Use __FBSDID().

Convert all instances of:

#include "quad.h"

to:

#include <libkern/quad.h>

as the former breaks under a kernel build.
This change had already been performed on the files that were used in other
kernel builds, however the PowerPC kernel build seems to require some that
weren't being used.

$Id$ -> $FreeBSD$

Back out part 1 of the MCFH that changed $Id$ to $FreeBSD$. We are not
ready for it yet.

Make the long-awaited change from $Id$ to $FreeBSD$

This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.
