Deprecating calls to not-thread safe asctime(), ctime(), and localtime()
calls is pretty close to pointless change. Lets do it to reduce lgtm scan
warnings with justification it's nicer to use static analysis tools when
they have very few positives.

Change a HYPHEN-MINUS (code 0x55, 2D) to a minus (\-), if in front of
1) a name of an option
2) a negative number to be printed.
See man-pages(7) [Debian package "manpages"].
The output from "nroff" is unchanged.

Add a comma (,) after "e.g." and "i.e.", or use English words
(man-pages(7) [package "manpages"]).
Abbreviation points should be protected (usually with the
non-printing, zero width character '\&') from being interpreted as an
end of sentence, if they are not, and that independent of their current
place on the line.
This is important when typing, as one does not usually know in
advance when the editor jumps to a new line.

Two-fonts macros are made for two or more arguments.
Remove space at end of lines in the files "term-utils/{script.1,
scriptlive.1, scriptreplay.1}".
Put "\-\-summary" to the correct indent in the file
"term-utils/script.1"

If agetty is compiled without support for ISSUEDIR, then it implements
a stub for `issuedir_read` that simply does nothing. In fact it does
too little, as it doesn't have a proper return statement even though the
function returns an integer.
Fix the issue by always returning `1` from `issuedir_read`. This
is the same error code that the real implementation of that function
returns in case it cannot open the directory and is thus a sensible
default to pretend that the directory doesn't exist.

It some cases it makes sense to disable ECHO flag also when script
used in pipe. This new option allows to keep full control in user's
hands.

We need a proper way how to inform child (shell) that the game is
over. It seems the best is to send EOF to child rather than
immediately break PTY mainloop where we have poll(), because shell can
still produce data etc.

For tools like su(1) is ECHO flag unexpected for use-case like
echo 'date' | su - user
but script(1) need the echo to keep input recorded.
The patch also return execlp() use to script(1) code.

Let's make life easier for admins and allow to review issue file
output on the current terminal without all full agetty execution. Use
case is pretty simple:
# $EDITOR /etc/issue
# agetty --show-issue

It's necessary to create signal-fd before fork() to get SIGCHLD,
because child could be faster than our code.

ul_pty code is able to do all necessary things for us, so don't waste
effort and keep the child variable in main() only.

Now the code is duplicate on many places, but all we usually need is to
remember child status. It seems good enough to have very simple
callback child_die() to inform application about a change.
The patch also add PID to all signal related callbacks.

This patch consolidate pseudo-terminal stuff in util-linux. From now
there is only one implementation used in su(1) --pty, scriptlive(1)
and script(1).
The new stuff is based on the original script(1) -- it means poll()
and signalfd() based.
Note that script(1) code does not provide fallback for systems/libc
where is no openpty().

Add alias to -t,--timing to make it easy to copy and past script(1)
comnand line to scriptlive(1) and scriptreplay(1) command lines.
For example:
record:
$ script --log-timing tm --log-in in
print:
$ scriptreplay --log-timing tm --log-in in
re-run:
$ scriptlive --log-timing tm --log-in in
And command line is still the same.

After this change shell executed by scriptlive(1) is going to behave
like shell in script(1). It means that the shell stdin is a
pseudo-terminal rather than pipe. This allows live replay of
interactive applications, ssh sessions, etc.

The new header/info lines in log uses 0, but it's unexpected by
scriptreplay as there was always number formatted by %f.

The old good scriptreplay(1) just display your recorded session, the
scriptlive(1) uses stdin typescript (from new script(1)) to execute
your commands again.
