Merge scstadmin from trunk. Hence add support for saving and restoring the ALUA state, unify the qla2x00t/iSCSI-SCST and SCST init scripts, compute the SCST handler kernel module list from /etc/scst.conf and add man pages for scstadmin, /etc/scst.conf and /etc/default/scst. (svn merge -r3389:3982 https://scst.svn.sourceforge.net/svnroot/scst/trunk/scstadmin/Makefile Makefile)
