ocfs2: Support xfs style space reservation ioctls
We re-use the RESVSP/UNRESVSP ioctls from xfs which allow the user to
allocate and deallocate regions to a file without zeroing data or changing
i_size.
Though renamed, the structure passed in from user is identical to struct
xfs_flock64. The three fields that are actually used right now are l_whence,
l_start and l_len.
This should get ocfs2 immediate compatibility with userspace software using
the pre-existing xfs ioctls.
