device_add plugs devices into suitable bus. For "real" buses, that
actually connects the device. For sysbus, the connections need to be
made separately, and device_add can't do that. The device would be
left unconnected, and could not possibly work.
Quite a few, but not all sysbus devices already set
cannot_instantiate_with_device_add_yet in their class init function.
Set it in their abstract base's class init function
sysbus_device_class_init(), and remove the now redundant assignments
from device class init functions.

We use the rom infrastructure to write firmware and/or initial kernel
blobs into guest address space. So we're basically emulating the cache
off phase on very early system bootup.
That phase is usually responsible for clearing the instruction cache for
anything it writes into cachable memory, to ensure that after reboot we
don't happen to execute stale bits from the instruction cache.
So we need to invalidate the icache every time we write a rom into guest
address space. We do not need to do this for every DMA since the guest
expects it has to flush the icache manually in that case.
This fixes random reboot issues on e5500 (booke ppc) for me.

It is currently possible to specify things like:
-device e1000,netdev=foo,vlan=1
With this usage, whichever argument was specified last (vlan or netdev)
overwrites what was previousely set and results in a non-working
configuration. Even worse, when used with multiqueue devices,
it causes a segmentation fault on exit in qemu_free_net_client.
That patch treates the above command line options as invalid and
generates an error at start-up.

The qdev_free() function name is misleading since all the function does
is unlink the device from its parent. The device is not necessarily
freed.
The device will be freed when its QObject refcount reaches zero. It is
usual for the parent (bus) to hold the final reference but there are
cases where something else holds a reference so "free" is a misleading
name.
Call object_unparent(obj) directly instead of having a qdev wrapper
function.

When memory regions overlap, priority can be used to specify
which of them takes priority. By making the priority values signed
rather than unsigned, we make it more convenient to implement
a situation where one "background" region should appear only
where no other region exists: rather than having to explicitly
specify a high priority for all the other regions, we can let them take
the default (zero) priority and specify a negative priority for the
background region.

We set default boot order "cad" in every single machine definition
except "pseries" and "moxiesim", even though very few boards actually
care for boot order, and "cad" makes sense for even fewer.
Machines that care:
* pc and its variants
Accept up to three letters 'a', 'b' (undocumented alias for 'a'),
'c', 'd' and 'n'. Reject all others (fatal with -boot).
* nseries (n800, n810)
Check whether order starts with 'n'. Silently ignored otherwise.
* prep, g3beige, mac99
Extract the first character the machine understands (subset of
'a'..'f'). Silently ignored otherwise.
* spapr
Accept an arbitrary string (vl.c restricts it to contain only
'a'..'p', no duplicates).
* sun4[mdc]
Use the first character. Silently ignored otherwise.
Strip characters these machines ignore from their default boot order.
For all other machines, remove the unused default boot order
alltogether.
Note that my rename of QEMUMachine member boot_order to
default_boot_order and QEMUMachineInitArgs member boot_device to
boot_order has a welcome side effect: it makes every use of boot
orders visible in this patch, for easy review.

ROM files that are put in FW CFG are copied to guest ram, by BIOS, but
they are not backed by RAM so they don't get migrated.
Each time we change two bytes in such a ROM this breaks cross-version
migration: since we can migrate after BIOS has read the first byte but
before it has read the second one, getting an inconsistent state.
Future-proof this by creating, for each such ROM,
an MR serving as the backing store.
This MR is never mapped into guest memory, but it's registered
as RAM so it's migrated with the guest.
Naturally, this only helps for -M 1.7 and up, older machine types
will still have the cross-version migration bug.
Luckily the race window for the problem to trigger is very small,
which is also likely why we didn't notice the cross-version
migration bug in testing yet.

Since commit 249d41720b (qdev: Prepare
"realized" property) setting realized = true would register the device's
VMStateDescription, but realized = false would not unregister it. Fix that.
Moving the code from unparenting also revealed that we were calling
DeviceClass::init through DeviceClass::realize as interim solution but
DeviceClass::exit still at unparenting time with a realized check.
Make this symmetrical by implementing DeviceClass::unrealize to call it,
while we're setting realized = false in the unparenting path.
The only other unrealize user is mac_nvram, which can safely override it.
Thus, mark DeviceClass::exit as obsolete, new devices should implement
DeviceClass::unrealize instead.
