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.

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.

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.

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>.

In include/bits/utmp.h the ut_user and ut_time macros are marked with
comment they are backwards compatibility hacks. It is probably best to
avoid use of these macros where ever possible.

* also increase sleep when O_NONBLOCK used (grr.. this is so stupid
thing, do we really need O_NONBLOCK for the stupid serial lines?)

Now the -L option allows to explicitly enable CLOCAL flag.
Unfortunately sometimes it's necessary to clear the flag. This patch
add optional argument =<mode> to specify 'auto', 'always' and 'never'
to control CLOCAL flag.

this one moves the init_chardata to include/ttyutils.h as well as to
lib/include/ttyutils.c. Also the macros CTL/CTRL are fixed in
agetty.c and sulogin.c to use the XOR variant CTL.

We need way to disable the default kill and erase agetty chars to make
the getty usable for Active Directory users with '@' in username.
It seems that the most extendible solution is to add options that
allow to complete control additional erase/kill chars. If you specify
empty strings then the chars are disabled at all.
Note that this patch is backwardly compatible.

The --autologin prints
hostname login: username (automatic login)
message. This commit allows to suppress the message at all if
--skip-login (aka skip prompt) is specified.
It means that
agetty --skip-login --noissue --autologin foouser
does completely silent autologin.

on controlling terminal should be optional too.
