- much of the striping configuration managment and setup builds up
  this patch
- the mds has a new lovconfig command to tell it the UUID's and
  default striping pattern of the targets it needs to use (these are
  the UUID's of the OSC's typically).
- To make this scalable I changed some of the memory management in the
  class ioctl handling
- The LOV device has a trivial attach method and setup only tells it
  what MDC to use to get its information, by giving it the MDC-UUID.
- As discussed before, the MDS really provides the persistent storage
  for the LOV, what little it needs.  So during the obd_connect call
  for the object storage target (which is made from read_super) the
  storage target learns how it is striped and then connects to all the
  targets.
- We are in need of better configuration scripts for this stuff and
  tomorrow we will push the XML configurations a little further.
- Updated the documentation
- Began to cleanup the /proc/lustre/ stuff -- have some neat ideas
  about that and SNMP now.
