Message:

Parse BOS page before calling first page reader callback.
Fixes ticket:416, "oggz-chop writes wrong granulerate in fisbone"
by correcting the library behaviour.

  • Rename internal oggz_auto_get_granulerate() to oggz_auto_read_bos_packet()
  • Add internal oggz_auto_read_bos_page()
  • Use oggz_auto_read_bos_page() when a new bos page is encountered, before
    calling the user's page reader callback
  • Correct the granulerate denominator reported by oggz_get_granulerate,
    removing the internal OGGZ_AUTO_MULT scaling
