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.
