Split out the contents of libvfio.h into separate header files, but keep libvfio.h as the top-level include that all tests can use. Put all new header files into a libvfio/ subdirectory to avoid future name conflicts in include paths when libvfio is used by other selftests like KVM. No functional change intended.
