- Remove slot abstraction from internal API and all reader drivers. CT-API (from where it all comes from) readers with multiple slots (if still found) can be presented as separate readers, OpenCT should remove the slot abstraction, PC/SC never knew about it. None of the tools knew how to use slots.
- Add sc_cancel (translates to SCardCancel)
- Re-implement sc_wait_for_event; support a blocking call.
- Replace the "int reader" API with "* sc_reader_t" style; add "Get reader by name" functionality.
- Remove "action" parameter from sc_disconnect_card() (was not used)
