Update to 20021113, a maintenance release.

portupgrade(1):
- Check return status of hardly failing commands also.

pkgdb(1):
- Add -Q/--quiet and -QQ for internal use.

portsclean(1):
- Ditto.

overall:
- Reduce /bin/sh process calls by replacing shell redirection to
  /dev/null with pkgdb -Q/portsclean -Q/fetch -q. (I know I can do
  fork, dup and exec if necessary)

- Eliminate zombies during running.  Formerly waitpid's against
  terminated processes are delayed until Ruby gets short of resource
  and thus runs a GC, but now portupgrade(1), pkgdb(1) and
  portsclean(1) explicitly kick a waitpid immediately after each
  popen() is done.
