Make s390 3215 console work

that is use EPOLLOUT|EPOLLONESHOT to control if we can write to ttyS0 in nonblocking mode and if not reenable EPOLLOUT|EPOLLONESHOT.

At boot set for ttyS0 via vmcp API nonblocking MORE mode with `0 0'. It beeps but boots.

Increase patch level

Make it work on s390x (still no 3215 console)

This is a bug fix release. But still no support in conmode 3215 as there is a race triggered by using conmode 3215. The order of the systemd units seems to change with this console mode.

Better 3270 console support

Use uevent below /sys file system

Handel BS on password prompt as well

Drop spining code as systemd uses clear to end of line escape sequence (hard coded!) for its "cylon" lines.

The asking variable is not shared

Allow password asking prompt to be repeated if empty. Make spinner support UTF-8 multibyte conform. Spinner lines of system still not handled.

Make sure that password prompt is seen

Use a temporary buffer to be silent during asking passwords. And stop system console output during password questions only if temporary buffer becomes short. As well as do coloring on /dev/ttysclp0 for S390.

UTMP support is gone, remove dependency

UTMP support is gone, remove dependency
also add support for initramfs at shutdown.
