Stephen Heumann 5c972aa397 Fix our handling of process groups for job control, working around a couple GNO bugs.

*Most significantly, we avoid using setpgid(), because it doesn't work and in fact corrupts the kernel's process group table.
*Also, work around tctpgrp() returning garbage instead of 0 on success.

This adds an implementation of tcsetpgrp that works by reading the process tables to find a process in the appropriate group. This isn't used for the main job control operations, though, since it might be relatively slow.

At this point, basic job control seems to work.

coreutils

In redirection operations, map fds 0/1/2 to 1/2/3 so they work as stdin/stdout/stderr, preserving compatibility with Unix shell scripts.
