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.
