This whole procedure of "let's copy the file and rip out unneeded stuff
later" looks very ugly to me, especially if I'd come across it in the
future, e.g. during a bisect. This patch only adds a file that is not
compiled, and later changes will be "rip out unwanted stuff from
vfio_pci_common.c" instead of the more positive "move common stuff to
vfio_pci_common.c". I think refactoring/moving interfaces/code that it
makes sense to share makes this more reviewable, both now and in the
future.
