Unhiding time lapse api's, removing setTimeLapseParameters()

- Removing setTimeLapseParameters() as its functionality is taken
  over by setProfile() and setCaptureRate()
- Unhiding setCaptureRate()
- made setAuxiliaryOutputFile() public.
- Changed setAuxVideoParameters() to compute video size and bitrate
  using CamcorderProfile::QUALITY_HIGH. Also made it private as it
  now just needs to be called from setAuxiliaryOutputFile().
