Use a pty for prefixed output instead of pipes for stdout/stderr. This

    is so that programs can get information about the controlling terminal.
    This change was triggered by bug #188506 where it's possible that
    stdin, stdout and stderr didn't point to a terminal but ended up on one
    via our pipes. Using a pty means that stdout and stderr always point to
    a terminal, but we lose the ability to tell them apart.
    If there is not a pty available then we use un-prefixed output as normal.
    This change has also introduced the need for a signal pipe so that
    SIGCHLD can exit the loop cleanly.

     libeinfo now works out the number of columns from stdout rather than
