c69d844294 Include <sys/time.h> for the declaration of struct timeval. Do not
depend on namespace pollution in <signal.h>.  (truss shouldn't be
using timevals anyway, since it was implemented long after timevals
were obsoleted by timespecs.)

580e0a2b7a #include <sys/proc.h> where needed (for the stop event definitions) and
reorder includes everywhere to conform to style(9).

893618352c Handle the case where we truss an SUGID program -- in particular, we need
to wake up any processes waiting via PIOCWAIT on process exit, and truss
needs to be more aware that a process may actually disappear while it's
waiting.

1fd98d7d88 Calls one or more of malloc(), warn(), err(), syslog(), execlp() or
execvp() in the child branch of a vfork(). Changed to use fork()
instead.

Some of these (mv, find, apply, xargs) might benefit greatly from
being rewritten to use vfork() properly.

3cf51049e0 Sort Xrefs. Use err(3). Remove uneeded #include.
Correct usage: one of {-p pid, command} is required.
Open output file when command line is fully analyzed: incorrect `truss -o f'
command does not create an empty file anymore.

09d64da3a4 Add some copyright and license terms, at Jordan's request. Note that
syscall.h just refers to another file for the copyright notice.

d7b7dcba41 Change the ioctls for procfs around a bit; in particular, whever possible,
change from

	ioctl(fd, PIOC<foo>, &i);

to

	ioctl(fd, PIOC<foo>, i);

This is going from the _IOW to _IO ioctl macro.  The kernel, procctl, and
truss must be in synch for it all to work (not doing so will get errors about
inappropriate ioctl's, fortunately).  Hopefully I didn't forget anything :).

20fa828fac Use the new PF_LINGER flag -- when this is set in a process' proc structure,
said process will not have its event mask cleared (and be restarted) on
the last close of a procfs/mem file for that pid.  This reduces the chance
that a truss-monitored process will be left hanging with these bits set
and nobody looking for it.

This is the least-tested change of all of these, I'm afraid.

fe41f30547 Set the close-on-exec flag in the child; otherwise, it eats up a
