The arguments of error_report() should yield a short error string
without newlines.
A few places try to print additional help after the error message by
embedding newlines in the error string. That's nice, but let's do it
the right way.
Since I'm touching these lines anyway, drop a stray preposition and
some tabs. We don't use tabs for similar messages elsewhere.

Currently, the config size for virtio devices is hard coded. When a new
feature is added that changes the config size, drivers that assume a static
config size will break. For purposes of backward compatibility, there needs
to be a way to inform drivers of the config size needed to accommodate the
set of features enabled.

Fixes a couple of regression bugs introduced by
b9d03e352cb6b31a66545763f6a1e20c9abf0c2c and related to
auto-negotiation:
- Auto-negotiation currently sets link up even if it was
forced down from the monitor.
- If Auto-negotiation was in progress during migration,
link will never come up.
As a fix, don't touch NC link_down field at all,
instead add code on receive path to check
guest link status.

b0b873a07872f7ab7f66f259c73fb9dd42aa66a9 bumped the vmstate version and
introduced an old-style load function to handle migration from prior
(<= 1.2) versions.
The load function passes the top-level PIIX4PMState pointer to
vmstate_load_state() to handle nested structs for APMState and
pci_status, which leads to corruption of the top-level PIIX4PMState,
since pointers to the nested structs are expected.
A segfault can be fairly reliably triggered by migrating from 1.2 and
issuing a reset, which will trigger a number of QOM operations which
rely on the now corrupted ObjectClass/Object members.
Fix this by passing in the expected pointers for vmstate_load_state().

qdev_free and qbus_free have to do unparent+unref, because nobody else
drops the initial reference (the one included by object_initialize)
before them.
For device_init_func and do_device_add, this is trivially correct,
since the DeviceState goes out of scope.
For qdev_create, qdev_try_create and qbus_init, it is a bit more tricky.
What we are doing here is just assuming that the caller knows what it's
doing, and won't call qdev_free/qbus_free while the device is still there.
This is a pretty reasonable assumption and (behind the scenes) is also
what GObject/GTK does. GTK actually has a "floating reference" that
goes away as soon as the caller does gtk_container_add or something
like that, but in the end qbus_init and qdev_try_create are already
adding the new object to its qdev parent! So in the end the two solutions
are the same.

Similarly, a bus holds a reference back to the device, and this will
prevent the device from going away as soon as this reference is counted
properly. To avoid this, move the unrealization of devices to the
unparent callback. This includes recursively unparenting all the buses
and (after the previous patch) the devices on those buses, which ensures
that the web of references completely disappears for all devices that
reside (in the qdev tree) below the one being unplugged.
After this patch, the qdev tree and the bus<->child relationship is
defined as "A is above B, iff unplugging A will automatically unplug B".

This patch lets vhost support multiqueue. The idea is simple, just launching
multiple threads of vhost and let each of vhost thread processing a subset of
the virtqueues of the device. After this change each emulated device can have
multiple vhost threads as its backend.
To do this, a virtqueue index were introduced to record to first virtqueue that
will be handled by this vhost_net device. Based on this and nvqs, vhost could
calculate its relative index to setup vhost_net device.
Since we may have many vhost/net devices for a virtio-net device. The setting of
guest notifiers were moved out of the starting/stopping of a specific vhost
thread. The vhost_net_{start|stop}() were renamed to
vhost_net_{start|stop}_one(), and a new vhost_net_{start|stop}() were introduced
to configure the guest notifiers and start/stop all vhost/vhost_net devices.

This patch adds basic multiqueue support for qemu. The idea is simple, an array
of NetClientStates were introduced in NICState, parse_netdev() were extended to
find and match all NetClientStates belongs to the backend and place their
pointers in NICConf. Then qemu_new_nic can setup a N:N mapping between NICStates
that belongs to a nic and NICStates belongs to the netdev. And a queue_index
were introduced in NetClientState to track its index. After this, each peers of
a NICState were abstracted as a queue.
After this change, all NetClientState that belongs to the same backend/nic has
the same id. When use want to change the link status, all NetClientStates that
belongs to the same backend/nic will be also changed. When user want to delete
a device or netdev, all NetClientStates that belongs to the same backend/nic
will be deleted also. Changing or deleting an specific queue is not allowed.

This reverts commit 84dd2120247a7d25ff1bb337de21c0e76816ad2d.
I'm not sure what issue the original commit was meant to fix, or if
the logic is actually wrong, but it causes e1000 to stop working
after a guest issues a reset.
>From what I can tell a guest with an e1000 nic has no way of changing
the link status, as far as it's NetClient peer is concerned, except
in the auto-negotiation path, so with this patch in place there's no
recovery after a reset, since the link goes down and stays that way.
Revert this patch now to fix the bigger problem, and handle any
lingering issues with a follow-up.
Reproduced/tested with qemu-jeos and Ubuntu 12.10.

Despite cautioning that S390CPU is needed for upcoming CPUState
refactorings, commit 5d69c547d947798cba92d836d06f6e017ba2b19d (s390:
I/O interrupt and machine check injection.) added functions
cpu_inject_io() and cpu_inject_crw_mchk() with CPUS390XState argument,
claiming consistency with cpu_inject_ext().
This complicates making cpu_interrupt() take a CPUState even more and it
required to pass &cpu->env from some S390CPU-aware call sites already,
creating inconsistency elsewhere. Address that.
This also eliminates the need for CPUS390XState in s390_virtio_irq().
