xen: Fix, no unplug of pt device by platform device.

The Xen platform device will unplug any NICs if requested by the guest (PVonHVM)
including a NIC that would have been passthrough. This patch makes sure that a
passthrough device will not be unplug.

qom: object_delete should unparent the object first

object_deinit is only called when the reference count goes to zero,
and yet tries to do an object_unparent. Now, object_unparent
either does nothing or it will decrease the reference count.
Because we know the reference count is zero, the object_unparent...

pci.c: Add opaque argument to pci_for_each_device.

The purpose is to have a more generic pci_for_each_device by passing an extra
argument to the function called on every device.

This patch will be used in a next patch.

xen: Fix PV-on-HVM

In the context of PV-on-HVM under Xen, the emulated nics are supposed to be
unplug before the guest drivers are initialized, when the guest write to a
specific IO port.

Without this patch, the guest end up with two nics with the same MAC, the...

qdev: qdev_unplug(): use error_set()

It currently uses qerror_report(), but next commit will convert
the drive_del command to the QAPI and this requires using
error_set().

One particularity of qerror_report() is that it knows when it's
running on monitor context or command-line context and prints the...

qom: Unify type registration

Replace device_init() with generalized type_init().

While at it, unify naming convention: type_init([$prefix_]register_types)
Also, type_init() is a function, so add preceding blank line where
necessary and don't put a semicolon after the closing brace....

qdev: register all types natively through QEMU Object Model

This was done in a mostly automated fashion. I did it in three steps and then
rebased it into a single step which avoids repeatedly touching every file in
the tree.

The first step was a sed-based addition of the parent type to the subclass...

block: convert qemu_aio_flush() calls to bdrv_drain_all()

Many places in QEMU call qemu_aio_flush() to complete all pending
asynchronous I/O. Most of these places actually want to drain all block
requests but there is no block layer API to do so.

This patch introduces the bdrv_drain_all() API to wait for requests...

xen-platform: convert to memory API

Since this device bypasses PCI and registers I/O ports directly with
the system bus, it needs further attention.

xen: implement unplug protocol in xen_platform

The unplug protocol is necessary to support PV drivers in the guest: the
drivers expect to be able to "unplug" emulated disks and nics before
initializing the Xen PV interfaces.
It is responsibility of the guest to make sure that the unplug is done...
