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.
