Use --with-utempter to enable utempter support. The libutempter calls
/usr/libexec/utempter/utempter suid helper to update utmp and wtmp
files.

The patch also removes unnecessary detection of child process
existence (by kill()). This code was replaces with SIGCHLD
hold/release around fork().
Based on the patch from therealneworld@gmail.com.

script currently flushed the input buffer when starting up. This undocumented
behaviour prevents typeahead when starting up (e.g. as part of .profile).
Rather retain queued input. Don't discard queued output either.

This reverts commit 7baec9a5612358559d1556113657223a64e373d1.
Note, scriptreplay(8) expects the "Script started on.." line. We cannot remove
this message...

The "doinput" process doesn't make a difference between SIGWINCH and
SIGCHILD. This process also sends unnecessary SIGWINCH to child (the
signal is ignored by child). Fixed.

script(1) uses three processes (doinput, dooutput and doshell). It's
possible that the shell process is finished before the input and
output processes are completely initialized. For example:
$ script -c "printf Bingo"
In particular case the output and input processes read/write data from
shell process in time when the shell process is already done -- so it
hangs on read().
The second problem is that the output process can finish although
there are unread data from finished shell process -- an output in
the typescript file and on terminal is incomplete!
script(1) has to pass:
$ for i in `seq 1 1000`; do script -q -c "printf 'Bingo\n'"; done | grep -c Bingo
1000
without problems.

script(1) is not consistent and writes "Script started on.." to
scriptfile, although the others messages are ignored when running
with '-q'.
