    mpeg[pt]sdemux: Add support for AAC LATM/LOAS streams

    Fixes bug #615681.

However, the rea issue is that aacparse gets plugged by playbin2, as it
advertises it can handle audio/mpeg, mpegversion: { 2, 4 }, and will output
something which does not include loas as a stream format. The input here has
loas as a stream format (which matches aacparse's generic template), but
there's no way to express in caps "I do anything except that". If I was to
specify "I do A, B, and C", it would stop working for inputs which do not
specify any stream format.

So, not sure what to do here. We have other decoders which have template caps
coser to what's being passed, so that would make more sense to plug them, but
that would not solve the main issue, just sidestep it...
