------------------------------+--------------------------------
 With `channel_set_cell_handlers()`, two handlers are set in a channel
 which are for fixed size cell and variable length cell.

 Turns out that the `channel->var_cell_handler` is never used since all var
 cell are processed through the channel TLS layer directly:

 `connection_or_process_cells_from_inbuf()`
  -> `channel_tls_handle_var_cell()`.

 Which means we can remove a good 70+ lines of dead code.
