   Have __realpath() do the pathname==NULL -> EINVAL check itself, eliminating
   the need to do this in libc.
   btw, it is unfortunate posix went this way, because converting a clearly
   illegal condition to not be fatal but instead return an error which is
   potentially not checked in the caller, is sadly a large component of the
   runaway-train model that makes exploitation of software easy.. illegal
   software should crash hard.
