081e5c4890 - 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

0cf21b4f58 Add a -s flag for the same functionality as strace. Introduce a Name
type which is a String type that has no -s limitations applied to it.
Change most Strings in the code to Names and add a few extra syscalls,
namely munmap, read, rename and symlink.  This was enough to facilitate
following file descriptor allocations in the code more easily and
getting a hint at what's being read/written from/to files.  More
syscalls should really be added.

While here, fix an off-by-one bug in the buffer truncation code and
add a fflush so that truss's output reflects the syscall that the
program is stuck in.

2bae4eb308 Support readlink(2) better. Readlink does not nul terminate the
result buffer, so we need to format it ourselves.  The problem is
that the length is stored as the return value from readlink, so we
need to pass the return value from our syscall into print_arg.

Motivated by: truss garbage on my screen from reading /etc/malloc.conf.

e45a5a0d08 Add support for decoding Timespec, Timeval, Itimerval, Pollfd,
Fd_set and Sigaction structures. Use these for printing the arguments
to sigaction(), nanosleep(), select(), poll(), gettimeofday(),
clock_gettime(), recvfrom(), getitimer() and setitimer().

This is based on Dan's patch from the PR but I've hacked it for
style and some other issues. While Dan has checked this patch, any
goofs are probably my fault.

(The PR also contains support for the dual return values of pipe().
These will follow once I've ported that support to platforms other
than i386.)

1bcb5f5a96 Port truss(1) to 64-bit architectures:
o  Syscall return values do not fit in int on 64-bit architectures.
   Change the type of retval in <arch>_syscall_exit() to long and
   change the prototype of said function to return a long as well.
o  Change the prototype of print_syscall_ret() to take a long for
   the return address and change the format string accordingly.
o  Replace the code sequence
	tmp = malloc(X);
	sprintf(tmp, format, ...);
   with X by definition too small on 64-bit platforms by
        asprintf(&tmp, format, ...);

With these changes the output makes sense again, although it does
mess up the tabulation on ia64. Go widescreen...

Not tested on: alpha, sparc64.

9897b20356 Add options to print the argument and environment string parameters to
execve().

This could be done in a more general manner but it still wouldn't
be very pretty.

9ddd141263 Teach truss(1) to display sockaddrs. It currently knows about AF_INET,
AF_INET6 and AF_UNIX sockaddrs, and will recognize accept(), bind(),
connect(), getpeername() and getsockname() as syscalls taking sockaddr
arguments.  Some enterprising soul might want to add (and test) support
for the send() / recv() family of syscalls as well.

970649f9c9 First cut at printing out ioctl names intelligently. Note that this doesn't
handle linux ioctls (yet?).  This uses the mkioctl script from kdump,
bless its little heart.
