Add 64-bit IO manager operations to struct_io_manager.

In order to provide 64-bit block support for IO managers an maintain
ABI compatibility with the old API, some new functions need to be
added to struct_io_manger.  Luckily, strcut_io_manager has some
reserved space that we can use to add these new functions.
