Subject: [PATCH] Lots of things here: - hopefully fix for bug 519 (don't write
 stripe MD to the MDS each open) - cleanup of delayed-file-create code -
 proper abstraction of user-supplied stripe data into LOV/OSC - fix bogus LBUG
 in ll_file_release when lsm is NULL (just means that   no objects were
 allocated for this file yet) - make lstripe help less verbose - remove old
 lovstripe program, it is obsoleted by lstripe.

Sadly, lstripe does not yet work, although acceptance-small.sh runs
fine so I'm checking this in so I can debug lstripe under UML.
