36496d50b7 PR/17643: Jared D. McNeill: ktrace leaves ktrace.out file with a kernel 
that does not support ktrace.

d4ddc11a83 Two tweaks: 
- For cleaner subprocess traces, malloc something before
spawning, so the syscalls malloc does while initializing don't gunk up
the trace.
	- Increase pipe buffer sizes.

0af9894f2f [ktruss] Use fork(2), not vfork(2). 
The child process of do_ktrace() does return and the stack is
changed by another function call (execvp()).
By using vfork() (my previous change), the execution of the parent
process resumes on the modified stack.  Oops.
We could use vfork() carefully, but for now use fork().

Problem reported and investigated by Ethan Solomita <ethan@geocast.com>.
Thanks.

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.

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.

4191a1e6d4 - remove duplicated setting for LDSTATIC in ktruss/Makefile. 
- fix command name in SYNOPSIS section of man page.
- link ktrace man page to ktruss man page.
- add executable and man page for ktruss in distrib sets.

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
