Pedestal:  Uninline virtual ApertureFromBounds()

Virtual member functions don't get inlined anyway, so don't define it in
the header.
[FIX] recall:  Fix thinko in CFM frame handling

In addition to failing to actually decrement the reported frame pointer,
the previous code instead decremented the longword at what was the frame
pointer.  Since this is unused stack, it probably didn't break anything,
though it would definitely crash on a 68000 due to the odd address.
