  Log:
  Make ftruncate a 'struct file' operation rather than a vnode operation.
  This makes it possible to support ftruncate() on non-vnode file types in
  the future.
  - 'struct fileops' grows a 'fo_truncate' method to handle an ftruncate() on
    a given file descriptor.
  - ftruncate() moves to kern/sys_generic.c and now just fetches a file
    object and invokes fo_truncate().
  - The vnode-specific portions of ftruncate() move to vn_truncate() in
    vfs_vnops.c which implements fo_truncate() for vnode file types.
  - Non-vnode file types return EINVAL in their fo_truncate() method.
