tsdemux: Support Bluray DTS/DTS-HD and AC3+/TrueHD streams

Browse source 
Apart from just adding detection of the proper stream type, we also need to only
output the first substream (0x71) which contains the core substream.

While this does not provide *full* DTS-HD support (since it will miss the complementary
substreams), it will still work in the way legacy (non-DTS-HD) bluray players would work.
