ose: Rewrite resolve_signal API for ose drivers

This new API has less impact on the check_io code and
also removes the callback from ErlDrvEntry. The downside
is that you have to give the resolve function when creating
each event.

Also the mode if the resolve was removed as this mimics the
win32 code and decreases complexity.
