As pci id initialization is moved to common layer,
some initialization function can be empty.
So don't call init method if NULL.

When qemu gets compiled without support of vhost-net, any attempt
to use it fails with a very clear error message:

 qemu-system-x86_64: -netdev ...,vhost=on: vhost-net requested but could not be initialized

there's absolutely no reason given _why_ it coult not be
initialized, and even strace'ing the process in question
does not reveal any errors.  So print a message telling
what's going on.

Older versions of libcurl don't have some of the features we try to
use, in particular curl_multi_setopt(). Check for this in the 'is
libcurl available?' configure test so we disable curl support if the
library is too old.

Pulls in latest version from kernel 3.0-rc2.

Some changes around AER now require local defines as QEMU accesses the
error source identification register via sub-words.

Current vm_running was not explicitly initialized and its value was changed by
vm state notifier, this may confuse the virtio device being hotplugged such as
virtio-net with vhost backend as it may think the vm was not running. Solve this
by initialize this value explicitly in virtio_common_init().

The virtio_queue_notify() function checks that the virtqueue number is
less than the maximum number of virtqueues.  A signed comparison is used
but the virtqueue number could be negative if a buggy or malicious guest
is run.  This results in memory accesses outside of the virtqueue array.

It is risky doing input validation in common code instead of at the
guest<->host boundary.  Note that virtio_queue_set_addr(),
virtio_queue_get_addr(), virtio_queue_get_num(), and many other virtio
functions do *not* validate the virtqueue number argument.

Instead of fixing the comparison in virtio_queue_notify(), move the
comparison to the virtio bindings (just like VIRTIO_PCI_QUEUE_SEL) where
we have a uint32_t value and can avoid ever calling into common virtio
code if the virtqueue number is invalid.
