itohy 2f4c0d5e74 Make ktrace(1) not affect interactions between processes.
Following examples show the cases.

    % ktrace -f - false >/dev/null && echo wrong
    wrong
    % ktrace -f - -i /usr/sbin/update >/dev/null
    (does not return to command line)

That is, back out last change and restore the roles of parent/child for
ktrace(1).  The ktruss(1) stuff still remains.
Yes, ktruss(1) has the problems.  Better implementation is expected.

darrenr c1f203f8b5 Change behaviour from running the command as the parent and ktrace/ktruss as
the child to be ktruss/ktrace is the parent.  This fixes a problem with ktruss
where the prompt would be returned in the middle of output.

itohy 99624b0b6d Fix fowllowing problems:
1. If fork()ing, the program is executed twice.
2. If the ktruss(1) output is bufferd, the final output is not flushed
   (because it is executing).

    % ktrace -f - rm >/dev/null

of errno.

nathanw 3cc8349a71 Make "ktrace -f" work again. Slightly klugy because of the
#ifdef's for KTRUSS.
