add Open+LayoutGet RPCs

This patch adds support for Open+LayoutGet RPCs to the NFSv4.1/pNFS client,
reducing the RPC count by avoiding a separate RPC for LayoutGet.

URL: https://svnweb.freebsd.org/changeset/base/320322

Log:
  Add two new compound RPCs to the NFSv4.1/pNFS client.

  When the NFSv4.1 client is doing pNFS, it needs to get an Open and
  a Layout for every file it will be doing I/O on. The current code
  does two separate RPCs to get these. This patch adds two new compounds
  that do the both the Open and LayoutGet in the same RPC, reducing the
  RPC count.
  It also factors out the code that sets up and parses the LayoutGet operation
  into separate functions, so that the code doesn't get duplicated for
  these new RPCs.
  This patch is fairly large, but should only affect the NFSv4.1 client
  when the "pnfs" option is specified.
