Rick Macklem b949cc41d1 Add Flex File Layout support to the NFSv4.1 pNFS client. 
This patch adds support for the Flexible File Layout to the pNFS client.
Although the patch is rather large, it should only affect NFS mounts
using the "pnfs" option against pNFS servers that do not support File
Layout.
There are still a couple of things missing from the Flexible File Layout
client implementation:
- The code does not yet do a LayoutReturn with I/O error stats when
  I/O error(s) occur when attempting to do I/O on a DS.
  This will be fixed in a future commit, since it is important for the
  MDS to know that I/O on a DS is failing.
- The current code does writes and commits to mirror DSs serially.
  Making them happen concurrently will be done in a future commit,
  after discussion on freebsd-current@ on the best way to do this.
- The code does not handle NFSv4.0 DSs. Since there is no extant pNFS
  server that implements NFSv4.0 DSs and NFSv4.1 DSs makes more sense
  now, I don't intend to implement this until there is a need for it.
  There is support for NFSv4.1 and NFSv3 DSs.
