Underline option arguments, and use bold for options. Avoid use of \f
font style change in paragraphs, but use them when describing options.

Commit 3393c136 caused regression. The klogctl() logging range is 1-8,
but the value 0 is special according to setterm.1 manual page. It turns
on loging, same way as '-msg on' option.

It is enough trouble to keep usage output aligned with getopt() parsing,
manual page, and bash-completion, so get rid of the unnecessary effort
duplication.

Earlier the function was in the middle of option parsing code segment,
and screendump() required function prototype.

Check the input numbers are numbers, which makes also the code shorter,
and user experience better as half invalid imputs will error.

While the -version style options will work for next unknown number of
years start moving towards user interface that has way of invoking long
options as most of the other commands.

The getopt_long_only() has advantage of allowing one and two hyphen
versions of options, for example -help and --help. Secondly the getopt
function family from libc can ensure some options requiring arguments,
while other are optional, and some should not accept argument at all.
That makes option parsing more robust.
Unfortunately retiring the old option parsing makes this change greater
than preferred. Assuming not mistakes happen the new code works
functionally exactly as the old did.

The issue file escape sequences \4 and \6 prints the host IP when no
interface is specified. That's useless on some virtual machines where
gethostname()+getaddrinfo() returns 127.0.0.1.
The seems better to print IP of the "best" interface (UP, RUNNING, non-LOOPBACK)
and use gethostname() as painful fallback only.

For this approach do not use the ioctl TIOCMGET anymore as this
is for real serial lines only. But switch over to use the ioctl
KDGKBMODE as this is unique to the virtual console lines only.

That is that there are several consoles, the /dev/ttyS0 which
is type of ibm3215 and a dumb terminal, then there is the device
/dev/3270/tty1 which can handle ANSI color escape sequences and is
a ibm327x terminal, and the /dev/ttyS1 which is a vt220 terminal.
The macro is_speed() in agetty.c allows to distinguish between the
terminal line (/dev)3270/tty1 and the speed options on the command
line used in
/run/systemd/generator/getty.target.wants/serial-getty@3270-tty1.service
which is a symbolic link to /usr/lib/systemd/system/serial-getty@.service

The nowadays used plymouth locks the devices used for the system
console which causes that agetty as well as sulogin can not modify
the termios settings of e.g. the serial devices of the systenm console.

symbolic variable that is recognized by gdb.

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.
