currently define QMP commands in two places: the QAPI schema and
qmp-commands.hx. The latter is preprocessed, the former is not. We
use the preprocessor to suppress configuration-specific commands. For
instance, query-spice is only available #ifdef CONFIG_SPICE.
QMP command dispatch and query-commands use the qmp-commands.hx
definition, and thus obey the #ifdeffery there. Good, because it lets
QMP clients probe for available features more easily.
query-qmp-schema uses the QAPI schema, and thus lists the
configuration-specific commands even when they're unavailable. Not so
good.
We're about to flip command dispatch and query-commands to the
non-middle-mode command registry, which uses the QAPI schema, so we
can ditch qmp-commands.hx. To avoid regressing query-commands,
arrange for commands that are suppressed with the preprocessor now to
be unregistered with that registry. This will keep them unavailable
and out of query-commands when we flip command dispatch and
query-commands to that registry, exactly as before.
This is a hack. The proper solution is to support
configuration-specific commands in the QAPI schema. Mark it FIXME.

Since a few commands are using 'gen': false, they are not registered
automatically by the generator. Register manually instead.
This is in preparation for removal of qapi 'middle' mode generation.
Note that qmp_init_marshal() function isn't run yet, so the commands
aren't actually registered, until module_call_init(MODULE_INIT_QAPI) is

This is a mostly-mechanical conversion that creates a new flat
union 'Netdev' QAPI type that covers all the branches of the
former 'NetClientOptions' simple union, where the branches are
now listed in a new 'NetClientDriver' enum rather than generated
from the simple union. The existence of a flat union has no
change to the command line syntax accepted for new code, and
will make it possible for a future patch to switch the QMP
command to parse a boxed union for no change to valid QMP; but
it does have some ripple effect on the C code when dealing with
the new types.
While making the conversion, note that the 'NetLegacy' type
remains unchanged: it applies only to legacy command line options,
and will not be ported to QMP, so it should remain a wrapper
around a simple union; to avoid confusion, the type named
'NetClientOptions' is now gone, and we introduce 'NetLegacyOptions'
in its place. Then, in the C code, we convert from NetLegacy to
Netdev as soon as possible, so that the bulk of the net stack
only has to deal with one QAPI type, not two. Note that since
the old legacy code always rejected 'hubport', we can just omit

'qjson.h' is not a QObject subtype; include this file directly in
.c files that are using it, rather than abusing qmp/types.h for
that purpose.
Meanwhile, for files that include a list of individual QObject
subtypes, it's easier to just use qmp/types.h for that purpose.

When qemu_set_log_filename() detects an invalid file name, it reports
an error, closes the log file (if any), and starts logging to stderr
(unless daemonized or nothing is being logged).
This is wrong. Asking for an invalid log file on the command line
should be fatal. Asking for one in the monitor should fail without
messing up an existing logfile.
Fix by converting qemu_set_log_filename() to Error. Pass it
&error_fatal, except for hmp_logfile report errors.
This also permits testing without a subprocess, so do that.

It will allow mgmt to query present and hotpluggable CPU objects,
it is required from a target platform that wishes to support command
to implement and set MachineClass.query_hotpluggable_cpus callback,
which will return a list of possible CPU objects with options that
would be needed for hotplugging possible CPU objects.
There are:
'type': 'str' - QOM CPU object type for usage with device_add
'vcpus-count': 'int' - number of logical VCPU threads per
CPU object (mgmt needs to know)
and a set of optional fields that are to used for hotplugging a CPU
objects and would allows mgmt tools to know what/where it could be
hotplugged;
[node],[socket],[core],[thread]
For present CPUs there is a 'qom-path' field which would allow mgmt to
inspect whatever object/abstraction the target platform considers
as CPU object.

The bdrv_next() users all leaked the BdrvNextIterator after completing
the iteration. Simply changing bdrv_next() to free the iterator before
returning NULL at the end of list doesn't work because some callers exit
the loop before looking at all BDSes.
This patch moves the BdrvNextIterator from the heap to the stack of
the caller and switches to a bdrv_first()/bdrv_next() interface for
initialising the iterator.

This patch add "query-gic-capabilities" but does not implement it. The
command is ARM-only. The command will return a list of GICCapability
structs that describes all GIC versions that current QEMU and system
support.
Libvirt is possibly the first consumer of this new command.
Before this patch, a libvirt user can successfully configure all kinds
of GIC devices for ARM guests, no matter whether current QEMU/kernel
supports them. If the specified GIC version/type is not supported, the
user will get an ambiguous "QEMU boot failure" error when trying to start
the VM. This is not user-friendly.
With this patch, libvirt should be able to query which type (and which
version) of GIC device is supported. Using this information, libvirt
can warn the user during configuration of guests when specified GIC
device type is not supported. Or better, we can just list those versions
that we support, and filter out the unsupported ones.
For example, if we got the query result:
{"return": [{"emulated": false, "version": 3, "kernel": true},
{"emulated": true, "version": 2, "kernel": false}]}
then it means that we support emulated GIC version 2 using:
qemu-system-aarch64 -M virt,accel=tcg,gic-version=2 ...
or KVM-accelerated GIC version 3 using:
qemu-system-aarch64 -M virt,accel=kvm,gic-version=3 ...
If we specify other explicit GIC versions rather than the above, QEMU
will not be able to boot.
The community is working on a more generic way to query these kinds of
information about valid values of machine properties. However, due to
the importance of supporting this specific use case, weecided to first
implement this ad-hoc one; then when the generic method is ready, we
can move on to that one smoothly.

This patch replaces get_ticks_per_sec() calls with the macro
NANOSECONDS_PER_SECOND. Also, as there are no callers, get_ticks_per_sec()
is then removed. This replacement improves the readability and
understandability of code.
For example,
timer_mod(fdctrl->result_timer,
qemu_clock_get_ns(QEMU_CLOCK_VIRTUAL) + (get_ticks_per_sec() / 50));
NANOSECONDS_PER_SECOND makes it obvious that qemu_clock_get_ns
matches the unit of the expression on the right side of the plus.
