Ack. This looks reasonable to me. The only change since then is I
finally went back and changed the default copyright notice for new
auto-generated guts files. :P

Just to be clear, this does *not* handle/support renameat2; it rejects
it with ENOSYS. Actually handling renameat2 correctly requires a change
to the pseudo IPC protocol, because it needs a way to express an atomic
exchange, which requires having two dev/inode pairs in the message.
