ATSC Cleanups

Hello All,

I’ve been recently playing with the ATSC decoding functions and have a
couple questions. First the last time ATSC was discussed in any real
detail was 4 years ago ( according to Google history of this mailing
list ), and the converting of GR0.9 code to GR2.0 was raised, but in
the repository all the functions look like they are 2.0, what still
needs converted and why are all the files mirrored as the old versions
( and ) are the old versions still needed?
Also the python code to put the blocks together seem dated, Is there
any reason to use pipes and not just have all the code in one file and
use IPC? ( also /tmp/atsc_pipe_4 is never used )
