validate: Use presence of STREAM_START to detect track switching

Browse source 
When doing a track switch, the only reliable way to detect that it
happened is whether a new STREAM_START arrives.
Relying on a DISCONT buffer is not satisfactory, since there might
not have been an element setting that flag upstream.

Checking whether the first buffer after a STREAM_START has the
DISCONT flag properly set should be done in parallel
