Making Linux stat() less evil

Hi folks,

I may have mentioned this earlier, but our Linuxolator's stat()
implementation calls kern_openat(), followed by an
translate_fd_major_minor() to perform a device major/minor number
lookup. This is very evil, because it causes random chardevs to be
opened when you run ls -l /dev.

I propose the following patch:

I've copied kern_stat() into the Linuxolator. Not the ideal solution,
but it's better than what we have right now. Comments?
