Anna Schumaker 2e72448b07 NFS: Add COPY nfs operation
This adds the copy_range file_ops function pointer used by the
sys_copy_range() function call.  This patch only implements sync copies,
so if an async copy happens we decode the stateid and ignore it.

Anna Schumaker 1c6dcbe5ce NFS: Implement SEEK
The SEEK operation is used when an application makes an lseek call with
either the SEEK_HOLE or SEEK_DATA flags set.  I fall back on
nfs_file_llseek() if the server does not have SEEK support.
