pnfs: encode_layoutcommit
Add a layout driver method to encode the layout type specific opaque part of layout commit in-line in the xdr stream. Currently, the pnfs-objects layout driver uses it to encode metadata hints to the MDS and the blocks layout driver to commit provisionally allocated extents to the file.
