This adds support for hiding a device to the qbus and qdev APIs. The
first user of this will be the virtio-net failover feature but the API
introduced with this patch could be used to implement other features as
well, for example hiding pci devices when a pci bus is powered off.
qdev_device_add() is modified to check for a failover_pair_id
argument in the option string. A DeviceListener callback
should_be_hidden() is added. It can be used by a standby device to
inform qdev that this device should not be added now. The standby device
handler can store the device options to plug the device in at a later
point in time.
One reason for hiding the device is that we don't want to expose both
devices to the guest kernel until the respective virtio feature bit
VIRTIO_NET_F_STANDBY was negotiated and we know that the devices will be
handled correctly by the guest.
More information on the kernel feature this is using:
https://www.kernel.org/doc/html/latest/networking/net_failover.html
An example where the primary device is a vfio-pci device and the standby
device is a virtio-net device:
A device is hidden when it has an "failover_pair_id" option, e.g.
-device virtio-net-pci,...,failover=on,...
-device vfio-pci,...,failover_pair_id=net1,...

Trying to reboot a VM while a migration is running can
move to the prelaunch state (because of the reset) while
the runstate is in finish migrate state.
As the logical step after the finish migrate is postmigrate,
this can create an invalid state transition from prelaunch state
to postmigrate state and this raises an error and aborts:
invalid runstate transition: 'prelaunch' -> 'postmigrate'
As we are not able to manage reset in finish migrate state the
best we can do is to ignore any changes and delay them until
the next state which should be postmigrate and which should allow
this kind of transition.

'warn' (default): Only log an error message (once) on host if more than one
device is shared by same export, except of that just ignore this config
error though. This is the default behaviour for not breaking existing
installations implying that they really know what they are doing.
'forbid': Like 'warn', but except of just logging an error this
also denies access of guest to additional devices.
'remap': Allows to share more than one device per export by remapping
inodes from host to guest appropriately. To support multiple devices on the
9p share, and avoid qid path collisions we take the device id as input to
generate a unique QID path. The lowest 48 bits of the path will be set
equal to the file inode, and the top bits will be uniquely assigned based
on the top 16 bits of the inode and the device id.

Everybody who used something like "-machine accel=kvm:tcg" in the past
might be tempted to specify a similar list with the -accel parameter,
too, for example "-accel kvm:tcg". However, this is not how this
options is thought to be used, since each "-accel" should only take care
of one specific accelerator.
In the long run, we really should rework the "-accel" code completely,
so that it does not set "-machine accel=..." anymore internally, but
is completely independent from "-machine". For the short run, let's
make sure that users cannot use "-accel xyz:tcg", so that we avoid
that we have to deal with such cases in the wild later.

Waking from suspend is not logically a machine reset on all machines,
particularly in the paravirtualized case rather than hardware
emulated. The ppc spapr machine for example just invokes hypervisor
to suspend, and expects that call to return with the machine in the
same state (modulo some possible migration and reconfiguration
details).
Implement a machine ->wakeup method and use that if it exists.

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.

bdrv_drain_all(); this nested bdrv_drain_all() will thus be a no-op,

When we redirect output to a file, the message "char device redirected

The generic smp_parse() code in vl.c is moved to hw/core/machine.c, and
become the default implementation of MachineClass::smp_parse. A PC-specific
function called pc_smp_parse() has been added to hw/i386/pc.c, which in
this patch changes nothing against the default one .

Form this commit, the smp_cpus/smp_cores/smp_threads/max_cpus are deprecated
and only machine properties within MachineState are fully applied and enabled.

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 cpu topology property CpuTopology is added to the MachineState
and its members are initialized with the leagcy global smp variables.
From this commit, the code in the system emulation mode is supposed to
use cpu topology variables from MachineState instead of the global ones
defined in vl.c and there is no semantic change.

Most callers know which monitor type they want to have. Instead of
calling monitor_init() with flags that can describe both types of

qemu-system-FOO's main() acts on command line arguments in its own
idiosyncratic order. There's not much method to its madness.
Whenever we find a case where one kind of command line argument needs
to refer to something created for another kind later, we rejigger the
order.
Recent commit cda4aa9a5a "vl: Create block backends before setting
machine properties" was such a rejigger. Block backends are now
created before "delayed" objects. This broke persistent reservation
management. Reproducer:
$ qemu-system-x86_64 -object pr-manager-helper,id=pr-helper0,path=/tmp/pr-helper0.sock-drive -drive file=/dev/mapper/crypt,file.pr-manager=pr-helper0,format=raw,if=none,id=drive-scsi0-0-0-2
qemu-system-x86_64: -drive file=/dev/mapper/crypt,file.pr-manager=pr-helper0,format=raw,if=none,id=drive-scsi0-0-0-2: No persistent reservation manager with id 'pr-helper0'
The delayed pr-manager-helper object is created too late for use by
-drive or -blockdev. Normal objects are still created in time.
pr-manager-helper has always been a delayed object (commit 7c9e527659
"scsi, file-posix: add support for persistent reservation
management"). Turns out there's no real reason for that. Make it a
normal object.

Currently, -accel help shows all possible accelerators regardless
if they are enabled in the binary or not. That is a different
semantic from -cpu and -machine helps, for example. So this change
makes it to list only the accelerators which support is compiled
in the binary target.
Note that it does not check if the accelerator is enabled in the
host, so the help message's header was rewritten to emphasize
that. Also qtest is not displayed given that it is used for
internal testing purpose only.
