tty-ask-password-agent-on-console.patch

The tool systemd-tty-ask-password-agent used with the option --console does
only ask the password on the last console configured in the kernel command
line.
That is that if e.g.

   console=ttyS0,115200 console=tty0

is used the passphrase for a e.g. crypted device will only be asked on
/dev/tty1 at boot.  To fix this I've ported my old multi console device support
from sulogin to the tty-ask-password-agent source.  Maybe it is worthy enough
to integrate and/or port this solution into systemd.  That is that the two
functions collect_consoles() and free_consoles() as well as the struct console
could become be part of src/share/util.c below resolve_dev_console()
