4066649d5a Backed out the micro-optimization in 1.4. It was to help gcc-2.6.3
on i486's (and probably i386's), but it has had very little effect
since gcc-2.7 or gcc-2.95.  With gcc-3.3, it gave a small
pessimization for at least i386's, athlon-xp's and pentium4's, a
small optimization (I think) for pentium1's, and made no difference
for i386's.  (movzbl is best for all the later processors, and the
micro-optimization was to stop it being used on i486's.)

6875d25465 Back out part 1 of the MCFH that changed $Id$ to $FreeBSD$. We are not
ready for it yet.

1130b656e5 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.

5182dcbec2 Rearrange the inner loop of scanc() to get better code on i*86's
(on an i486, 10 cycles (+ cache misses) instead of 15).  The
change should be a no-op if the compiler is any good.  The best
possible i*86 code for the same algorithm is only 1 more cycle
faster on i486's so I don't want to bother implementing an
assembler version.

scanc() is a bottleneck for OPOST processing.  It is naturally
about 4 times as slow as bcopy() on 32-bit systems.

5edd0e154f <libkern/libkern.h> has moved to <sys/libkern.h> (repository copy).
Since /usr/include/libkern doesn't and shouldn't exist, this is the
least evil way to handle this.
