Add fcntl(2).

I initially used overloading, but that actually decreases safety in practice
because which overload you need is (uniquely) determined by the specific
command you're issuing. Forcing callers to explicitly state what they're
doing works around this. As it was, I had to use strace(1) to find my bug.
