Steve, Pavel,

Please find a small patch that adds fiemap support to smb2+
This patch will conflict with the previous SEEK_HOLE/DATA patch
but please disregard that patch for a now. There are things we need to
think about with punch-hole and seek/data/hole first.
I will send a separate email about that.

With this patch, filefrag -v will work against a windows16 server with sparse files with holes.
This also allows the 'cp' commands to operate much more efficient if copying
large sparse files from a smb2+ share.
