Setting and unsetting the IFS variable is tricky. To be on the
safe side we should always reset the IFS variable to its original
value after parsing.

Add new functions require_binaries() and require_any_binary() to be used
in the check() section of module-setup.sh.
These functions print a warning line telling the user, which binary is
missing for the specific dracut module.
This unifies the way of checking for binaries and makes the life of an
initramfs creator easier, if he wants to find out why a specific dracut
module is not included in the initramfs.
normalize_dasd_arg is a RedHat specific script, so no point
installing this module if the script isn't present.

The primary source for dasd initialization script and udev rules is
now in s390utils package. The s390utils-base subpackage, that carries
the required files, is always installed on s390/s390x, because it's
part of the Core group in comps.

The new rd_DASD parameter allows dracut to handle multiple rd_DASD
options. One parameter per DASD. The syntax is:
rd_DASD=<device path>[,readonly=X][,erplog=X][,use_diag=X][,failfast=X]
The device path is a CCW device path, such as 0.0.0200. The optional
parameters are sysfs attributes for the DASD. The X value can be 0 or
1. Dracut will write out each of the rd_DASD settings to
/etc/dasd.conf and on bootup, the dasdconf.sh script will parse this
file and bring each DASD online with the specified attribute settings.
