Instead of relying on the mapped address of the MV64361 registers
access them via their memory region. This is not a problem at reset
time when these registers are mapped at the default address but the
guest could change this later and then the RTAS calls accessing PCI
config registers could fail. None of the guests actually do this so
this only avoids a theoretical problem not seen in practice.

qdev_device_add() to check a specific option of the failover device,
"failover_pair_id", before calling the generic mechanism.
It's not needed (and not generic) to do that in qdev_device_add() because
this is also checked by the failover_hide_primary_device() function that

The hide_device helper can be called several times for the same
devices as it shouldn't change any state and should only return an
information.
But not to rely anymore on QemuOpts we have introduced a new field
to store the parameters of the device and don't allow to update it
once it is done.
And as the function is called several times, we ends with:
warning: Cannot attach more than one primary device to 'virtio0'
That is not only a warning as it prevents to hide the device and breaks
failover.
Fix that by checking the device id.
Now, we fail only if the virtio-net device is really used by two different
devices, for instance:
-device virtio-net-pci,id=virtio0,failover=on,... \
-device vfio-pci,id=hostdev0,failover_pair_id=virtio0,... \
-device e1000e,id=e1000e0,failover_pair_id=virtio0,... \
will exit with:
Cannot attach more than one primary device to 'virtio0': 'hostdev0' and 'e1000e0'

QDicts are both what QMP natively uses and what the keyval parser
produces. Going through QemuOpts isn't useful for either one, so switch
the main device creation function to QDicts. By sharing more code with
the -object/object-add code path, we can even reduce the code size a
bit.
This commit doesn't remove the detour through QemuOpts from any code
path yet, but it allows the following commits to do so.

Instead of accessing the global QemuOptsList, which really belong to the
command line parser and shouldn't be accessed from devices, store a
pointer to the QemuOpts in a new VirtIONet field.
This is not the final state, but just an intermediate step to get rid of
QemuOpts in devices. It will later be replaced with an options QDict.
Before this patch, two "primary" devices could be hidden for the same
standby device, but only one of them would actually be enabled and the
other one would be kept hidden forever, so this doesn't make sense.
After this patch, configuring a second primary device is an error.

hide_device() is used for virtio-net failover, where the standby virtio
device delays creation of the primary device. It only makes sense to
have a single primary device for each standby device. Adding a second
one should result in an error instead of hiding it and never using it
afterwards.
Prepare for this by adding an Error parameter to the hide_device()
callback where virtio-net is informed about adding a primary device.

qdev_set_id() is mostly used when the user adds a device (using
-device cli option or device_add qmp command). This commit adds
an error parameter to handle the case where the given id is
already taken.
Also document the function and add a return value in order to
be able to capture success/failure: the function now returns the
id in case of success, or NULL in case of failure.
The commit modifies the 2 calling places (qdev-monitor and
xen-legacy-backend) to add the error object parameter.
Note that the id is, right now, guaranteed to be unique because
all ids came from the "device" QemuOptsList where the id is used
as key. This addition is a preparation for a future commit which
will relax the uniqueness.

DeviceState.id is a pointer to a string that is stored in the QemuOpts
object DeviceState.opts and freed together with it. We want to create
devices without going through QemuOpts in the future, so make this a
separately allocated string.

Some network backends (vhost-user and vhost-vdpa) work only with
specific devices. At startup, they second guess what the command line
option handling will do and error out if they think a non-virtio device
will attach to them.
This second guessing is not only ugly, it can lead to wrong error
messages ('-device floppy,netdev=foo' should complain about an unknown
property, not about the wrong kind of network device being attached) and
completely ignores hotplugging.
Add a callback where backends can check compatibility with a device when
it actually tries to attach, even on hotplug.
