  virtio: introduce vector to virtqueues mapping

Currently we will try to traverse all virtqueues to find a subset that
using a specific vector. This is sub optimal when we will support
hundreds or even thousands of virtqueues. So this patch introduces a
method which could be used by transport to get all virtqueues that
using a same vector. This is done through QLISTs and the number of
QLISTs was queried through a transport specific method. When guest
setting vectors, the virtqueue will be linked and helpers for traverse
the list was also introduced.

The first user will be virtio pci which will use this to speed up
MSI-X masking and unmasking handling.

  virtio-pci: speedup MSI-X masking and unmasking

This patch tries to speed up the MSI-X masking and unmasking through
the mapping between vector and queues. With this patch it will there's
no need to go through all possible virtqueues, which may help to
reduce the time spent when doing MSI-X masking/unmasking a single
vector when more than hundreds or even thousands of virtqueues were
supported.

Tested with 80 queue pairs virito-net-pci by changing the smp affinity
in the background and doing netperf in the same time:

Before the patch:
5711.70 Gbits/sec
After the patch:
6830.98 Gbits/sec

About 19.6% improvements in throughput.

  pci: remove hard-coded bar size in msix_init_exclusive_bar()

This patch lets msix_init_exclusive_bar() can calculate the bar and
pba size based on the number of MSI-X vectors other than using a
hard-coded limit 4096. This is needed to allow device to have more
than 128 MSI_X vectors. To keep migration compatibility, keep using
4096 as bar size and 2048 for pba offset.

Notes: We don't care about the case that using vectors > 128 for
legacy machine type. Since we limit the queue max to 64, so vectors >=
65 is meaningless.

Virtio device will be the first user for this.

  pci: Merge pci_nic_init() into pci_nic_init_nofail()

The error reporting in pci_nic_init() is quite erratic: Some errors
are printed directly with error_report(), and some are passed back
to the caller pci_nic_init_nofail() via an Error pointer.
Since pci_nic_init() is only used by pci_nic_init_nofail(), the
functions can be simply merged to clean up this inconsistency.

  virtio-net: Move DEFINE_VIRTIO_NET_FEATURES to virtio-net

So far virtio-net-device can't expose host features to guest while
using virtio-mmio because it doesn't set DEFINE_VIRTIO_NET_FEATURES on
backend or transport. So the performance is low.

The host features belong to the backend while virtio-net-pci,
virtio-net-s390 and virtio-net-ccw set the DEFINE_VIRTIO_NET_FEATURES
on transports. But they already have the ability to forward property
accesses to the backend child. So if we move the host features to
backends, it doesn't break the backwards compatibility for them and
make host features work while using virtio-mmio.

Here we move DEFINE_VIRTIO_NET_FEATURES to the backend virtio-net. The
transports just sync the host features from backend. Meanwhile move
virtio_net_set_config_size to virtio-net to make sure the config size
is correct and don't expose it.

two conflicting patches is to empty the property arrays
completely, the conflict resolution is to remove them entirely.]
