After further investigations, tsparse needs to be refactored a bit to:
* Not push out per-program packets individually, but instead aggregate them all
until the incoming buffer has been fully parsed
* On input-done, create *one* buffer per program pad and set the incoming
buffer timestamp on it
* Be smarter about which packets should go on which program pad:
 1) If it's from a pid that the program handles take it (we know we need it)
 2) Else if it's from a pid of another program refuse it (we know we don't need
it)
 3) Else take it (It's a global/generic MPTS pid)

Furthermore, we need to make sure that if a program/bin is listening
synchronously to the bus messages, and especially the PAT, it can
request/release a program pad *before* the data for that program goes out.
