Subject: [PATCH] open-osd: (tgt-merge-1.0.0) Remove auto configuration of /tmp
 osd-target

Few changes at tgt
* Use patch by Arne Redlich <arne.redlich@googlemail.com> that removes
  the dummy RAID controller from LUN 0. At startup tgt loads without
  any LUN(s)
* Do not use the patch that adds a default osd-target at
  /tmp/tgt-$(id -nu). Again tgt is initially empty.
* Rebase on tgt version 1.0.0

Therefore at ./up load some osd-targets:
* At top of script file define some osd backhand directories. Now easily
  changeable by users
* optionally load all (up to 4) defined backhands as LUNs.
