1003         Rewrite SPU overlay handling code.  Put overlay calls stubs in the
1004         overlays where possible.  Use a faster call stub, or optionally at
1005         compile time, a more compact stub.  Double size of _ovly_buf_table
1006         so that low bit of _ovly_table.buf can be used as a "present" bit.
