 965         Rewrite SPU overlay handling code.  Put overlay calls stubs in the
 966         overlays where possible.  Use a faster call stub, or optionally at
 967         compile time, a more compact stub.  Double size of _ovly_buf_table
 968         so that low bit of _ovly_table.buf can be used as a "present" bit.
 969         Reserve an extra _ovly_table entry for index zero.
