affd0ee004 MFp4: Bugfixes for truss(1):
- Fix logic handling execve().  We will not be able to
   obtain information otherwise.
 - truss coredump [1].
 - truss does not work against itself [2].

70cda62de5 Make use of ptrace(2) instead of procfs in truss(1), eliminating

a233d0a2ec - Add decoding of kse_release, kevent, sigprocmask, unmount, socket, getrusage,
rename, __getcwd, shutdown, getrlimit, setrlimit, _umtx_lock, _umtx_unlock,
  pathconf, truncate, ftruncate, kill

- Decode more arguments of open, mprot, *stat, and fcntl.

- Convert all constant-macro and bitfield decoding to lookup tables; much
  cleaner than previous code.

- Print the timestamp of process exit and signal reception when -d or -D are in
  use

- Try six times with 1/2 second delay to debug the child

12a374aa60 When doing the initial open of the proc via procfs, complain if we are
unable to open the /proc/pid/mem file.  Otherwise doing a truss on
a nonexistant pid makes us return success even though no such process
exists.

4418f4740b 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.)

31b9ca1819 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.

3ca80efd3a 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.

50a2f19faf 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.

f13ddbc865 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 :).

d1f6ae4ce3 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.
