Hi,

This patch removes the ->sendfile() hook from the file_operations
structure, and replaces the sys_sendfile() mechanism to be based on
->splice_read() instead. There should be no functional changes.

Work to be done:

- The ext2 xip support needs a splice_read() implementation, currently I
  just if 0'ed out the send xip_file_sendfile(). CC'ed Carsten, who
  seems to be the author of this code.

- shmem needs a splice_read() implementation. Optimistically CC'ed Hugh.

- nfds: The ->rq_sendfile_ok optimization is gone for now. I can't
  determine the value of it, but I'm assuming it's there for a reason.
  Any chance this can be converted to splice, or use something else than
  ->sendfile()? CC'ed Neil.

- relay: needs a splice_read() implementation. I think Tom already has
  one, CC'ed him.

Apart from that, it was mostly straight forward. Almost everybody uses
generic_file_sendfile(), which makes the conversion easy. I changed loop
to use do_generic_file_read() instead of sendfile, it works for me...

Patch is against current git.
