If a management application (like Libvirt) want's to preserve
migration ability and switch to '-machine memory-backend' it
needs to set exactly the same RAM id as QEMU would. Since the id
is machine type dependant, expose it under 'query-machines'
result. Some machine types don't have the attribute set (riscv
family for example), therefore the QMP attribute must be
optional.

object_get_canonical_path_component() returns a malloced copy of a
property name on success, null on failure.
19 of its 25 callers immediately free the returned copy.
Change object_get_canonical_path_component() to return the property
name directly. Since modifying the name would be wrong, adjust the
return type to const char *.
Drop the free from the 19 callers become simpler, add the g_strdup()
to the other six.

qom/object.c provides object_property_get_TYPE() and
object_property_set_TYPE() for a number of common types. These are
all convenience wrappers around object_property_get_qobject() and
object_property_set_qobject().
Except for object_property_get_uint16List(), which is unusual in two ways:
* It bypasses object_property_get_qobject(). Fixable; the previous
commit did it for object_property_get_enum())
* It stores the value through a parameter. Its contract claims it
returns the value, like the other functions do. Also fixable.
Fixing is not worthwhile, though: object_property_get_uint16List() has
seen exactly one user in six years.
Convert the lone user to do its job with the generic
object_property_get_qobject(), and drop object_property_get_uint16List().

When user doesn't request any explicit CPU model with libvirt or QEMU,
a machine type specific CPU model is picked. Currently there is no way
to determine what this QEMU built-in default is, so libvirt cannot
report this back to the user in the XML config.
This extends the "query-machines" QMP command so that it reports the
default CPU model typename for each machine.

Move query-target and its return type TargetInfo from misc.json to
machine.json, where they are covered by MAINTAINERS section "Machine
core". Also move its implementation from arch_init.c to
hw/core/machine-qmp-cmds, where it is likewise covered.
All users of SysEmuTarget are now in machine.json. Move it there from
common.json.

sysemu/sysemu.h is a rather unfocused dumping ground for stuff related
to the system-emulator. Evidence:
* It's included widely: in my "build everything" tree, changing
sysemu/sysemu.h still triggers a recompile of some 1100 out of 6600
objects (not counting tests and objects that don't depend on
qemu/osdep.h, down from 5400 due to the previous two commits).
* It pulls in more than a dozen additional headers.
Split stuff related to run state management into its own header
sysemu/runstate.h.
Touching sysemu/sysemu.h now recompiles some 850 objects. qemu/uuid.h
also drops from 1100 to 850, and qapi/qapi-types-run-state.h from 4400
to 4200. Touching new sysemu/runstate.h recompiles some 500 objects.
Since I'm touching MAINTAINERS to add sysemu/runstate.h anyway, also
add qemu/main-loop.h.

[Unbreak OS-X build]

In my "build everything" tree, changing qemu/main-loop.h triggers a
recompile of some 5600 out of 6600 objects (not counting tests and
objects that don't depend on qemu/osdep.h). It includes block/aio.h,
which in turn includes qemu/event_notifier.h, qemu/notify.h,
qemu/processor.h, qemu/qsp.h, qemu/queue.h, qemu/thread-posix.h,
qemu/thread.h, qemu/timer.h, and a few more.
Include qemu/main-loop.h only where it's needed. Touching it now
recompiles only some 1700 objects. For block/aio.h and
qemu/event_notifier.h, these numbers drop from 5600 to 2800. For the
others, they shrink only slightly.

Export machine type deprecation status through the query-machines
QMP command. With this, libvirt and management software will be
able to show this information to users and/or suggest changes to
VM configuration to avoid deprecated machines.

Legacy '-numa node,mem' option has a number of issues and mgmt often
defaults to it. Unfortunately it's no possible to replace it with
an alternative '-numa memdev' without breaking migration compatibility.
What's possible though is to deprecate it, keeping option working with
old machine types only.
In order to help users to find out if being deprecated CLI option
'-numa node,mem' is still supported by particular machine type, add new
"numa-mem-supported" property to output of query-machines.
"numa-mem-supported" is set to 'true' for machines that currently support
NUMA, but it will be flipped to 'false' later on, once deprecation period
expires and kept 'true' only for old machine types that used to support
the legacy option so it won't break existing configuration that are using
it.

To get rid of the global smp_* variables we're currently using, it's recommended
to pass MachineState in the list of incoming parameters for functions that use
global smp variables, thus some redundant parameters are dropped. It's applied
for legacy smbios_*(), *_machine_reset(), hot_add_cpu() and mips *_create_cpu().

The handlers for qapi/machine.json's QMP commands are spread over
cpus.c, hw/core/numa.c, monitor/misc.c, monitor/qmp-cmds.c, and vl.c.
Move them all to new hw/core/machine-qmp-cmds.c, where they are
covered by MAINTAINERS section "Machine core", just like
qapi/machine.json.
