    kern - Make lseek(2) generic
    
    * Extend fileops with fo_seek function allowing pluggable lseek(2)
      implementations. Part of preparation for linux DMA-BUF compat API.
    
    * Move current vnode lseek implementation into vnode and devfs fileops.
      Code is exactly the same in both, note about duplication added.
    
    * Set remaining fileops to badfo_seek.
