9e92c8d486 When opening a trace file, open O_NONBLOCK so that ktrace doesn't stall 
if the target is a fifo.  After opening a trace file, check that it is a
regular file, and if not, return an error.

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.

ktrace was not built into the kernel and prevent ktrace to core dump
somewhere.
