It used to be called strtouq on some really old platforms, but we already
have code to deal with that naming.

I checked my pet dinosaur HPUX box, and it has HAVE_LONG_LONG_INT64 but
not HAVE_STRTOULL. It's very possibly the last such animal in captivity
though. I'm not really sure it's worth carrying a port file just to keep
that platform alive.

Another issue is that strtoull() is not necessarily what we want anyway:
what we want is the function corresponding to uint64, which on most
modern platforms is going to be strtoul().
