Changpeng Liu da231290b2 lib/vfu_tgt: add library for PCI device emulation 
Previously SPDK use libvfio-user library to provide emulated NVMe
devices to VM, but it's limited to NVMe device type only.  Here we
add SPDK vfu_target library abstraction based on libvfio-user which
supports more PCI device types.

We will add virtio-blk and virtio-scsi devices emulation based on
vfu_tgt library in following patches, actually this library can
support NVMe emulation too, due to the fact that the NVMe emulation
is already exist, so we will keep the NVMe emulation which based on
libvfio-user directly as it is.
