This patch changes st_mtime/atime/ctime to use floats
if the system offers the st.st_mtim.tv_nsec field and
if that field is nonzero. Support for other APIs can be
added as they come available (on Windows, I believe
you'll have to sidestep the C library to get FILETIMEs).

While this is an API change, reports indicate that
Python applications deal fine with getting floats from
stat.

Hm, I didn't read the patch carefully enough. I'd prefer it
of the values were *always* floats. This avoids portability
problems where someone tests their code on a system where
they happen to be ints, and then the code is ported to a
system that has floats.

Same as with time.time(): this always returns a float, even
if the resolution is only seconds.

Correct in posixmodule.c 1.255, libos.tex 2.255.
