cdda: misc cleanup
- use
INVALID_SECTORfor unset sector/LBA start/stop values - read/write
vlc_tick_tbased on sector values andCD_ROM_CDDA_FRAMESrather than 40000/3 values (looking wrong) - use
CD_ROM_CDDA_FRAMESfor MSF_TO_LBA(2) as well as the MSF (Minute/Second/Frame) time corresponds to playback times for audio CDs
Similar to !582 (merged) without the PTS changes.
