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