Currently DNS resolution is done automatically as part
of the creation of a QIOChannelSocket object instance.
This works ok for network clients where you just end
up a single network socket, but for servers, the results
of DNS resolution may require creation of multiple
sockets.
Introducing a DNS resolver API allows DNS resolution
to be separated from the socket object creation. This
will make it practical to create multiple QIOChannelSocket
instances for servers.

Now that task objects have a directly associated error,
there's no need for an an Error **errp parameter to
the QIOTask thread worker function. It already has a
QIOTask object, so can directly set the error on it.

Currently the QIOTaskFunc signature takes an Object * for
the source, and an Error * for any error. We also need to
be able to provide a result pointer. Rather than continue
to add parameters to QIOTaskFunc, remove the existing
ones and simply pass the QIOTask object instead. This
has methods to access all the other data items required
in the callback impl.

Currently when a task fails, the error is never explicitly
associated with the task object, it is just passed along
through the completion callback. This adds the ability to
explicitly associate an error with the task.

Currently there is no data associated with a successful

Incrementing the reference in qio_task_get_source is
not necessary, since we're not running concurrently
with any other code touching the QIOTask. This
minimizes chances of further memory leaks.

As noticed by David Gilbert, commit 6053a86 'kvmclock: reduce kvmclock
differences on migration' added 'x-mach-use-reliable-get-clock' and a
compatibility entry that turns it off; however it got merged after 2.8.0
was released but the entry has gone into PC_COMPAT_2_7 where it should
have gone into PC_COMPAT_2_8.
Fix it by moving the entry to PC_COMPAT_2_8.

Add a board level property to the virt board which will
enable EL2 on the CPU if the user asks for it. The
default is not to provide EL2. If EL2 is enabled then
we will use SMC as our PSCI conduit, and report the
virtualization support in the GICv3 device tree node
and the ACPI tables.

If we are giving the guest a CPU with EL2, it is likely to
want to use the HVC instruction itself, for instance for
providing PSCI to inner guest VMs. This makes using HVC
as the PSCI conduit for the outer QEMU a bad idea. We will
want to use SMC instead is this case: this makes sense
because QEMU's PSCI implementation is effectively an
emulation of functionality provided by EL3 firmware.
Add code to support selecting the PSCI conduit to use,
rather than hardcoding use of HVC.

As the first step in adding support for the virtualization
extensions to the GICv3 emulation:
* add the necessary data fields to the state structures
* add the fields to the migration state, as a subsection
which is only present if virtualization is enabled
The use of a subsection means we retain migration
compatibility as EL2 is not enabled on any CPUs currently.

Augment the GIC's QOM device interface by adding two
new sets of sysbus IRQ lines, to signal VIRQ and VFIQ to
each CPU.
We never use these, but it's helpful to keep the v2-and-earlier
GIC's external interface in line with that of the GICv3 to
avoid board code having to add extra code conditional on which
version of the GIC is in use.

The Aspeed SMC controllers have a mode (Command mode) in which
accesses to the flash content are no different than doing MMIOs. The
controller generates all the necessary commands to load (or store)
data in memory.
However, accesses are restricted to the segment window assigned the
the flash module by the controller. This window is defined by the
Segment Address Register.

The SPI controller of the AST2400 SoC has less registers. So we can

When running qemu-system-m68k with the "-net" parameter (for example
simply "-net nic -net user"), there is currently a confusing warning
message saying:
Warning: requested NIC (anonymous, model mcf_fec) was not created
(not supported by this machine?)
This seems to happen because the MCF NIC has never been adapted to
the currently expected QEMU device behavior. Thus let's QOMify the
NIC now to get rid of the warning message.
