* don't initialize timingfd (to stderr) when -t not specified
* care about timingfd dooutput() rather in main()
* make timingdf gloval like fscript FILE
* close all in done()
* close irrelevant things in subshell and input processes

If both -f and -t are given, flush the timing fd on each write, similar
to the behavior on the script fd. This allows playback of still-running
sessions, and reduces the risk of ending up with empty timing files when
script(1) exits abnormally.

Let's use nanosleep() although if usleep() exists. The nanosleep
function does no interact with signals and other timers.
The patch introduces xusleep() as replacement to libc (or our fallback)
usleep(). Yes, we don't want to use struct timespec + nanosleep()
everywhere in code as nano-time resolution is useless for us.
The patch also enlarges delays in some busy wait loops. It seems
enough to try read/write 4x per second.

The current code waits for empty file master and slave descriptors,
but it makes sense only if there is child process that cares (read)
about data in the descriptors.

echo "ps uf" | script
does not work because script assume that stdin is terminal and
it does not forward EOF to the pty.
This patch:
* make non-tty use-case more robust (don't call tty ioclts to
non-tty file descriptors.
* send EOF (CTL('D') control char) to the master channel when
detected eof by read() on stdin
* wait for empty master and slave file descriptors to be sure that
we don't miss date for typescript. This is also necessary to be
sure that slave channel (shell) is completely initialized otherwise
EOF is ignored.

It seems that setterm -dump does not dump terminal attributes, but
the man page says -dump includes the attributes. Let's fix the man

which is due legacy reasons a block terminal of type 3270 or higher.
Whereas the second serial line on a S/390(x) is a real character
terminal which is compatible with VT220.

* it seems that we don't have to link the utils with ncurses, tinfo is enough.
This change saves one unnecessary dependence.
* libtinfo is also distributed with pkg-config files, so we can use
PKG_CHECK_MODULES() as a primary source for LIBS and CFLAGS.
* add TINFO_CFLAGS (although it's probably always empty)

The ncurses package has been providing pkg-config files for a while now.
So let's start using them to get the proper linker & compiler flags. It
can make a difference when ncurses is configured in a way that requires
extra link time flags but util-linux doesn't provide them, or when the
headers live in a weird place and util-linux can't find them.
Since the NCURSES_LIBS is always defined for the Makefile, there's no need
to gate on the HAVE_NCURSES conditional. When it's disabled, the var will
simply be empty.
With a minor tweak to how tinfo is handled, we can do the same thing -- we
just always use TINFO_LIBS in the Makefile's.

The ncurses term.h header has logic in it to detect if nucrses.h has
already been included and void defining things when it has. But since
setterm includes term.h and the ncurses.h, it doesn't work and we can
get fun build-time warnings like:
CC term-utils/setterm-setterm.o
In file included from term-utils/setterm.c:109:0:
/usr/include/ncursesw/ncurses.h:827:12: warning: redundant redeclaration of 'tigetflag' [-Wredundant-decls]

This patch allows to use a new \S or \S{VARNAME} sequence in the
/etc/issue file. The sequence prints data from /etc/os-release. The
reason is to keep /etc/issue file distribution and release
independent.
The \S{ANSI_COLOR} is converted to the real terminal escape seq.
For example:
\S
Kernel \r on an \m (\l)
or more complex example:
Welcome to \S{ANSI_COLOR}\S{NAME}0m \S{VERSION}
Report bugs at \S{BUG_REPORT_URL}.
See http://www.freedesktop.org/software/systemd/man/os-release.html
fr more details about /etc/issue.
Based on patch from Bill Nottingham <notting@redhat.com>.

Earlier test failed when user had write permission, but was not in
special group that owns terminal devices, usually tty.
This made write(1) to fail for root, if the root did not happen to be in
tty group. In this commit root is granted ot write to anyone, even if
they have mesg(1) turned off. For an user who is trying to write to own
other session the group write bit is significant only for whether mesg(1)
are enabled.

Sessions that has in utmp data ut_line begining with ':' are skipped.
This is done to avoid write errors to devices such as '/dev/:0'. For
example wdm is reported to to generate such utmp line.
Perhaps in future this code should be revalidated. If an utmp data
contains broken device lines it might be best inform user with a error
message, rather than skipping silently suspicious device entries.
