Jérôme Duval a9c09fcaae POSIX: lseek: support SEEK_DATA and SEEK_HOLE constants
this is queued for issue 8: https://www.austingroupbugs.net/view.php?id=415
this implementation calls the ioctl hook of the filesystem with BSD-like constants
FIOSEEKDATA and FIOSEEKHOLE. if the hook doesn't know the constants, we use the stat size
to return the last hole (as proposed in the draft spec).
