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

This patch adds CELT header parsing and granulepos interpretation to
liboggz, so that CELT can be used with oggzdump, oggzmerge, oggz-validate
etc., and reports samplerate and channels in oggzinfo.
NB. This also expands the public OggzStreamContent enum to include
OGGZ_CONTENT_CELT

oggz_write_feed() when a bos page is encountered. This sets the content type
for writing, so that oggz can know how to structure comment packets etc.

This function is used by oggz_read to identify a bos page as soon as it is
read, before any packet extraction is done. We do this on a page so that the
content-type is known before the user's read_page callback is called.

Always calculate granulepos value, even if one is available in bitstream.  These get reported via different mechanisms so the library user can decide which to trust.
Modifications to oggzdump to indicate which granulepos values are virtual (i.e. calculated) and which granulepos values are different to those stored in the bitstream.

granulepos is not given in Ogg framing). This tracks the current granulepos
and determines the block size by reading the FLAC frame header. Note that
this patch doesn't handle blocksize codes 0000, 0110 or 0111, which
require poking elsewhere to get the actual value. Nevertheless this patch
appears to handle the common case framing, and in any case it is very rare
for Ogg FLAC packets to not have a granulepos.
  * Handles both old-style Ogg Flac framing ("Flac0") and current framing
  * Tested on all flac-in-ogg files from MPlayer samples:
    http://www1.mplayerhq.hu/MPlayer/samples/ogg/flac-in-ogg/
  * Tested with valgrind --leakcheck=yes on src/examples/read-file (no leaks)

  + oggz_comment_() functions for querying comments per logical bitstream, and
                    for adding/removing comments in-memory
  + added comment-test to test suite
  + tested under valgrind (no leaks)

opened with the OGGZ_AUTO flag, the content type of a stream can be retrieved
using oggz_stream_get_content once the first page of that stream has been read.
A human-readable string representation can also be retrieved using 
oggz_stream_get_content_type.

Updated oggzinfo, etc. to use liboggz variant of content type detection.
