  Send REC_PENDING event before recording starts

Fix the logic that sends the REC_PENDING event.
- REC_PENDING event is sent always before the REC_STARTED.
- REC_PENDING event is sent at 120, 90, 60 and 30 seconds before the start of the recording.
- Start of the recording is the scheduled program start time plus the RecordPreRoll setting value.
- When a recording is scheduled to start recording immediately then there is
  one REC_PENDING event with 0 seconds immediately followed by the REC_STARTED event.
- The setting WakeUpThreshold specifies how early the slave backends are signaled to start
  before the recording is started. This setting is used as configured, but now with a minimum
  value of RecordPreRoll plus 120 seconds so that there is always time for the REC_PENDING events.
