This patchset adds support for using VFIO instead of IGB_UIO to
map the device BARs.

VFIO is a kernel 3.6+ driver allowing secure DMA from userspace
by means of using IOMMU instead of working directly with physical
memory like igb_uio does.

Short summary:
* Adding support for VFIO in EAL PCI code
* Adding new command-line parameter for VFIO interrupt type
* Adding support for VFIO in setup.sh
* Renaming igb_uio_bind to dpdk_nic_bind and adding support for
  VFIO there
* Removing PCI ID list from igb_uio, effectively making it another
  generic PCI driver similar to pci_stub, vfio-pci et al
* Adding autotest for VFIO interrupt types
* Making igb_uio and VFIO compilation optional

I'm submitting this as an RFC because this patch is based off
current dpdk.org branch with David Marchand's RTE_EAL_UNBIND_PORTS
patchset. IOW, this will *not* apply to the dpdk.org tree *unless* you
also apply David's patches beforehand.

In order to make the code a bit more clean while using multiple
drivers, IGB_UIO mapping has been separated into its own file.
