This patch adds support for decoding Closed Captions in ATSC mpeg streams.
 These are the "old-style" EIA-608 captions which seem to be present in
 most ATSC broadcasts.  This patch also includes decoding of Closed
 Captions (not subtitles) in DVD mpeg streams.  Both caption-styles are
 contained in User Data mpeg packets.  For the captions to be correctly
 displayed, the patch in Ticket #667 is required.

 The patch is in two parts.  The first part moves the existing CC decoding
 support from NuppelVideoRecorder to a new CCDecoder class so that it can
 be shared with the frontend.  The second part adds the actual support for
 ATSC and DVD decoding.
