>From previous reconstruction, dracut will put the dependency code into
dracut-init.sh, and independency code to dracut-functions.sh. Then any
script can source the public dracut-function.sh script.
There are still a lot of errors when dracut-functions.sh is sourced in
third-part script. So this patch try to move the dependency code from
dracut-functions.sh to dracut-init.sh.
Here are some sorts of errors about the dependency.
