Add new event types for timeout & carrier report
Move timeout handling from ir_raw_event_store_with_filter to
ir-lirc-codec, where it is really needed.
Now lirc bridge ensures proper gap handling.
Extend lirc bridge for carrier & timeout reports
Note: all new ir_raw_event variables now should be initialized
like that:
struct ir_raw_event ev = ir_new_event;
