[PATCH] init: handle kexec clean reboot

Hi Sam !

H is not the name of a program. It is just the information passed
to to indicate "halt".

The way it is defined is the cleanest way I know. If you want to
pass the name for a program (e.g. for kexec) you add another
keyword or letter (e.g. "X yourprogram" NL). This way there is no
conflict and you can pass whatever info you like. All this is not
defined inside Busybox binary. The script determines how the
information is used. That is you may define it as you like. Only
three values need to be predefined for the current three boot
options so the commands "halt", "reboot" and "poweroff" can
trigger the required function.
