There is no need for ioport access for applications that won't use virtio pmds.
Make rte_eal_iopl_init() non-static so that it is called from pmds that need it.

virtio_net_hdr_mem member within virtqueue structure stores a
physical address and is defined as void ptr. When 32bit pmd is used
with 64bit kernel this leads to truncation of 64bit physical address
and pkt i/o does not work.
Changed virtio_net_hdr_mem to phys_addr_t type and
removed the typecasts

This patch supports multiple queues feature in DPDK based virtio-net frontend.
It firstly gets max queue number of virtio-net from virtio PCI configuration and
then send command to negotiate the queue number with backend; When receiving and
transmitting packets, it negotiates multiple virtio-net queues which serve RX/TX;
To utilize this feature, the backend also need support multiple queues feature
and enable it.

Convert the virtio pmd driver to use the PMD_REGISTER_DRIVER macro.
This means that the test applications now have no reference to the virtio library
when building DSO's and must specify its use on the command line with the -d
option. Static linking will still initalize the driver automatically.

Since commit 10ed994 (pci: use igb_uio mapping only when needed),
the flag RTE_PCI_DRV_NEED_IGB_UIO must be set even if RTE_EAL_UNBIND_PORTS
is disabled.
It was not the case for virtio_uio and vmxnet3_uio so the uio resources were
not mapped when RTE_EAL_UNBIND_PORTS was not defined.
Specifically, pci_uio_map_resource() was not called so
pci_dev->mem_resource was not mapped.
