Headsup: significant libcddb update for devel repo

[Hans de Goede]

Hi all,

I've just updated libcddb to the ABI and API compatible 1.3.0 release,
here is whats new:

* [IMPORTANT] The text search functionality currently does not work
  anymore.  This feature uses the search form on the freedb.org
  website.  But since this form has disappeared, text search fails.
  In the mean time you might make use of the album command of the
  freedb2.org servers (see below).

* [NEW] Support was added for the 'album' command of the freedb2.org
  servers.  This feature can be used to do a text search for a certain
  album.  It does not perform any HTML page parsing but uses an
  extension of the CDDB protocol.  As input the function needs a disc
  with either the artist or title filled in.  The results are similar
  as for the query command; i.e. a list of matching disc IDs together
  with their categories.  The example program also supports this
  feature.

* [NEW] Functions where added to set (libcddb_set_flags) or reset
  (libcddb_reset_flags) some flags.  The flags used influence the
  behaviour of the library.  By default all flags are disabled.
  Currently the following flags are available:
  - CDDB_F_EMPTY_STR: When this flag is set, the library will never
    return a NULL pointer for a string.  Instead the empty string will
    be returned.
  - CDDB_F_NO_TRACK_ARTIST: When this flag is set, the library will
    not return the disc artist if the track artist is undefined.  A
    NULL pointer (or the empty string if CDDB_F_EMPTY_STR is set) will
    be returned instead.

Regards,

Hans
