2196 Rewrite SPU overlay handling code. Put overlay calls stubs in the
2197 overlays where possible. Use a faster call stub, or optionally at
2198 compile time, a more compact stub. Double size of _ovly_buf_table
2199 so that low bit of _ovly_table.buf can be used as a "present" bit.
2200 Reserve an extra _ovly_table entry for index zero.
